INSTALLATION, CONNECTION AND ENERGIZATION
10.3 ENERGIZATION, START-UP AND SAFE DE-ENERGIZATION
This chapter provides the following information:
It is mandatory to connect the inverter to a protection ground (PE).
How to check and prepare the inverter before powering-up.
How to power-up and verify the energization success.
How to operate the inverter when installed according to the standard project (refer to the
page 10-13
and the attached electric project).
How to de-energize the inverter safely.
10.3.1 Pre-power Checks
The inverter must have already been installed according to the
Even when the inverter electric project is different from the suggested one in the attachment, the following recommendations are applicable.
DANGER!
Always disconnect all the power supplies before making any connections.

Although the inverter commands the opening of the input circuit breaker, there is no guarantee of its opening and neither
that no voltages are present.
DANGER!
Débranchez toujours toutes les alimentations avant d'effectuer des branchements.
Bien que l'onduleur commande l'ouverture du coupe-circuit d'ouverture, il n'y a pas de garantie qu'il s'ouvre ni que des
tensions sont présentes. Pour ouvrir les armoires moyenne tension, suivez toutes les procédures de mise hors tension
de sécurité.
In order to open the medium voltage cabinets, follow all the safe de-energization procedures.
1. Check if all the power, grounding and control connections are correct and tightened.
2. Clean the inverter internally, remove all packing material and installation residues from within the MVW01 cabinets.
3. Check all motor connections and verify whether its voltage, current and frequency match the inverter specifications.
4. If it is possible, decouple the motor mechanically from the load. If the motor cannot be decoupled, then make sure that rotation in any
speed direction (Forward or reverse) is not hazardous to people or to the machine.
5. Close and lock the panel doors.
