Assembling the CDR700 Repeater Housing

Mounting the Module in the CDR700 Housing

1. If necessary, unplug the ac line cord of the
HPN9033 power supply unit from the ac
mains.
2. If necessary, unplug the dc power cable from
the HPN9033 power supply unit to the Y-split
power cable.
3. If necessary, unplug the fan power cable to the
fan.
4. The module mounts near the top center of the
back wall of the inside, above the fan assem-
bly of the CDR700 chassis. Observe the hole
pattern shown in Figure 3-7.

5. Locate the Battery Revert module in the
HLN9455 Battery Revert kit.
6. Locate two (2) of the M3.0 x 0.5 x 10 mm black,
panhead, machine screws supplied in kit
HLN9455.
7. Position the module with the plastic cover
down and the cables exiting to the right.
8. Start the two (2) M3.0 screws into the upper
lefthand and lower righthand corner threaded
holes in the bottom of the chassis of the mod-
ule. Two to three turns are sufficient.
9. Place the Battery Revert module into the
inside of the CDR700 housing. Ensure that the
cables of the module extend downward
(toward the fan). The heads of the two (2)
screws threaded into the module in Step 8
pass through the keyholes in the CDR700
chassis back panel.

The two cables from the left side of the
battery revert module pass to the left side
of the fan assembly. The three cables from
the right side of the module pass to the
right side of the assembly.
10. Slide the module to the left until it is snug
against the narrow slots of the keyholes.
11. Locate the remaining two (2) of the M3.0 x 0.5
x 10 mm black, panhead, machine screws sup-
plied in the HLN9455 Battery Revert kit.
12. Pass the screws through the two empty
mounting holes in the CDR700 chassis back
panel. Turn the screws into the threaded holes
of the chassis of the Battery Revert module.
13. Secure the module to the CDR700 housing by
tightening all four (4) M3.0 screws to 0.68-0.90
N-m (6-8 in-lbs).
Installing the Internal Equipment Bracket
Module
1. Place the assembled internal equipment
bracket module on the chassis of the CDR700
repeater housing.
2. Tilt the bracket slightly upward at the right
side and slide the left side notched mounting
tabs on the module under the TT4.0 screws.
3. Replace the two (2) TT4.0 screws removed
from the right side in Step 2 under "Removing
the Internal Equipment Bracket" on page 3-3.
Tighten all four (4) TT4.0 screws to 1.58 N-m
(14 in.-lbs.) torque.
4. Tighten all six (6) M5 x 0.8 x 8, T25 Torx, pan
head, machine screws that secure the receive
and transmit radios and the repeater control-
ler to the bracket to 3.16 N-m (28 in.-lbs.)
torque. If you loosened the screws that secure
the power supply to the bracket, tighten them
to 3.16 N-m (28 in.-lbs.) torque.
5. If the HLN9455 Battery Revert Module has
been installed, skip to "Connecting the Battery
Revert Cables".
6. If the HLN9455 Battery Revert Module has
not been installed, connect the 6-position fan
cable connector to the fan supply connector of
the pigtail from the power supply. Skip to
"Attaching the External Duplexer RF Cables"
or "Attaching the Internal Duplexer RF
Cables".
