When the DC cables are connected to the charger, the rubber grommets can be slid towards
the charger's front panel until the screw connections are completely covered.
Please see the image below for further wiring details.
Double check for correct polarity, before connecting the battery cables to the battery!
Wrong polarity will blow an internal fuse and the charger must be returned for service.
Always keep positive and negative cables close to each other to minimize electromagnetic
fields.
