PVP250kW & PVP260kW Inverter

Installation & Operation Manual

PRUDENCE

An d’éviter des surtensions inacceptables de CA lorsque l’onduleur est

branché, assurez-vous que la valeur de l’impédance aux points de connexion

au réseau public est la plus basse possible. Une faible valeur d’impédance

permet un fonctionnement plus efcace de l’appareil.

The inverter is connected to the electrical grid using four wires:

• Phase A voltage

• Phase B voltage

• Phase C voltage

• Ground

Do NOT connect a neutral wire to the WYE point of the isolation transformer.

The four AC termination busbars for phases A, B, C and ground are located in the lower

right of the AC panel. Refer to Figure 4-2. The phase busbars are vertically mounted and

the ground busbar is horizontally mounted at the bottom of the cabinet. Each busbar has

seven rows of two 3/8” diameter holes, spaced 1” apart vertically.

The AC connections must be made through the user selected gland plates (plates and

dimensions are shown in
