Mounting the CDR500 Repeater

To mount the CDR500 repeater to a wall or other
mounting surface, we recommend using the accessory
mounting plate (HLN9169). If you use the accessory
mounting plate to mount the CDR500 repeater, follow
the directions included with it. If you do not use the
mounting plate, refer to Figure 2-7 (not to scale) for the
locations of the wall mounting holes for the CDR500
repeater.
CAUTION
The CDR500 repeater weighs approxi-
mately 50 pounds (22.7 kg) when assem-
bled. Lifting improperly can cause
injury.
Get help from a second person and use
care when lifting the CDR500 repeater.
CAUTION
The CDR500 repeater weighs approxi-
mately 50 pounds (22.7 kg) when fully
assembled, and can fall if not properly
mounted.
Use proper hardware and mount the
CDR500 repeater only to a structurally
sound wall or mounting surface.
March, 2001
If the CDR500 repeater is mounted in an
area of high vibration, incorrect mount-
ing hardware can loosen.
To prevent loosening of the mounting
hardware, use high strength fasteners
and lockwashers to mount the CDR500
repeater.
A dirty or plugged fan grill (on the bot-
tom of the mounted unit) can cause
overheating or improper operation.
Clean dust and debris periodically from
the grill, and allow sufficient air flow to
the fan.
The CDR500 repeater is designed for
indoor use.
Install in a location that is protected from
the weather and outdoor environment.
To operate the CDR500 repeater, the
antenna feed line, ac line cord, ground
cable, (optional) phone lines, and
(optional) battery cables must be con-
nected to the bottom of the unit.
When mounting the CDR500 repeater, plan
for cable access to the bottom of the unit.

Final Assembly

To operate the CDR500 repeater, you must connect all
of the necessary cables and accessories to the bottom of
the CDR500 repeater (refer to Figure 2-4 on page 2-4):
1. Attach a ground wire from an absolute earth
ground to the 1/4" threaded grounding stud
on the far right of the CDR500 repeater, using
one of the lockwashers and nuts provided in
Bag 2.
(20 to 30 in.-lbs.) torque.
2. Connect lightning arrestors.
Lightning can damage the CDR500
repeater and its components if the unit
is not grounded properly.
For lightning protection, ground the
CDR500 repeater to an absolute earth
ground using at least #6 gauge copper
wire, and use adequate lightning arres-
tors.
3. Connect the antenna lead(s) to the antenna
connector(s) on the far left of the CDR500
repeater.
