【
Procedure of Connecting AC Cables
】
Step 1 : Remove an appropriate length of the jacket and insulation layer from the AC
output cable using a wire stripper, as shown in Figure 5.5.
Figure 5.5 Stripped length (unit: mm)
Step 2 : Insert the exposed core wires through nut of AC terminal, sleeve in the
intermediate, L terminal of line wire, N terminal of neutral wire, into E terminal of
Earth Wire, tighten the screw. The required torque is 0.8 N.m. After fixing the cables,
tighten the nut and sleeve in the intermediate, as shown in Figure 5.6.
NOTE
Install an independent circuit breaker between inverter and grid
BEFORE all connections. Make sure inverter will be safely
disconnected from the grid in all circumstances.
It is recommended to use certified 250Vac/30A(for PV-5000S-
V/PV-5000S-HV) or 250Vac/20A(for PV-3000S-V/PV-3600S-V)
circuit breakers.
WARNING
An independent circuit breaker must be installed on the AC side
of each inverter to ensure that the inverter can be safely
disconnected from the power grid.
WARNING
Do not connect loads between the AC output terminals of the
inverter and circuit breaker.
