6 Cleaning and Care
6.1 Checking the Inverter
• Ask the installer to check for correct inverter operation at regular intervals.
• Check whether the inverter has any visible external damage.
If the inverter has visible external damage, contact the installer.
6.2 Checking the DC Disconnect
• Check for visible external damage and discoloration of the DC Disconnect and the cables at
regular intervals.
If the DC Disconnect has any visible external damage or the cables have externally visible
discoloration or damage, contact the installer.
• Once a year, turn the rotary switch of the
DC Disconnect from the
On
position to the
Off
position 10 times in succession. This cleans the
contacts of the rotary switch and prolongs the
electrical endurance of the DC Disconnect.
