8.2.2 Ground cable
TG new
MAN frames are voltage-free in that neither the positive nor the ground cable is connected to it. Together with the positive cable, consumers must always have their own ground cables routed to them.
Ground points to which the bodybuilder can connect ground cables are located as follows:
• Next to the central electrical system
• Behind the instrumentation
• D08: Central ground point on the frame, left, at the height of the gearbox
• (D15 and D26): On the right rear engine mount
• D38: On the left rear engine mount
No more than a total of 10 A (actual current demand) may be tapped at the ground points behind the central electrics box and behind the combined instrument. Cigarette lighters and any extra sockets have their own power limitations, which can be found in the operating manual.
The negative cable of the body manufacturer may generally be connected to the central ground point (see described above). It may be connected to the negative terminal of the batteries if the battery terminal has sufficient space to connect the ground cable.
Further information and instructions on connecting additional consumers can be found in Chapter III, Section 8.4 “Additional consumers”.

8.2.3 Wiring harnesses for wheelbase extensions
TG new
When wheelbases are extended, control units and sensors associated with the rear axle also have to be relocated along with the axle.As a basic principle, CAN wiring harnesses may never be cut and lengthened and for this reason, MAN offers cable-harness extensions each with a 1500 mm length of corrugated tubing. If these extensions are not sufficient, two of the cable harnesses described here can be connected in series. Only when the method described here is used can the movement of control units and sensors be considered as approved.
Control units and sensors associated with the rear axle
Basic equipment on all TG vehicles:
• EBS axle modulator (one module for all rear axles)• Switch, check for parking brake
In the case of air suspension on the rear axle(s), the following are added:
• Displacement sensor (left and right)• Valve block, ECAS
Depending on version and equipment, the following cabling is fitted.
• Differential-lock plug connector
Cable extensions from the EBS axle-modulator to the sensors on the respective wheel (speed sensors, brake-lining wear sensors) are not necessary if the EBS axle-modulator module is relocated together with the rear axle.

ImplementationIn some cases, cable extensions entail minor reworking of the original cable-harness plug. This is explained in detail below, where the small items that are necessary (e.g. plug housings, locking mechanisms and adapters) are referred to by their codes. Table 33-III lists a breakdown of the associated item numbers.

Each of the speed and brake lining wear sensors itemised in Table 37-III below are plugged into the corresponding EBS axle modulator on the rear axles. The associated cabling does not need to be extended when extending the wheelbase because the axle modulator is moved together with the rear axle. For reasons of completeness and for special designs, extension cable harnesses for speed and brake lining wear sensors are nevertheless available.

Depending on the body, it may also be necessary to relocate the side marker lamps (the statutory regulations applicable to lighting system are to be observed, see chapter III section 8.6). If the connection cables are too short, cable-harness extensions in various lengths are available. Only original MAN side marker lamps using LED technology are permitted. Use of any other lamps will result in the partial operating permit for the lighting system to become invalid. Side marker lamps with incandescent bulbs will damage the central on-board computer.

8.3 Interfaces on the vehicle, preparations for the body
TG new
No intervention in the on-board network is permitted except via the interfaces provided by MAN.
Signals must not be tapped from the CAN bus, the only exception being the bodybuilder’s CAN bus (see TG interface of the control unit for external data exchange)
The interfaces provided by MAN are fully documented in the sections below. Interfaces are, for example:
• Liftgate
• Engine start/stop device
• Intermediate speed control
• FMS interface
• Tapping into the engine-on signal
• Tapping into the speed signal
• Tapping into the reverse-gear signal
• Interface for data exchange with body, behind front panel and external engine intermediate speed control
• Interface for data exchange with body, behind cab (DIN)
If a vehicle is ordered with ready body fittings (e.g. start/stop device at end of frame) these will be installed ex works and partly connected. The instrumentation is prepared as ordered. Before commissioning the body fittings, the bodybuilder must ensure that it has used the applicable versions of wiring diagrams and cable-harness drawings in each case (see also Chapter III, Section 8.2.5).
MAN affixes transport securing devices (on the interfaces behind the front flap on the co-driver’s side) for delivery of a vehicle to the bodymaker. These devices must be properly removed before using an interface.
Retrofitting interfaces and/or bodywork preparations can be complicated and costly, requiring the support of an electronics specialist from the MAN Service Organisation.
Remote transmission from the mass storage of digital tachographs and information contained on the driver card.
MAN supports the manufacturer-independent remote transmission of data from the mass storage of digital tachographs and information contained on the driver card (RDL = remote download). The corresponding interface is published on the Internet at www.fms-standard.com.

8.3.1 Tapping into the engine-on (D+) signal
TG new
The engine-on signal can be tapped at the plug X1428/pin 4 (cable number 501001). The plug X1428 is not included in the standard scope of delivery and can be ordered using the special equipment 0P2KK "Preparation, electrical, for gritter (displacement/speed signal)".
6-pin plug connector: X1428
Colour and coding: natural/6

07.91202-0610 (1<0) 07.91202-0611 (2<5)
If the plug X1428 is not present in the vehicle, it is possible to provide the D+ signal through an MAN service. For this purpose, a separate plug must be connected on the CVM at plug B pin 4 and the body manufacturer provided with the D+ signal in this way.
Important notice The D+ signal: - may not be tapped from the alternator - may not be tapped externally directly from the CVM

8.3.2 Electrical interface for liftgate
TG new
Electrohydraulic liftgates require very careful design of the electrical supply.
Ideally the electrical interface for a liftgate is provided ex works. Retrofitting the interface is a complex procedure and requires intervention in the vehicle‘s electrical system, which must only be carried out by correspondingly qualified personnel at MAN Service outlets.
• Button• Check lamp (display message in the event of liftgate being open)• Start lock (display message in the event of a start-up attempt when liftgate is switched on)• Power supply for liftgate.
The body manufacturer must check the wiring of the liftgate to ensure it is suitable for MAN vehicles. In normal operation, the interface A358 must only be actuated with 24-V continuous signals – not with flash impulses. In the event of a fault, a clocked signal may be applied to the relay K467 for a short time.
For operating an electrohydraulic liftgate on the TGL/TGM the required battery capacity is 2 x 155 Ah.
For connection to the electric interface of the hydraulic liftgate, see the supplementary wiring diagrams below.

8.3.3 Engine-Start-stop system
TG new
The engine start-stop system enables the vehicle’s engine to be started or stopped via a remote control or switch outside the cab.
The engine start-stop system is a system that works independently of the intermediate speed control interface and must be ordered separately.
The following variants of the engine start-stop system are available ex-works.

It must be ensured here that both the original MAN components and the documented connection options and installation locations are used.
In addition, there is the option to implement the "engine start/stop device" using the CAN data bus. A prerequisite for this is that the "Interface for data exchange with body, behind front panel and external engine intermediate speed control" (sales code 0P2NA) is installed in the vehicle ex works. A description of this can be found in the associated interface description.
Special parametrisation is not required for the engine start/stop functionality.
Important noticeIf the bodybuilder has installed the circuitry, the designation “Engine start-stop” must be used. This must not be confused with the term “Emergency stop”.

8.3.4 Tapping into the speed signal
TG new
It is possible to tap into the speed signal from the tachograph. It must be ensured that the load on the corresponding plug contact does not exceed 1 mA!
This generally equates to two connected peripheral units. Should this option for tapping the signal be inadequate then the following output multipliers bearing the MAN codes can be connected:
• 81.25311-0022 (3 • v-pulse output, max. load 1 mA for each output) or
• 88.27120-0003 (5 • v-pulse output, max. load 1 mA for each output).
Option for tapping the ‘B7 signal’ = speed signal:
• At plug B/plug contact 7 or plug contact 6 on the rear of the tachograph
• At the plug connector X6434/contact 2 (cable 165000). The plug connector is located behind a cover on the driver-side A-pillar in the area of the driver footwell.
• At the 6-pin plug connector X1428/contact 6 (cable 161018) in the area of the central electrical system. The plug X1428 is not included in the standard scope of delivery and can be ordered using the sales code 0P2KK "Preparation, electrical, for gritter (displacement/speed signal).

8.3.7 Interface for reversing-camera preparation
TG new
The electrical interface for the rear-view camera preparation makes it possible to connect either one or two rear-view cameras and show the image on the screen of the MAN Radio MMT advanced. The system automatically switches to the camera image when reverse gear is engaged or when the camera button is manually pressed.
It is not possible to activate a camera image via a contact on the MMT.
The rear-view camera preparation interface is a system independent of the MAN radio MMT advanced, and must be ordered separately using the sales code for the rear-view camera preparation.
Preparation for rear-view cameras Sales code
Preparation for rear-view camera, 1 unit 0P2D0
Preparation for rear-view camera, 1 unit, (camera linked to reverse gear) 0P2D1
Preparation for rear-view camera, 2 units 0P2D2
Preparation for rear-view camera, 2 units, (camera 1 linked to reverse gear) 0P2D3
If the interface is not available ex works, it is possible to retrofit it. Because a retrofit is costly and requires accessto the vehicle electrical circuit, we recommend having it done at a MAN Service centre.
Some camera manufacturers offer an adapter cable suitable for the MAN interface (rear-view camera preparation), which can also be sourced from an MAN specialist workshop.
Depending on the customer's wishes, the interface (plug for camera 1 and 2) is located behind the front panel on the left vehicle side, when viewed in the direction of travel, once the housing cover has been removed. If an extension is connected there ex works, the interface is located behind the cab on the left vehicle side in the frame, at the height of the gearbox.

8.3.8 Interface description for tipper display preparation
TG new
Preparation for the tipper display in the instrumentation can be ordered ex works using the sales code 0P2M5 (Tipper display, cab (symbols)). This equipment is not included in the standard scope of delivery. Retrofitting can be carried out by an MAN service outlet. In this process, the corresponding wiring and parametrisation on the vehicle must be retrofitted.
In the equipment for the preparation for a tipper display, there is a plug connector with a socket on a rolled-up cable harness in the area of the centre of the frame.
A socket is installed on the plug connector at the factory; this must be removed. Only then is the plug connector to be connected to the sensor required for the body. The factory-installed socket includes a resistor and must be disposed of properly.
In order to ensure the functionality of the tipper display and an interruption-free cable, a diagnosable sensor must be installed (see the following circuit diagram).
The resistance range of the resistor R1 must be 1 kOhm to 5 kOhm here and the range of the resistor R2 must be 6 kOhm to 22 kOhm here. A break in the line, a faulty sensor or a short circuit can therefore be reliably identified and, if required, displayed.
Fig.: Schematic diagram of a sensor for the tipper display
Functional description:
When the tipper body is lifted, the information message "tipper operation" and the symbol "tipper up" are displayed in the instrumentation if the vehicle is at a standstill and when driving at a vehicle speed of up to 10 km/h. As from a vehicle speed of 10 km/h, the stop message "tipper operation" and the symbol "tipper up" are displayed with a signal tone in the instrumentation. Further information can be found in the operator's manual for the relevant vehicle.

8.4 Additional consumers
TG new
As a basic principle, the connection of additional consumers is possible. lf additional electrical loads are retrofted, observe the following: • There are no spare fuses in the central electrical system for use by the bodybuilder. • Do not tap into existing vehicle power circuits. • Every added circuit must be adequately scaled and protected by its own fuses. The dimensioning
of the fuse is to protect the cable and not protect the system connected to it. • When installing additional fuse carriers, only those with protection type IP54 and fire protection
class UL94 V0 should be used. Fuse carriers that are open underneath (Fig. 106-III) and ring fuses (Fig. 107-III) are not allowed. Fig. 108-III shows a fuse carrier with the MAN item number 83.25441-0661 that fulfils the above requirements and can be used. The body manufacturer bears sole responsibility if this is not observed and damage occurs as a result.
• Electrical systems must offer sufficient protection against all possible electrical faults and environmental influences without affecting the vehicle electrics.
• Freedom from feedback must be ensured in all cases. When selecting the size of the wire cross-section, the voltage drop and the heating of the conductor must be taken into account. Cross-sections below 0.75 mm² are to be avoided because their mechanical strength is not sufficient. The bodybuilder is responsible for the dimensioning.
• Negative and positive cables within a system must have the same minimum cross-section. • Current draw for 12-V equipment must be effected only via a voltage converter. • Drawing from only one battery is impermissible because unequal charges lead to overloading and
damage in the other battery. Under certain circumstances, e.g. for body-mounted equipment with a high power requirement (e.g. electrohydraulic liftgates) or in extreme climatic conditions, higher capacity batteries will be required.
Important notice If the bodybuilder installs larger batteries, the cross-section of the battery cable must be adapted to suit the new power draw.

Consumers must be connected in accordance with the following instructions.
• Terminal 15 power supply As a general principle, fit a relay that is controlled via terminal 15. The load must be connected to terminal 30 via a fuse. For information on further implementation, see terminal 30 power supply.
• Terminal 30 power supply for TGL new / TGM new In the case of a maximum load of up to 10 amperes, connect via a fuse on an additional fuse holder (see Fig. central electrical system); no fuse may be connected on existing fuse holders. In the case of a load >10 amperes, connect directly to the batteries via a fuse or to the fuse box on the battery box (see chapter III section 8.9.1).

In the case of a load >10 amperes, connect directly to the batteries via a fuse.
• Terminal 31 power supply Do not connect to the batteries, but rather to the ground points within (see Fig. ground point X6395/X6396 next to the central electrical system) and outside (ground point X100 right rear engine mount) of the cab. Observe the information in section 8.2.2 on ground cables.
Ground point behind the central electrical system: tightening torque (Ma) of 7 Nm + / - 1 Nm must be maintained.
Ground point of engine mount: tightening torque (Ma) of 9 Nm + / - 0.9 Nm must be maintained.
The negative cable of the body manufacturer may be connected to the negative terminal of the batteries if the battery terminal has sufficient space to connect the ground cable.

8.4.1 Notes on charging balance
TG new
A vehicle without additional electrical equipment requires approx. 50 A in order to supply the cab electronics and engine electronics, the exterior lighting and to recharge the batteries. All additional consumers must be supplied with the remaining current from the alternator.
In order to assess the electrical system it can be helpful to draw up a charging balance.
• Application case for positive charging balance:
During the loading process, 25 Ah (approx. 30 minutes of liftgate operation with the vehicle stationary and engine off) are drawn from the battery. The vehicle is subsequently driven for one hour to its destination (average engine speed 1200 rpm). During this trip the vehicle battery is charged with 50 Ah.
• Application case for negative charging balance
During the loading process, 25 Ah (approx. 30 minutes of liftgate operation with the vehicle stationary and engine off) are drawn from the battery. The vehicle is subsequently driven for 15 minutes to its destination (average engine speed 1200 rpm). During this trip the vehicle battery is charged with 12.5 Ah. The amount of current drawn from the vehicle battery by liftgate operation cannot be fully replaced during the short period for which the vehicle is driven.
As a basic principle, whenever additional electrical consumers are installed in the vehicle it must be ensured that the vehicle’s battery and alternator are dimensioned in accordance with the load. Beside bodies, additional electrical consumers also include electrical heaters and consumers that promote comfort.
Table 52-III lists the remaining charge current in dependence on the alternator installed and the respective engine speed in each case.
The sum of the current draw for all additional consumers for the period of vehicle operation must not exceed the charge-current values listed in Table 52-III. If over long periods more current is drawn from the vehicle battery than is fed to it, there is a risk that the battery will suffer permanent damage by deep discharge, for example.
The bodybuilder must ensure that the alternator and battery are adequately dimensioned for the vehicle operating profile envisaged.

MAN Guide to fitting bodies TG
Important notice The charging voltage of the alternators and vehicle electrical system charging converters installed in MAN vehicles can be up to 32 V.
The current drawn from the battery must not exceed the following maximum values.
• For periods of time ≤ 10 s: Currents up to 50% of the battery’s cold-start current
• For periods of time ≥ 10 s: Currents up to a maximum of 20% of the battery’s cold-start current
In general, it must be ensured that the vehicle is always able to start.
The cold-start current (Pos. 2 in Fig. Battery mark) is stated on the battery next to its rated capacity.
Fig.: Battery mark
1. Rated capacity 225 Ah 2. Cold-start current 1150 A as per EN standard 3. Rated voltage 12 V
In general, it must be ensured that the body does not increase the quiescent current of the vehicle. If drawing energy from the battery while the engine is not running is unavoidable (e.g. when the vehicle is being used for resting or due to liftgate operation), it must be ensured that the amount of energy drawn is replaced when the engine is in operation.
It must be noted that tapping the battery bridge for a 12-V supply is not permitted.
12-V consumers are to supplied exclusively by the vehicle’s 24-V electrical system and a correspondingly dimensioned DC/DC converter.

8.5 Batteries
TG new
The battery is connected to the vehicle electrical system via two battery poles. To protect against injury or damage during maintenance work, the main battery switch must be switched off.
When removing the terminals from batteries and operating the master battery switch, be sure to proceed in the following order:
• Switch off all loads (e.g. lights, warning flashing indicator) • Switch off the ignition • Close the doors • Wait for an after-run time of 60 seconds before disconnecting the batteries (negative terminal first).
The electrical battery master switch requires an extra 15 seconds.
You can find further information on this in the operator's manual of the vehicle in the section on practical advice for replacing the battery. With regard to second generation tachographs, it is essential that you observe chapter III, paragraph 8.10 “Smart tachograph” when disconnecting the batteries. Important notice When the engine is running:
• Do not turn off the master battery switch • Do not loosen or disconnect the battery terminals
From the end of 2016, the battery monitor will be introduced in series for vehicles whose cabs are equipped with a bunk and have 175Ah or 225Ah batteries.
It is necessary when relocating the battery box or extending the measurement line to ensure that the module is recalibrated.
Further information on the battery monitor is available on the MAN After Sales Portal.

8.5.1 Handling and maintaining batteries
TG new
Check batteries at regular intervals.
The battery tester DSS-7814 HD MAN, item number 08.78024-0005, must be used for testing batteries.Rapid-charge and jump-start devices must not be used for trickle charging as this could destroy control units. Jump-starting from one vehicle to another is permissible, provided that the instructions in the Operator’s Manual are followed.Observe the following when handling batteries:Table 53-III:
Standstill time
For a standstill time of more than 2 days:
➔ Switch off the main battery switch.
Open-circuit voltage never below 12.45 V before delivery
The open-circuit voltage must not fall below 12.45 V at any time prior to delivery to the customer.
Charge batteries at less than 12.6 V open circuit voltage. To ensure that the open- circuit voltage does not fall below 12.45 V by the next check, batteries that do not have an open-circuit voltage of at least 12.6 V when checked must be charged.
Always recharge batteries after they have been subjected to high load.
Regardless of the standstill time, always charge batteries if they have been subjected to heavy loads, for example after fitting or repairing a liftgate with subsequent functional test, or if the vehicle has been started/manoeuvred several times without being driven afterwards.
Vehicles must not be started or moved without batteries.
Batteries age very quickly if the battery voltage drops below 12.6 V for an extended period. If batteries should prove to be damaged or faulty at the vehicle handover to the customer, they will be charged back to the body manufacturer.
Further information on handling and maintenance of batteries can be found in TI 1140TA, which is available from MAN Service and the MAN After Sales Portal.

8.6 Lighting installations
TG new
Altering the lighting system means that the partial operating permit according to the directive UN ECE-R48 becomes void. This is the case especially if the arrangement of the lights is altered, or a light is replaced by one not approved by MAN.
The bodybuilder is responsible for adherence to legal requirements.
Observe the maximum load on the lighting circuits.
Fitting higher rated fuses than the corresponding ratings in the central electrics box is not permitted.
The following guideline figures are intended as maximums:

Reverse light 3x21W Note: "Preparation for spotlight, final cross member" for actuating additional lights can be ordered; use of MAN LED HL enables a higher additional load
Overloading the outputs results in the drivers switching off.
If lights are mounted that differ from the MAN factory equipment, the diagnostics and diagnostic thresholds may have to be adapted.
Where vehicles have been factory-fitted with LED rear lights, those lights can be replaced with rear lights (LED) specific to the body manufacturer. The rear lights must be equipped with a current pulse according to ISO 13207 for the turn indicators and brake lights. If ISO 13207 is not met for the brake light, diagnostics must be deactivated.
A conversion pack is also available for vehicles not factory-fitted with LED rear lights. In this case, before the conversion to LED rear lights the electronics structure must be modified by configuration.
The installation of LED lighting elements that are not approved by MAN is prohibited. It must be noted that MAN vehicles employ a ground cable: use of the vehicle frame as a return line is not permitted (see also Chapter III, Section 8.2.2 “Ground cable”).
Important notice Basic requirement of legislation for the design and installation of lighting and turn indicators:• ECE Regulation No. 48 (vehicles and trailers)

Following installation of bodywork the basic beam alignment of headlamps must be newly adjusted. On vehicles with headlamp levelling this must be performed direct on the headlamps because adjustment bythe regulator does not replace basic alignment on the vehicle. Extensions or modifications to the lighting system must be carried out in consultation with the nearest MAN Service outlet because it may become necessary to reparameterise the vehicle’s electronics using MAN-cats (see also Chapter III, Section 8.1.3).

8.7 Display and instrumentation concept
TG new
The combined instrument is incorporated into the control unit network by means of a CAN bus system. A fault is displayed in plain text directly in the central display or through a diagnostic memory entry. The combined instrument receives all the information that is displayed in the form of a CAN message. If additional functions are to be displayed (e.g. retrofit of a liftgate), this is included in the relevant special equipment or re-parametrisation is required. With the equipment version 0P2NA "Interface for data exchange with body, behind front panel and external engine intermediate speed control", it is possible to display body-specific messages in the vehicle display. A description of this can be found in the relevant interface description. It is not permissible for the body manufacturer to introduce their own functions in the central display or to tap signals on the rear of the instrumentation.

8.10 Smart Tachograph
TG new 1. A second generation of digital tachographs known as "intelligent tachographs" (or "smart tachographs") was introduced, in order to comply with the new EU Regulation No. 165/2014, the Commission Implementing Regulation EU 2016/799 Appendix IC and EN 16882:2016.
Any newly registered vehicle as of 15/06/2019 over 3.5 t in commercial use must be equipped with the new generation of digital tachograph.
The introduction of the smart tachograph comprises modifications to the following components:
• New KITAS 4.0 sensor • New KITAS seals • New tachograph: (ex works DTCO R4.0 or SE5000 R8.0) • DSRC module (Dedicated Short Range Communication) = short-range wireless interface so
authorities can read out the status of the tachograph • The stickers for statutory inspections (e.g. sections 57b and 57d in Germany).
2. The DSRC module must not be concealed. Make sure that the marked area in the Fig. Position DSRC module is not concealed
Ensure that there are no metal objects (e.g. name plates, stickers, anti-reflector foils or similar items) in front of or in the proximity of the DSRC module, as these could have an adverse effect on communication.
Fig.: Position DSRC module
Please note: A KITAS sensor that has already been taught-in can no longer be used after the replacement of a tachograph and must also be replaced.

Operation of the OMSI F.PTO is entirely independent of the driving clutch, however impacts arising during transient operation (“pump & roll”) are fed back through the drive line to the engaged driving clutch. Therefore damage may occur at that point.
Heavy impact loads can lead to damage to the multiple-disc clutch of the OMSI F.PTO, and can even lead to irreparable damage to the PTO itself..
The OMSI F.PTO is available with four different transmission ratios. The maximum permissible output torques for the respective transmission ratios are indicative values based on a non-uniformity value of 1, i.e for operation free of impacts and vibration.

It is always possible to operate the OMSI F.PTO even at connection to propshaft offset angles larger than those specified in Section 1.2 “Connection to propshaft at the PTO”. It is however essential that the relevant application is approved in advance by MAN. The limiting values specified by the propshaft manufacturer must not be exceeded.
The OMSI F.PTO is fitted with an integral brake. That means that when the OMSI F.PTO is deactivated the flange does not rotate even though the engine is running.

Information about activating the OMSI F.PTO
• When the vehicle is delivered, the OMSI F.PTO is in “Delivery Mode” and must be released beforebeing used for the first time. Instructions for this are contained in the operator's manual.
• The OMSI F.PTO can be operated when the vehicle is stationary and also when it is moving.
• Transmission locking to ensure the vehicle remains stationary during the application is not an optionthat is currently available
• The OMSI F.PTO is ready for operation as soon as the engine is running, but only at engine speedsgreater than 800 rpm and only when the input clutch is engaged may it be subjected to load. This issignalled in the information display of the F.PTO by the message “PTO ENGAGED”.
• If other clutches or disconnection points are present in the drive line of the body, these must bedisengaged during the OMSI F.PTO engagement process.
• Because of the very high mass moments of inertia, (for instance the drives to fans), an unloadedengagement of the OMSI F.PTO may in some circumstances be permissible at speeds as low as600 rpm. The agreement of MAN and special vehicle parameterisation is necessary for this.
• When the vehicle is stationary, power transmission to the PTO is completely independent of thedriving clutch.
When the PTO is being engaged, the values shown in the diagram below should be complied with. Under some circumstances, units such as fans with a mass moment of inertia higher than 10 kgm² may be coupled to the OMSI F.PTO. The agreement of MAN and special vehicle parameterisation is necessary for this.
Important noticeMinimum speed in operation : Do not let the engine speed drop below 650 rpm when the PTO is under load. To prevent the engine stalling and the dampers suffering damage, this value should be increased for applications with a high incidence of impacts or abrupt changes in loading.

Fig. XX6: OMSI F.PTO: Engagement speed and working speed
1) Engangement range
2) After consultation usable engagement range
3) Work space
4) Max. tolerance for work space
Provided the specified conditions are met, the OMSI F.PTO can be engaged at speeds of 800 - 1 000 rpm. If it is necessary because of the mass moment of inertia of the unit that is being driven to perform engagement at a speed less than 800 rpm, MAN must be consulted. Working speeds of 800 - 1 800 rpm require no prior consultation..
Combination with clutch-dependent PTOs
It is possible in principle to combine the OMSI F.PTO with other clutch-dependent PTOs on the end of the gearbox. However, the NTX/10 variants cannot be fitted in the lower position on vehicles with two front axles. The NH/4 variant can be fitted in the suspended position, but the pump geometry and the resulting installation space must be checked. In each case there is the risk of collision with the 2nd front axle.
Retrospective installation
Strengthened components are installed at many places on vehicles when they are individually factory-fitted by MAN with an OMSI F.PTO. In some circumstances it is therefore not possible to retrofit a power take-off to an existing vehicle, or to do so would entail the risk of damage. Therefore, before starting such a conversion, it is essential that consultations are held with MAN.
MAN Guide to fitting bodies Power take-offs
Spacings and clearances
A clearance of at least 60 mm must be maintained above the OMSI F.PTO..
After installation there must still be free access to the oil filler opening. Access must be sufficient that the oil filler plug can still be unscrewed, removed, and reinserted. The position is shown in the drawing below.
Fig. XX7: Position of the oil filler opening
The integration of the OMSI F.PTOs renders necessary the use of a special gearbox cross member; this cross member projects over the top edge of the frame.
Fig. XX8: Position of the gearbox cross member
A gearbox cross member optimised for the installation space is available for concrete pump mixers..
