Check for externally visible damage and discoloration of the DC Isolator and the cables at
regular intervals.If there is any visible damage to the DC Isolator, or visible discoloration
or damage to the cables, contact the installer.

Once a year, turn the rotary switch of the DC Isolator from the On position to the Off
position 5 times in succession. This cleans the contacts of the rotary switch and
prolongs the electrical endurance of the DC Isolator.
