• Avoid any risk of mechanical shock caused by dropping objects onto the cell / mono-bloc or by dropping the cell / mono-bloc itself
• Avoid contamination of the lids by dust etc.
b) During storage period, checking the batteries voltage and applying maintenance charges to them is mandatory.
The average storage temperature determines the test and charges intervals:
• 20ºC: 6 months first time. Then, each 3 months.
• 30ºC: 4 months first time. Then, each 2 months.
Higher temperatures storage is not recommended.
In any case, if OCV (Open Circuit Voltage) measurement < 2,07 Vpc, consider a maintenance charge.
To avoid damage, the following general charging methods can be chosen. It is recommended to check for special instructions for each particular battery model.
Equalizing-charge as follows: 2.40Vpc Max. 20-30A / 100Ah depending on batteries model.
24 < t < 48h
The cells / bloc temperature must never exceed 45°C . If it does, stop charging.
Float charging, typically: 2,27Vpc. / 25ºC t > 48h
10.4 Mechanical Installation
The Outdoor Cabinet can be shipped in the following equipping stage:
• Subrack without equipped units
• Without batteries
• All internal cabling and Primary Network pre-connected
The procedure for anchoring the cabinet is as indicated hereafter:
• Open the doors of the cabinet for giving access to the cabinet bottom holes where the studs in the metal plate must be inserted.
• Lift the roof for giving access to the lifting eyes located on the internal part of the roof.
• Lift up the cabinet by means of those eyes on the internal part of the roof, and align the bottom holes with the threaded studs in the metal plate located on the basement.

Once the cabinet has been anchored to the threaded studs:
• Check the proper leveling of the structure, both horizontal and vertical, with a level or plumb line.
• Enter the grounding and power supply cables, the Secondary Network subscribers cables and the fiber optic cables towards the cables entry area, guiding them through the corresponding cable ducts, and fasten them properly.
10.5 Electrical Connections
The equipment has been designed to be directly powered from the external Mains supply (230 Vac).
Whenever any door of an area which contains a part which operates with a harmful voltage or which can be exposed to harmful voltages in the case of failure is open by the user, that potentially harmful part is protected from an eventual contact. The dangerous areas are labeled with an ENERGY HAZARD label.
The connection procedure must follow the sequential steps indicated below:
• Safety ground connection. See chapter 10.5.1
• Power supply connection. See chapter 10.5.4
• Transport signals connection. See chapter 10.5.6
• Subscriber lines connection. See chapter 10.5.7
10.5.1 General Cabling Inlet Rules Cables which are coming inside the cabinet must be led in according to Figure 64.
For keeping the IP Protection degree of the cabinet once the cables are passed through the cones, the cables must be tightly inserted through the plastic cones.
For that, and for each cone,
• the surface of the cone to be cut out must be smaller than the section of the cable to be inserted in it
• if more than one cable are to be inserted through one cone, this tightly insertion must be achieved by using silicone around the cables, for closing the gaps

10.5.2 General Cables Routing Rules As a general rule, the cabling will be guided without obstructing the handling or the viewing of the different cards or devices of the electronics equipment mounted in the cabinet.
The cabling will be also neatly arranged and fixed, so as to minimize the risk of a non-desired disconnection during the normal operation within the cabinet.
The cabinet is provided with several holes for the guiding of the cables between the different areas, Electronics, MDF, ODF, Batteries areas.

Table 29. Cabling Holes Allocation
Holes 14, 15, 19 & 21 in the cabinet are spare.
When the holes are provided with cones for the keeping of the IP-55 protection level, the same rules as in previous chapter apply.
10.5.3 Safety Ground Connection This is the first connection to be made, before any other connection, just after having anchored the cabinet.
Both 1 and 2 MLS outdoor cabinets have a safety ground cable which connects the Power Distribution Frame to the Safety Ground Terminal, located in the MDF area of the cabinet. See Figure 23.
Besides, the outdoor cabinets have another 10 mm2 cable which is connected to the Safety Ground Terminal on one end, and whose other end is to be connected to the Ground Stake located on the concrete basement, or close to it.
10.5.4 Power Supply Connection There are two main parts:
• 230 Vac Mains Power Supply Connection. See chapter 10.5.4.1.
• Batteries Connection. See chapter 10.5.4.2.
10.5.4.1 230 Vac Mains Power Supply Connection
According to EN 50160 – Power Quality Standard, the voltage fluctuation in Mains is 230 V ± 10%.
Proceed as follows:
- Let in the 230 Vac Power Supply cable through the appropriate hole in the base (see Table 29) of the cabinet and guide it to the Electronics area, to be connected to the terminals next to the Power Selector, which switches between the normal power and the Emergency Power.
- Remove the protection cover from the breakers box, located in the electronics area, in order to access the two terminals for power supply cable connection. The safety ground cable coming with the 230 Vac Power Supply cable should be connected to the Safety Ground Terminal in the MDF area of the cabinets.
See Figure 23 & Figure 24.

10.5.4.2 Batteries Connection For the battery pack installation, proceed as follows:
• Put the batteries on its support in the battery area of the cabinet
• Connect the cables coming from the Rectifier Unit to the batteries
As an example, document 3EC 44319 0020 BCZZA shows the recommended operation system for batteries 3AM 20221 AMAA in the 2 MLS cabinet.
See Figure 23 & Figure 24.
10.5.5 Insertion Procedure of a Board with a Big Amount of Rear Connectors
Due to the big amount of connectors, and thus a lot of connection pins at the rear of some boards, to be connected at the back panel, special care should be taken during the insertion process of GEB-3B and/or other cards with similar amount of rear connectors.
It is highly recommended to do the process in three steps:
• Do a first insertion of the card with a correct positioning of the extractors in the subrack profiles,
• Press once more over the front face of the extractors
• Check the position of the board
To see whether the board is correctly inserted, check that:
• the leds of the front plate are light,
• the internal face of the front plate is in contact with the front face of the subrack front profiles; see Figure 66
• for the bottom part, the top of the subrack profile must be inserted in the groove of the extractor; see Figure 66
• for the top part, similar situation
• the front face of the extractor is located at right angles with the top face of the cables guide of the front plate, and parallel to the front plate itself; see Figure 66.

10.5.10 Subscribers Lines Connection
10.5.10.1 Subscriber Cables Inlet The subscribers cables coming through the cabinet inlet plate (see Figure 64) must be fixed at the MDF inlet by using the cable clamps as shown in Figure 68.
The clamps can be adjusted to the incoming cable by means of their screws.
For their screen to be connected with Ground, the cables must have a length without cover. In this way the screen can be pressed by the clamps and then connected with Ground.
Figure 68. MDF Inlet Cables Distribution
10.5.10.2 Subscribers Cables between Litespan and the MDF The whole cabling coming from the Electronics area towards the Main Distribution Frame (MDF) area is provided already wired up from the factory, therefore the equipment is delivered with a fixed pre-set configuration.
Note that the cabling is prepared for a Line card in each slot. So, if not all line cards are equipped, each one must use its own dedicated cable.
The cables not used in a particular configuration must be left fixed at the front lateral parts of the subrack, prepared for being used in a future, and not interfering with other cabling or with the air fluxes through the subrack.
The MDF, located in the right part of the cabinet, is mounted on a fixed structure which allows an easy access to all existing connection modules. The MDF has two parts: Primary (Upper part of the MDF) and Secondary (Lower part of the MDF).
Each connection module has:
• Primary Connection Module: 32 positions (16 pairs)
• Secondary Connection Module: 20 positions (10 pairs)

It is divided in two sections "a" (upper part) and "b" (lower part):
• In section "a" (upper one) the signals coming from MLS (Primary Network) or Subscriber Lines (Secondary Network) are connected
• In section "b" (lower one) is used for the associative connections between Primary Network and Secondary Network sides,
In any case, a special tool is required to connect/disconnect the wires in the module.
Figure 69. MDF Primary Connection Strip
The aspect of the Secondary side connection strip is similar to this figure, for 10 pairs instead of 16.
For meeting the ITU K.45 Recommendation, “Resistibility of Telecommunication Equipment installed in Access and Trunk Networks to overvoltages and overcurrents”, it is required to install Overvoltage protections on each subscriber line
They can be installed either on Primary side or in Secondary side (where the connection modules allow it), by means of adequate cartridges provided with the protections mounted on the connection modules.
