PV Input Cable
Safety Precautions - AC Output Cable
• Do not connect loads between the inverter and the AC switch directly connected to the
inverter.
• An AC circuit breaker should be installed on the AC side to make sure that the inverter can
safely disconnect the grid when an exception happens. Install one AC circuit breaker for
each inverter. Multiple inverters cannot share one AC circuit breaker. Select an appropriate
AC circuit breaker in compliance with local laws and regulations.
• The residual current monitoring unit (RCMU) is integrated into the inverter. When the
leakage current exceeds the allowable limit, the inverter will disconnect from the grid
quickly.
• When the inverter is powered on, the BACK-UP AC port is live. Power off the inverter first
if maintenance is required for the loads connected with BACK-UP ports. Otherwise, it may
cause electric shock.
Connect a Residual Current Device (RCD for short) based on local laws and regulations. Type A
RCDs 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:
No. Inverter Model
1 GW100K05-ETC
2 GW100K06-ETC
3 GW100K07-ETC
4 GW100K05-BTC

6 GW100K07-BTC
• Pay attention to the L1, L2, L3, N and PE terminals. Connect the AC cables to the
corresponding terminals. The inverter may be damaged if the cables are connected to the
wrong terminal.
• Ensure that the whole cable cores are inserted into the terminal holes. No part of the cable
core can be exposed.
• Ensure that the cables are connected securely. Otherwise it will cause damage to the
inverter due to overheat during its operation.
• Connect the ON-GRID cable before BACK-UP cable when connecting the AC cables.
