3.4 Electrical Connection
You must comply with the connection requirement of local
regulations.
The inverter is integrate with an RCMU according to VDE0126-
1-1/A1. It monitors residual current from the solar module to grid
side of inverter. The inverter can automatically differentiate
between fault current and normal capacitive leakage currents.
3.4.1 Connection to grid (AC side Connection)
A Check the grid (utility) voltage and frequency at the
connection point of the inverter. It should be 230VAC (or
220VAC), 50/60Hz, and single phase.
B Disconnect the breaker or fuse between PV-Inverter and utility.
C Connect the inverter to the grid as follows:
` Switch off the AC Breaker.
` Disassemble female connector of the AC wire connector
and connect AC wires to connection socket as indicated.
