IMPORTANT  SAFETY  INSTRUCTIONS

SAVE THESE INSTRUCTIONS! 

This manual contains important 

instructions to follow during installation and maintenance of the 
APsystems photovoltaic grid-connected inverter (microinverter). To 
reduce the risk of electrical shock and ensure the safe installation 
and operation of the APsystems microinverter, the following symbols 
appear throughout this document to indicate dangerous conditions and 
important safety instructions.

WARNING:

 This indicates a situation where failure to follow 

instructions may cause a serious hardware failure or personnel danger 

if not applied appropriately. Use extreme caution when performing 

this task.

NOTE:

 This indicates information that is important for optimized 

microinverter operation. Follow these instructions closely.

SAFETY INSTRUCTIONS 

 

Do NOT disconnect the PV module from the APsystems 

microinverter without first disconnecting the AC power.

 

 

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  

PV –  array.

 

Be aware that the body of the APsystems microinverter is the heat 

sink and can reach high temperatures. To reduce risk of burns, do 

not touch the body of the microinverter.

 

Do NOT attempt to repair the APsystems microinverter. If it fails, 

contact APsystems Customer Support (844-666-7034) to obtain 

an RMA number and start the replacement process. Damaging or 

opening the APsystems microinverter will void the warranty.
