Installation Environment Requirements
The installation environment must be free of in ammable or explosive materials.
Install the device away from heat source.
Do not install the device at a place where the temperature changes extremely.
Keep the device away from children.
Do not install the device at daily working or living arears, including but not limited to the following
areas: bedroom, lounge, living room, study, toilet, bathroom, theater and attic.
When installing the device at the garage, please keep it away from drive way.
Keep the device from water sources such as taps, sewer pipes and sprinklers to prevent water seepage.
The product is to be installed in a high tra c area where the fault is likely to be seen.
Note: When installing outdoors, the height of the device from the ground should be considered to
prevent the device from soaking in water. The speci c height is determined by the site environment.

External AC Circuit Breaker and Residual Current Device
Please install a 4P circuit breaker to ensure the inve er is able to disconnect from grid safely.
The inve er is integrated with a RCMU, however, an external RCD is needed to protect the
system from tripping, either type A or type AC RCD is compatible with the inve er.
The integrated leakage current detector of inve er is able to detect the real time external
current leakage. When a leakage current detected exceeds the limitation the inve er will be
disconnected from grid quickly, if an external leakage current device is connected, the action
current should be 300mA.
