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.
The system start-up is completely guided; the indications available by the touch screen allows the
complete comprehension of the various steps and helps the operator in performing the requested
operations in the correct sequence.
However, all the sectioning devices must be mandatorily manoeuvred under the supervision and
control of engineers who are qualified to operate on electrical circuits.
Use qualified personnel only
Any electrical manoeuvre must be carried out by qualified and trained personnel.
