(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
(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 connections on the junction
box should not be used for single unit
All connectors are hot when used. Do
not remove caps from unused hocks.
c. Cable Connections for two PU 794/Gs.
Two PU 794s are not to be continu-
ously operated in parallel, only to
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
(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-
2-4. Initial Adjustments
Perform the PMCS in Table 2-1 before operating the
