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.

4.5 BCU 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

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.
