WARNING:
Be aware that only qualified personnel should troubleshoot the
APS micro-inverter.
WARNING:
Never disconnect the DC wire connectors under load. Ensure that
no current is flowing in the DC wires prior to disconnecting. An opaque
covering may be used to cover the module prior to disconnecting the module.
WARNING:
Always disconnect AC power before disconnecting the PV module
wires from the APS micro-inverter. The AC connector of the first micro-inverter
in a branch circuit is suitable as a disconnecting means once the AC branch
circuit breaker in the load center has been opened.
WARNING:
The APS micro-inverter is powered by PV module DC power.
Make sure you disconnect and reconnect the DC connections to watch for the
three short LED flashes.
