4 Installation

All ACTURA 48 701z Power Systems must be installed as per instructions of this chapter.

4.1 Unpacking

1. The Power System is factory tested and inspected. Upon receiving the Power System, make sure that all the boxes listed in the shipping specification are delivered, and that they have the correct type numbers.

2. The final unpacking of each unit should not be done until just before the installation. There might be loose parts packed with the units (e.g. screws) and to prevent losing them, the unpacking should be done when installing the equipment.

3. The Power System is delivered completely wired and configured to accept up to 5 rectifier modules (configuration dependant).

4. The Rectifier modules are separately packed, and the actual quantity to be installed depends on the load requirement and the battery recharge requirement.

5. When unpacking the Rectifier modules from the carton, first visually inspect them for damage that might have occurred during transportation. If a Rectifier module appears to have been physically damaged, do not install it into the Power System or attempt to switch it on. Damaged equipment should be returned to Emerson (refer to Failure Report chapter).

4.2 Cabinet Mounting

The System Cabinet can be fixed to the floor and to the wall by means of L-shaped brackets (refer to Figure 4.1). During transportation, both brackets are mounted at the top-rear of the cabinet.

Recommended minimum circuit breaker rating in the distribution board for 3-phase connection is > 40A per phase for ACTURA 48 701z. For the three-phase (3+N+PE) connection, a 5-core cable rated in accordance with the circuit breaker in the Main Distribution Board and Local Standards/Directives must be used to provide AC supply to the Power System. After the AC input supply cable has been terminated, it must be strapped to the cable strap point provided on the AC Distribution where the cable exits the enclosure (refer to Figure 4.3).

4.6 DC Load Output Connections

Fig 4.4: Example of DC load distribution The standard DC distribution caters for termination of Priority loads and Normal loads. The Normal Load “NL” circuit breakers (also known as Low Priority “LP”) and Priority Load “PL” circuit breakers (also known as High Priority “HP”) are grouped as per Figure 4.4. The number and grouping of circuit breakers is configuration dependant. The purpose of the circuit breakers may be indicated on the “Load Distribution Label” (if applicable). The positive load connections are to be terminated on the common positive busbar at the back of the load circuit breakers. The positive load cables must be connected to the tunnel terminals or M8 bolts (refer to Figure 4.5) and tightened. Maximum recommended cable size is 50mm², minimum recommended cable size is 2.5mm², torque of 4 to 5Nm. The negative load connections are made to the relevant distribution circuit breakers. Maximum recommended cable size is 50mm² (circuit breaker dependant), minimum recommended cable size is 2.5mm². The recommended torque for circuit breaker terminals is 2 to 3 Nm.

Fig 4.5: Termination of negative load cables

The System Controller monitors the status of the distribution circuit breakers. For monitoring purposes, each circuit breaker is assigned with a sense wire (circuit breaker sense wire), which must be connected to it. The circuit breaker sense wires must be connected to the load circuit breakers together with the negative load cables. The circuit breaker sense wires are colour coded and grouped into 5 banks. Black: Group 1 – circuit breaker position 1, 2, 3, 4 and 5 Brown: Group 2 – circuit breaker position 6, 7, 8, 9 and 10 Red: Group 3 – circuit breaker position 11, 12, 13, 14 and 15 Orange: Group 4 – circuit breaker position 16, 17, 18, 19 and 20 Yellow: Group 5 – circuit breaker position 21, 22, 23, 24 and 25. Note that each group of circuit breaker sense wires are equipped with a spare, 6th wire, which is to be used as a replacement in an unlikely event of sense wire failure. All un-used sense wires must be placed into the trunking, located behind the circuit breakers. The DC output cables should be strapped to the cable strain relief strap points, provided at the back of the Distribution sub-assembly. These cables should be then routed through the top of the battery cabinet (holes are provided). Cable size shall be selected in accordance with circuit breaker rating and allowable voltage drop. The maximum recommended voltage drop is 400mV. To meet the voltage drop, the following formula could be used as a guideline for selecting the minimum cross-sectional area required for the load cables: Amin [mm2] = 0.05 x L [m] x I [Adc] Amin Minimum cross-sectional area of load cable in mm2 L total length of positive and negative cable in meters I circuit breaker rating in amperes DC.



4.7 Outgoing Alarm Connections Eight potential free relays for the purpose of outgoing alarms are provided on the User Interface Board, located above the System Controller (refer to Figures 2.1 and 3.1). Every relay output has N/C (normally closed) and N/O (normally-open) contacts.

4.9 Battery Installation The battery distribution cabling is pre-wired as standard. The system cabinet comprises four battery shelves. The battery space available for each string in standard configuration is: 540mm (W) x 570mm (D) x 320mm (H). Each battery shelf is designed to accommodate four (VRLA) 12V-battery blocks with front terminals. Four 12V-battery blocks are always connected in series. Suitable links (not provided) should be used for connecting battery blocks in a string. The front terminal battery blocks must be placed next to each other (refer to Figure 4.8). Repeat the following procedure for each battery string installed. Battery string 1 is always at the bottom of the cabinet (refer to Figure 1.1). 1. Switch all four battery circuit breakers off (located next to each battery shelf). 2. Remove the Battery compartment cover by removing the four M6 screws (if

applicable). 3. Place all four 12V battery blocks on a shelf. 4. The negative battery cable, located on the left-hand side of the battery cabinet,

must be connected to the negative battery pole. 5. The positive battery cable, located on the right hand side, must be connected to

the positive battery pole. 6. Please consult the Battery manufacturer for the correct torque on the battery

terminals. 7. Replace the Battery compartment cover (if applicable). Battery temperature sensors are factory fitted and do not require installation.



The String Voltage Equalisers are optional items (configuration dependant).

Fig 4.7: String Voltage Equaliser Battery Sense Terminal Ring Some system configurations offer more advanced battery management (addition of SM BAT unit for block voltage and individual string current monitoring). In such instances, for the Power System to be able to perform such advanced battery management, the battery sense wiring and the terminal rings must be mounted on the battery poles. A set of battery sense wires and terminal rings must be attached to each installed battery. Each wire in a set is marked, indicating the required connection to the specified 12V battery block. The 12V battery blocks in a string are numbered from 1 to 4. The block connected to the positive (red) battery wire is Block 1, while the one connected to the negative (blue) battery wire is Block 4.
