External Battery Cabinet (EBC) installation procedure
The installation procedure is as follows:
1.
The EBC is recommended to place next to the UPS unit.
Note!
Do not place EBC on the UPS unit.
2.
The required minimum distance for UPS unit and EBC is ten millimeters, which is also
required distance between two EBCs.
3.
Turn F1 battery breaker from the UPS unit in OFF position.
4.
Check that the circuit breaker F3 of the EBC is in the OFF position. To minimise safety risk
remove one of the cable (+ or -) from battery string to break a battery circuit.
Battery cables can be accessed by removing a plastic front cover and a metal hatch behind
the plastic cover. Do not remove the safety wire of the circuit breaker before all the wires
are connected and the installation of the whole system is ready. 
Remove plate A on the
rear side of the EBC to connect cables to EBC’s terminal block X6. Bring cables outside
from the EBC by removing the cover plate B. Place the plate A back to the original position
and connect the cable clamp to the place of the cover plate B.
