Notes:
(1) 24 Vdc wiring: use shielded cables and keep them distant from power and command wiring.
(2) 220 Vac wiring: keep it distant from the power wiring.
(3) Example in 220 Vac. See the project.

Figure 6.10: Connections of the inverter input contactor for situations where it is supplied separately
NOTE!
The connection strips of Figure 6.9 on page 6-12 and Figure 6.10 on page 6-13 (X10 and X12) may
change according to the project. Always refer to the project that comes with the product.
ATTENTION!
The input circuit breaker must only be closed by the inverter, otherwise the transformer and the
inverter may be damaged.
DANGER!
Although the inverter commands the opening of the circuit breaker, there is no guarantee of its
opening. In order to open the medium voltage cabinets for maintenance, follow all the procedures of
safe de-energization (refer to the
Item 6.3.4 Safe De-energization Instructions on page 6-17 ).
DANGER!
Bien que l’onduleur commande l’ouverture du coupe-circuit, il n’y a pas de garantie qu’il s’ouvre. Afin
d’ouvrir les armoires moyenne tension pour la maintenance, suivez toutes les procédures de mise
hors tension (élément
Item 6.3.4 Safe De-energization Instructions on page 6-17 ).
6.2.3 Low Voltage Auxiliary Supply
Control column power supply nominal voltage selection
An auxiliary voltage supply (220 V-480 V) should be available in the installation. This voltage must be wired to the
terminal strip present in the control column. The command transformer (T1) taps must be selected according to
the available auxiliary voltage. For more details, refer to the MVW3000 electrical project.
