Ac Connection - Epcom EPIG7K Manual

5.5 AC Connection

WARNING !
Ensure that electrical connections are in compliance with the local
national and local standards.
WARNING !
The uncharged metal parts in PV power generation systems consist of
PV module bracket, the metal case of the inverter, which should be
grounded reliably. The grounding pole should meet the standard
requirements.
The grounding parts of multiple inverters and PV arrays should be
connected to the same grounding bus, building a reliable equipotential
connection.
Wiring on the AC side
1. Pass the appropriate length of cable through the waterproof connector cap and shell.
Strip the cable insulation about 10 mm (As shown in the figure below).
2. Fix L, N and PE wires to the corresponding AC terminals with a screwdriver and
ensure that the PE wire is properly grounded (As shown in the figure below). (It is
recommended to use soft copper core cables for uses)
3. Insert the shell into the AC terminal, hear a sound of "click", then tighten the
waterproof connector cap.
4. Insert the AC connector into the AC output terminal, then turn the AC connector
clockwise until hear a slight sound of "click", which indicates that the connection is in
place (As shown in the figure below).
CAUTION
According to the requirement of EN50178, the right side of the
inverter has a second earth terminal, which can be connected by the
combination screws M4 × 8 with flat pad and spring pad.
