Cable Connections for a single PU 794/G

TM 5-6115-634-14&P NAVFAC P-8-647-14&P TO-35C2-3-445-14 (i) Connect a damp (9) to top of the ground rod and reconnect the ground rod coupler (5). Connect loose end of the ground wire assembly to the damp. Tighten the damp screw (10). Ensure that all ground wire connections are tight. b. Cable Connections for a single PU 794/G When making cable connections, PU 794/6 must be shut down. Failure to observe this warning could result in death by electrocution. (1) Remove all the cables from the reel and tray. (2) Connect the 5-foot (1.52 meters) control cable between the control connector on the connector plate and the control connection on the junction box for unit 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 the power connector on the generator (not on the junction box), and the other end of the power cable to the con- nector on the shelter. All pins are live on the junction box power connectors. Power connections on the junction box should not be used for single unit operation. All connectors are hot when used. Do not remove caps from unused hocks. 2-12 Change 6 (5) Deleted. c. Cable Connections for two PU 794/Gs. NOTE Two PU 794’s are not to be continu- ously operated in parallel, only to transfer power. When making cable connections, both PU 794/Gs must be shut down due to feedback from and operating unit. Failure to observe this warning could result in death by electrocution. (1) Connect the first PU 794/G following para- graph b. above. Designate this unit as unit number 1. All connections to the junction box will be made at this unit. (2) Connect the grounding wire of the second PU 794/G to the ground rod of the first PU 794/G. (3) Connect the 25-foot (7.62 meters) control cable from the control connector on the connector plate of unit 2 to the unit 2 control connection of the junction box on unit 1 (Figure 2-5). (4) Connect the 25-foot (7.62 meters) power cable between the power connector on the connector plate of unit 2 and the unit 2 power connection of the junction box on unit 1 (Figure 2-5) (5) Connect the 25-foot (7.62 meters) parallel cable to the parallel connectors on both unit 1 and unit 2 (Figures 2-3 and 2-5). (6) At both generator sets place the PARALLEL OPERATION/SINGLE UNIT OPERATION switch on the generator control panel to the PARALLEL OPERA- TION position. 2-4. Initial Adjustments Perform the PMCS in Table 2-1 before operating the PU 794/G.
