Note: Refer to FIgure 2 for Steps 2 through 5.
STEP 2— Locate the flat head screws, Item 4, supplied with the kit and attach the Base Plate, Item 2,
to the rear of the cabinet using three of the screws supplied (the remaining screws are
spares). Make sure that the countersunk holes of the plate are facing outward and the
gasket is facing towards the rear of the cabinet. The two carriage bolts on the rear of the
power cabinet should protrude through the clearance holes in the plate.
STEP 3— Place the Spacer Panel, Item 3, on the base plate via the four studs attached to the base
plate. Check the orientation of the spacer panel and make sure that the holes closest to the
edge of the panel are at the top when installed.
STEP 4— Open the AC Generator Receptacle Assembly, using the tool (Item 8) provided with the kit
and remove the inner circuit breaker and AC inlet covers to access the rear of the box.
STEP 5— Place the AC Generator Receptacle Assembly on the studs located on the Base Plate
previously installed. Attach the box securely to the Base Plate using the four 1/4-20
SEELNUTS, Item 5, provided.
Note: The rubber side of the SEELNUT should be facing toward the panel.

STEP 9— Loosen compression fitting nut located on the end of the shorter piece of conduit and
remove the fitting portion keeping the sealing ring in place and ensure the nut and
compression ring remain on the conduit (Figure 5).
STEP 10— Swing the Power Cabinet AC pull box up 90˚ into the horizontal position as shown in Figure
5 and attach the fitting removed in Step 9 to the end of the Power Cabinet AC pull box.
Ensure the sealing ring is in place between the fitting and the AC pull box.
STEP 11— Push the shorter conduit through the fitting installed to the AC pull box in Step 10. Loosen
the fitting in the bottom of the AC Generator Receptacle Assembly and adjust the conduit
assembly to its proper position. Now tighten both compression fittings using a tool to
secure the conduits.
STEP 12— Apply RTV silicone around all fitting/conduit interfaces to provide continuous seals (Figure
3).
STEP 13— Open the front door of the Power Cabinet with the tool provided and locate the AC Power
Panel in the lower right corner of the cabinet (Figure 6). Remove the four cover screws to
access the wiring and circuit breakers (Figure 7).
STEP 14— Remove both AC pull box covers and gaskets (Figure 5). Locate the AC wires coiled up
inside the AC Generator Receptacle Assembly. There should be three No. 2 AWG wires
(white, red, black) and one No. 6 wire (green). Feed the AC wires through the bottom of the
assembly one at a time and out through the AC pull box located on the conduit assembly
(Figure 5). Feed the AC wires through the shorter conduit, one at a time, and into the Power
Cabinet. Route these wires to the front of the Power Cabinet over to the AC Power Panel
located in the bottom front of the Power Cabinet (Figures 6 and 7).
STEP 15— Refer to the AC Generator Receptacle schematic (Figure 4) and the AC Power Panel
schematic (Figure 8) and connect the wires as shown. The red and black “hot” wires from
the terminal block above CB1A, of the AC Generator Receptacle, should be connected to
CB1 of the AC Power Panel. The white “neutral” wire should be connected to the neutral
bus, and the green No. 6 ground wire should be connected to position No. 20 of the AC
Power Panel ground bus (Figure 8).
STEP 16— Replace both of the AC Pull Box covers and gaskets and secure with the screws removed
in Step 14 (refer to Figure 5).
STEP 17— Route the No. 6 AWG solid ground wire from the grounding electrode (not provided)
through the black plastic fitting in the bottom of the AC Generator Receptacle Assembly to
the second position on the left ground bus. Connect securely to the ground bus and
tighten the black plastic fitting around the ground wire to ensure proper sealing (refer to
Figure 9 and schematic in Figure 4).

STEP 20— Connect the AC utility wiring to the neutral bus and Circuit breaker CB1A as shown in
Figures 4 and 9.
Note: If this Inlet is being installed as “Service Entrance Equipment”, proceed to Step 21. If not “Service
Entrance Equipment”, skip to Step 22.
STEP 21— For “Service Entrance Equipment”, locate the Green Bond Strap connected to the ground
bus and tagged as “BOND STRAP” located in the AC Generator Receptacle Assembly.
Connect this to the neutral bus as shown in Figure 4 and proceed to Step 23.
STEP 22— If this is not being installed as “Service Entrance Equipment”, a No. 6 AWG ground wire is
required from the AC utility service and should be connected to the ground bus as shown
in Figure 4. Remove the Green Bond Strap connected to the ground bus and tagged as
“BONDSTRAP” and discard. Proceed to Step 23.
STEP 23— Remove and discard the Bond Strap located in the AC Power Panel located in the Power
Cabinet (Figure 8).
Note: Check all wiring to ensure unit is wired correctly before proceeding.
STEP 24— Replace the AC Power Panel Cover with the screws removed in Step 13 (Figure 7).
STEP 25— Replace the inner circuit breaker and AC inlet covers, removed in Step 4, with the hardware
provided (refer to Figure 2).
Note: If the system is to be powered-up at this time, ensure that the Interlock Mechanism is secured in
the lowest position, CB1A is in the ON position, CB2A is in the OFF position (Figure 10), and CB1
of the AC Power Panel is in the ON Position (Figure 7).

SECTION B
AC Wiring to an Existing and Operating System:
Warning: The safest condition for working on this equipment is with the equipment in the de-energized
state. If the equipment is to be installed to an operating system, the owner/operator of the
system must be consulted. The owner/operator must provide approval whether the system
shall be de-energized, or the work is to be performed while the system is energized. The
procedures in this manual cover installation of the equipment. It does not include safety
procedures. When this manual is used to install equipment to energized circuits or equipment,
the appropriate safety procedures must be followed.
Some things to be advised of are:
• Only qualified personnel should install and service this equipment. Personnel must be properly trained
and follow appropriate safety practices and procedures.
• Hazardous energy and voltages may be present in the equipment and on interface cables, and can
cause serious injury or death if safety precautions are ignored.
• Due to the possibility of contacting energized circuits during these installation procedures, all tools and
equipment must be insulated in an approved manner.
All safety practices of your company and any governing bodies (for example, OSHA) should be followed.
Notice: Since every Cell Site location is unique, careful evaluation of the site must be performed to determine
the safest and most practical method to install the AC Generator Receptacle to the 60C Power Cabinet at an
operating Cell Site.
Some things to be evaluated are:
• Safety of installation personnel.
• The effect on the customer if the Cell is taken out-of-service.
• Risk of damage to the equipment from accidental short circuits.
• Job planning to reduce the required AC service downtime.
• Assessed need for temporary additional DC power.
This is a partial list of considerations to be made. Ultimately, the owner/operator of Cell Site must be consulted
and decide how the equipment will be installed.

Note: Perform Steps 1 through 6 in Section A before performing the following steps.
STEP 1— Turn off the external AC service to the Power Cabinet. The system will now operate on
batteries for the Initial Battery Reserve time listed in the table below.
STEP 2— Open the front door of the Power Cabinet with the tool provided in the kit and turn off the
main breaker, CB1, located in the AC Power Panel at the bottom of the Power Cabinet (refer
to Figures 6 and 7).
STEP 3— Open the front cover of the AC Power Panel by removing the four cover screws to access
the wiring and circuit breakers (Figure 7).
STEP 4— Disconnect the existing AC Service Wiring and Conduit. Also, disconnect the ground
electrode conductor (refer to Figures 1 and 8).
STEP 5— Proceed to Section A, and perform Steps 7 through 26.
* End-of-Life Battery Reserve is estimated at 80 percent of Initial Battery Reserve.
