Cleaning The Handle Covers; Checking The Dc Disconnect - SMA SUNNY BOY 8000TL-US Installation Manual

SMA America, LLC
9.1.2 Cleaning the handle covers
The Sunny Boy sucks air in from underneath via the fans and blows it out again at the top on both
sides via the handle covers. Clean the handle covers, if they are dirty. Proceed as follows:
1. Remove the handle covers.
Insert your finger above in the space between the
handle cover and the housing and remove the
handle covers to the side.
2. Clean the handle covers with a soft brush, a paint brush, or compressed air.
3. Fasten the handle covers back onto the Sunny Boy.
The handle covers must be attached according to the inside inscription ("links/left" and
"rechts/right").
NOTICE
Insects entering the Sunny Boy can damage the inverter.
• The handle covers must not be removed permanently. Otherwise the device is not
protected against the entrance of insects.
9.2 Checking the DC Disconnect
Under normal use the DC Disconnect does not need maintenance.
It is recommended, though not compulsory to:
• Check the DC Disconnect regularly.
• Operate the DC Disconnect once a year 10 times.
Operating the switch will clean the contacts and will extend the life of the DC Disconnect.
