6.4 Connecting the AC Output Cable

• Do not connect loads between the inverter and the AC switch directly connected to the
inverter.
• The Residual Current Monitoring Unit (RCMU) is integrated into the inverter. The inverter
will disconnect the utility grid rapidly once it detects any leak current over the permissible
range.
An AC circuit breaker shall be installed on the AC side to make sure that the inverter can safely
disconnect the grid when an exception happens. Select the appropriate AC circuit breaker in
compliance with local laws and regulations. Recommended AC circuit breakers:

GEP3.5-1-10
GEP3.6-1-10
GEP4.2-1-10
GEP4.6-1-10
GEP5.0-1-10
A type A RCD(Residual Current Device) shall be added to protect the equipment when the DC
component of the leakage current exceeds limits. Recommended RCD specifications:

GEP5.0-1-10
Install one AC circuit breaker for each inverter. Multiple inverters cannot share one AC circuit
breaker.
• Pay attention to the silkscreens L, N, PE on the AC terminal. Connect the AC cables to
the corresponding terminals. The inverter may be damaged if the cables are connected
inappropriately.
• Make sure that the whole cable cores are inserted into the AC terminal holes. No part of
the cable core can be exposed.
• Make sure that the cables are connected securely. Otherwise, the terminal may be too hot
to damage the inverter when the inverter is working.
