Connection Steps
Grid Connection
Ø
X3 series inverter are designed for three phase grid. Rated grid voltage is 230V,
frequency is 50/60Hz. Other technical requests should comply with the
requirement of the local public grid.
Micro-breaker should be installed between inverter and grid, any loads
should not be connected with inverter directly.
a) Check the grid voltage and compare with the permissive voltage range (refer
to technical data).
b) Disconnect the circuit-bricker from all the phases and secure against re-
connection.
c) Trip the wires:
- Trip all the wires to 52.5mm and the PE wire to 55mm.
- Use the crimping pliers to trip 12mm of insulation from wire ends as below.

d) Separate the AC plug into three parts as below.
- Hold the middle part of the male insert, rotate the back shell to
loose it, and datach it from male inset.
- Remove the cable nut (with rubber insert) from the back shell.
e) Slide the cable nut and then back shell onto the cable.
f ) Insert the tripped end of each five wires into the appropriate hole in the
male insert, and then tight each screw (to tight each wire in place).(Use
the accompanying inner hexagon spanner)
g) Tighten the screw of the back shell and the male insert.
h) Tighten the screw of the back shell and the cable nut.
I) Align the groove of male terminal with the convex of female terminal ,
then tighten the bush in male terminal.
