Figure 6.11: Auxiliary power supply
6.3 ENERGIZATION, START-UP AND SAFE DE-ENERGIZATION
This section provides the following information:
„
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 Section 6.2 ELECTRICAL
INSTALLATION on page 6-10 and the attached electric project).
„
How to de-energize the inverter safely.
6.3.1 Pre-power Checks
The inverter must have already been installed according to the Chapter 6 INSTALLATION, CONNECTION AND
ENERGIZATION on page 6-1 . 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 cubicle, 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 de l'armoire d'entrée, il n'y a aucune garantie de son
ouverture et ni qu'aucune tensions sont présentes.
In order to open the medium voltage cabinets, follow all the safe de-energization procedures.
