Connectloose end of the ground wire assembly to the damp.Tighten the damp screw (10). Ensure that all groundwire connections are tight.b. CableConnectionsforasinglePU794/GWhen making cable connections, PU794/6 must be shut down. Failure toobserve this warning could result indeath by electrocution.(1) Remove all the cables from the reel andtray.(2) Connect the 5-foot (1.52 meters) controlcable between the control connector on the connectorplate and the control connection on the junction box forunit 1 (Figure 2-3).(3) Connect the 100-foot (30.46 meters) con-trol cable to the remote connector on the junction box.Connect the other end of the control cable to the con-trol cable connection on the front of the shelter (Fig-ures 2-3 and 2-4).(4) Connect one end of the power cable to thepower connector on the generator (not on the junctionbox), and the other end of the power cable to the con-nector on the shelter.All pins are live on the junction boxpower connectors.Power connections on the junctionbox should not be used for single unitoperation.All connectors are hot when used. Donot remove caps from unused hocks.2-12Change 6(5) Deleted.c.
