Screw the Connector
Step 4: During off grid operation time, PE line at the BACK-UP end will remain to be connected with
the PE line at the power grid end inside the inverter. (Only applicable to market in Australia)
5.4.1 Earth Fault Alarm
This inverter complies with IEC 62109-2 clause 13.9 for earth fault alarm monitoring. If an earth fault alarm
occurs, the ring light on the inverter LED panel will be lit up in red and an error code <31> can be viewed on
the eSAJ Home App.
Note
：
The inverter cannot be used with functionally earthed PV Arrays.
5.4.2 External AC Circuit Breaker and Residual Current Device
Please install a circuit breaker to ensure the inverter is able to disconnect from grid safely. The integrated
leakage current detector of inverter is able to detect the real time external current leakage. When a leakage
current detected exceeds the limitation, the inverter will be disconnected from grid quickly.
The inverter does not require an external residual current device, as it has integrated with a RCMU. If local
regulations require the application of external residual current device, either type A or type B RCD is
compatible with the inverter. The action current of external residual current device should be 300mA.

WARNING
Dangerous to life due to electric shock when live components or DC cables are touched.
·
when the photovoltaic array is exposed to light, it supplies a d.c. voltage to the PCE.. Touching live DC cables results
in death or lethal injures.
·
DO NOT touch non-insulated parts or cables
·
Disconnect inverter from voltage sources.
·
DO NOT disconnect DC connectors under load.
·
Wear suitable personal protective equipment for all work.
