AC cable with L1, L2, L3, N wires and an external PE wire
WARNING!
To avoid shock hazard conditions, the PE wire must be connected to the
inverter before connecting the AC wires.
Use AC line wires with a maximum of 120 mm
2
cross section (For inverter models
SE50K to SE80K, use 95 mm
2
)
Use PE wire with a maximum 70 mm
2
cross section (For inverter models SE50K to
SE80K, use 50 mm
2
).
Use a PE wire with outer diameter of 9 to 16 mm (wire with insulation).
Use AC gland supports a cable of 30 - 50 mm in diameter.
CAUTION!
Over-current protection for the AC output must be provided by the installer.
Chassis Grounding
If required, ground the units as described in the following figure using a grounding
cable, a grounding screw, two washers, a ring terminal and a serrated washer. Connect
the grounding cable to the grounding point on either side of a unit and to either the
mounting hole or grounding screw. You can connect grounding to the Synergy
Manager and to each of the Synergy Unit, as required.
