The RM7895 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 RM7895 needs a low impedance ground connection to the equipment frame which, 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 that have 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.
