| Turn the DC switch on and off ten consecutive times to make sure that it is working properly.| ****

Once a year

Electrical Connection

| Check whether the cables are securely connected. Check whether the cables are broken or whether there is any exposed copper core.| ****

Once 6-12 months

Sealing

| Check whether all the terminals and ports are properly sealed. Reseal the cable hole if it is not sealed or too big.| ****

Once a year
