9.2 Cleaning the Handle Covers

For optimal heat dissipation of the device, the handle covers must be clean. Clean the handle covers

regularly.

1. Remove the handle covers. To do this, put your

finger up into the space between the handle covers

and the enclosure and pull the handle covers to the

side.

2. Clean the handle covers with a soft brush or a paint brush.

3. Re-attach the handle covers to the inverter.

The side on which they are to be mounted is stated

on the inside of the handle covers ("links/left" and

"rechts/right").

9.3 Checking the DC Disconnect

It is recommended, though not compulsory, to:

• Check the DC Disconnect regularly.

• Activate the DC Disconnect 10 times in a row once a year.

Insects can enter the Sunny Boy

Potential damage to the Sunny Boy.

• The handle covers must not be removed permanently, otherwise the inverter is not protected

against the ingress of insects.

In the case of normal use, the DC Disconnect does not require any maintenance.

Operating the switch cleans the contacts and extends the life of the DC Disconnect.
