1.1 Safety Instructions
Only qualified professionals should install and/or replace APsystems Microinverters.
Perform all electrical installations in accordance with local electrical codes.
Before installing or using the APsystems Microinverter, please read all instructions and cautionary markings
in the technical documents and on the APsystems Microinverter system and the solar array.
Do NOT disconnect the PV module from the APsystems Microinverter without first disconnecting the AC
power.
Be aware that the body of the APsystems Microinverter is the heat sink and can reach a temperature of 80°C.
To reduce risk of burns, do not touch the body of the Microinverter.
Do NOT attempt to repair the APsystems Microinverter. If the micro is suspected to be faulty, please contact
your local APsystems Technical Support to start troubleshooting and obtain a RMA (Return Merchandise
Authorization) number to start the replacement process if needed. Damaging or opening the APsystems
Microinverter will void the warranty.
Caution!
When connecting a microinverter, it is recommended to first connect the AC Bus cable to the ground then
connect the AC connector to ensure proper earthing of the micro-inverter, then do the DC connections. When
disconnecting a microinverter disconnect the AC by opening the branch circuit breaker first but maintain the
protective earthing conductor in the branch circuit breaker connected to the microinverter, then disconnect
the DC inputs.
Please install AC breakers on the AC side of the inverter.
