3.12 BATTERY/LOAD DISTRIBUTION MODULE
The battery/load distribution module is supplied with a standard number of battery strings pre-wired. Optional extra
battery or load connections may also have been supplied and pre-wired from the factory as ordered. Servicing fuses,
circuit breakers or adding optional battery/load connection kits after initial installation and commissioning requires
that the lid of the battery distribution module be removed and top access can be gained. The lid is held in place by
two M3 screws at the front and will slide forward out of the Power shelf once the screws are removed. If top access
cannot be gained, the entire module can be removed from the front after disconnecting and isolating the battery/load
connections and removing the single M5 mounting screw at the rear.
To add a battery string kit, mount the circuit breaker, DC current transducer, output bus bar and wiring in the next
logical battery number position as shown in Figure 3.14. Connect the current transducer signal cable to the
appropriately labeled connector on the circuit board. Finally, make sure the jumper link for the same numbered
battery/load circuit alarm is linked for “BAT”. (see Figure 3.15).
To add a load connection kit, connect the DC bus side of the circuit breaker directly to the M6 stud on the DC bus
side of the LVDS. Starting with the “Battery 4” position, mount the output bus bar, circuit breaker and wiring. Set
the jumper link for the same numbered battery/load circuit alarm to “LOAD”. (see Figure 3.15).
Note: the above connection information is relevant when the LVDS is a battery disconnect. If the LVDS is a load
disconnect, the DC bus side wiring of the circuit breakers is reversed such that the battery connections come off the
DC bus side of the LVDS, while the load is taken off the LVDS common bus bar. Diode V27 in the battery
distribution module must be replaced with a shorting link for the LVDS to work as a load disconnect.
