10.2 Start-Up Procedure
EPO push-button and phase rotation
Before switching the UPS on, make sure that:
1) the emergency power off “EPO” push-button, if installed, is not pressed. If not, press it back
to the rest position;
2) the input and output phase rotation is correct.
Circuit breaker BCB
Do not close the battery breaker BCB before it’s required by the front panel. Serious damages
to the UPS internal parts and/or to the battery may occur.
Wiring of the auxiliary contacts
Carry out a proper electrical installation by wiring the auxiliary contacts of the external manual
bypass, output and battery isolators to the dedicated terminals on board the UPS. This will
allow the control logic to acquire the status of the switches and guide the operator during the
start-up and manual bypass procedures.
