Terminal covers Color-coded snap-on DC terminal covers are provided to prevent accidental contact with
the terminals. Terminal covers are required for all installations, even if a XW Conduit Box
is used. It is also recommended that the shank of the ring terminals (cable lugs) be covered
with heat shrink or some other form of insulation.
