4.4Battery Breaker Test

1.Before turning on the battery circuit breaker, confirm with a multi-meter that the battery is not reverse-connected.

2.When connecting the battery, be careful not to short the two battery terminals.

3.When connecting two batteries, be careful to avoid battery mutual charging due to unequal terminal voltages of the two batteries.

4.5BCU Test

The BCU can connect to a single battery via suitably sized cables from the

Distribution Unit.

The BCU can connect to up to five battery strings via suitably sized cables.

The user can route the battery cables via the left hand side and via the right hand side of the BCU. A maximum of 7 cables can be routed via the left hand side of the BCU and a maximum of 5 cables via the right hand side of the BCU.

The user can mount the BCU 15mm or more above a Front terminal battery. Care shall be taken to connect the battery to the BCU via cables in this orientation.

The user can safely connect battery cables on a live system with only front access. BCU can be partially slid out in order for this to be achieved.

The user can safely install or replace a battery circuit breaker on a live system with only front access. BCU can be partially slid out in order for this to be achieved.

4.6 Load Breaker Test

Before connecting load to the system, check with a multi-meter if the connection polarity of the load and the power system is correct and the voltage is normal.

1.Close the load MCB, DC power should be fed to the load;

2.Adjust the system parameters through the SCU, and make sure that the information viewing and output control functions are normal.
