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.
• Install one AC circuit breaker for each inverter. Multiple inverters cannot share one AC circuit
breaker.
• 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:
Inverter model
GW5000-MS
GW6000-MS
GW7000-MS
GW8500-MS
GW10K-MS
Select and Install RCD depending on local laws and regulations.Type A RCDs (Residual Current
Monitoring Device) can be connected to the outside of the inverter for protection when the DC
component of the leakage current exceeds the limit value. The following RCDs are for reference:
Inverter model
GW5000-MS
GW6000-MS
GW7000-MS
GW8500-MS
GW10K-MS
• 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.
