The RM7800 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 cir cuit.
The RM7800 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 by minimum length conduct ors
having maximum surface areas. Wide straps or brackets are preferred rather than leadwires. Be careful to ensure that mechanical ly
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.
