AC power supply and ground
The following images indicated how and where to make the connections of AC input .
NOTICE
Use only the bottom panel to route the AC cables.
Each charge line requires its own AC power supply.
The terminal block that appears in the area immediately above the entrance allows the connection of
each charge line. The gray terminals are used to connect each of the phases, the blue connects the
neutral and the green and the yellow connects the ground.
In some configurations, when there is a surge protector, the power supply connection will be made
directly on this component. The connection will be made in the upper part of the protector, in the
terminals enabled for it, next to the terminals of the general installation. The following image indicates
in detail this connection.
In this case, the earth connection must be made directly on the ground plate, located on the lower side
of the equipment:
