This battery cubicle shown is an example only, given that characteristics of these cubicles vary greatly from one cubicle to another:
◗remove the terminal shield from the battery circuit breaker QF1 to make the connections to this circuit breaker;
◗in the case of installations having several battery cubicles, the connections to be made between cubicles are
Important note:
◗the cubicle is supplied with a fixture locking circuit breaker QF1 in the open position. Do not remove this fixture before first startup: accidental closing of QF1 will power up the downstream circuits which could be hazardous for personnel and permanently damage the battery by deep discharge;
◗connections between battery cubicles should be made in compliance with applicable regulations: take all protective measures associated with working on live equipment and in particular use only qualified personnel equipped with gloves, protective goggles, insulated tools, etc. Connection of cables through lugs to copper terminals
