1.Important Safety 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 Specifications subject to change without notice - please ensure
you are using the most recent update found at www.APsystems.com
This indicates a situation where failure to follow instructions may cause a serious
hardware failure or personnel injury if not applied appropriately. Use extreme caution
when performing this task.
This indicates information that is important for optimized microinverter operation.
Follow these instructions closely.
1.1 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
website, APsystems.com/Resources.

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 it fails, contact APsystems
Customer Support to obtain an RMA number and start the replacement process. Damaging
or opening the APsystems Microinverter will void the warranty.

CAUTION!
The external protective earthing conductor is connected to the inverter protective earthing
terminal through AC connector. When connecting, connect the AC connector first to ensure
the inverter earthing, then do the DC connections. When disconnecting, disconnect the
AC by opening the branch circuit breaker first, but maintain the protective earthing
conductor in the branch circuit breaker connected to the inverter, then disconnect the DC
inputs.

In any circumstance, do not connect DC input when AC connector is disconnected.
 Please install isolation switching devices on the AC side of the inverter.

CAUTION – Hot surfaces - To reduce the risk of burns - Do not touch. Risk of electric
shock due to, (a) both AC and DC voltage source are terminated inside this equipment,
and (b) when the photovoltaic array is exposed to light, it supplies a DC voltage to this
equipment. Each circuit must be individually disconnected before servicing. Warranty void
if micorinverter cover removed. The microinverter has no serviceable internal parts.
Refer servicing to qualified APsystems service personnel. This inverter has an
integral ground-fault detector/interrupter (GFDI). This Utility-Interactive Inverter
contains active anti-islanding protection (IEEE1547) and is tested per FCC/IC.
