Cables - Xantrex Truecharge TC20+ Owner's Manual

Maintaining and Cleaning
Reconnect the battery cable terminals to the battery lugs and tighten to
approximately 10–15 foot-pounds using the torque wrench. If you do not
have a torque wrench, use an appropriate tool to tighten the bolts
reasonably snug. Do not over-tighten.
After tightening the cables, evenly coat all the exposed metal surfaces of
the battery terminals and lugs with liquid neoprene. This will cure to form
an airtight protective layer. If liquid neoprene is not available, use a light
coating of anti-corrosion grease or other sealant. Do not let anything
come between the mating surfaces of the lugs and terminals.

Cables

Inspect all battery cables for missing or damaged insulation or loose
connections. Inspect any openings that the cables pass through. All such
openings must be equipped with a rubber grommet or conduit to prevent
chafing on the cable. If necessary, replace worn grommets. If the cable
insulation is worn, replace the cable.
