The RM7885A must have an earth ground providing a connection between the subbase and the control panel or the
equipment. The earth ground wire must be capable of conducting the current to blow the 20A fuse (or breaker) in event
of an internal short circuit. The RM7885A needs a low impedance ground connection to the equipment frame that, in turn,
needs a low impedance connection to earth ground. For a ground path to be low impedance at RF frequencies, the
connection must be made with minimum length conductors having maximum surface areas. Wide straps or brackets
rather than leadwires are preferred. Be careful to verify that mechanically tightened joints along the ground path, such
as pipe or conduit threads or surfaces held together with fasteners, are free of nonconductive coatings and are protected
against mating surface corrosion.
