Connecting power cables

Connect power cables between the battery modules and the higher-level system via
busbars.

CAUTION

When connecting power cables, pay attention to these precautions:

• Never connect battery modules in series. They must be connected in parallel.

• Make sure that the higher-level system is off before connecting power cables

to it.

• Make sure that all the power cables are of equal length. If some cables are

longer than others, the difference in length may cause different electrical re-

sistances and consequently voltage imbalances between the battery modules.

• The total extension length of the power line from a battery module to the

higher-level system must not exceed 5 m.

• Never short-circuit the busbars that connect the battery modules and the

higher-level system.

• Make sure that the polarities are correctly connected.
