7. Service and Replacement

PV Powered provides service guidelines for disconnecting and replacing

an inverter. Always request and receive a replacement prior to

separating the inverter from the Integrated AC/DC Disconnect

assembly. PV Powered maintains an advanced replacement policy

which provides qualied personnel with a similar inverter for immediate

replacement of the unit being removed.

In the unlikely event the inverter requires replacement, the disconnect

remains in place. Only the inverter is removed and immediately replaced.

2. Remove the screws located around the front perimeter of the inverter

and remove the lid.
