6.5 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 red color LED indicator will light up. At the same time,
the error code 38 will be sent to the GSMARTE. (This function is only available in
Australia and New Zealand)
7 Commissioning
Risk of injury due to incorrect installation
• We strongly recommend carrying out preliminary checks before commissioning
to avoid possible damage to the device caused by faulty installation.
7.1 Electrical checks
Carry out the main electrical tests as follows:
① Check the PE connection with a multimeter: make sure that the inverter’s exposed
metal surface has a ground connection.
Danger to life due to the presence of DC voltage
• Only touch the insulation of the PV array cables.
• Do not touch parts of the sub-structure and frame of PV array.
• Wear personal protective equipment such as insulating gloves.
② Check the DC voltage values: check that the DC voltage of the strings does not
exceed the permitted limits. Refer to the Section 2.1 "Intended use" about
designing the PV system for the maximum allowed DC voltage.
③ Check the polarity of the DC voltage: make sure the DC voltage has the correct
polarity.
