The R7140 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 15A fast blow fuse (or breaker) in the event of an internal short
circuit. The R7140 needs a low impedance ground connection to the equipment frame, which, in turn, needs a low impedance
connection to earth ground.
