Otherwise, electrical shock may occur. q Place a dedicated ground more than 7' (2 m) away from other grounds and do not have it shared with other electric appliances. Fig. 23 Grounding line CAUTION q Be sure to connect the power supply line to the outdoor unit as shown in the wiring diagram. The indoor unit draws its power from the outdoor unit. q Do not run wiring for antenna, signal, or power lines of television, radio, stereo, telephone, security system, or intercom any closer than 3'4" (1 m) from the power cable and wires between the indoor and outdoor units.
