Model 1010 Radio/Gps Unit Installation - OPTICOM 764 Installation Manual

3.1.1 Model 1010 Radio/GPS Unit Installation

NOTE:
The mounting location must provide a 3/4-inch NPT internal thread mount. Mounting brackets, nipples,
pipe and lock nuts are not included.
Choose the mounting location. This is usually the mast arm or span wire pole nearest the traffic controller
cabinet. The cable run from the radio/GPS unit to the phase selector (located in the traffic controller
cabinet) should not exceed 250 feet (76 m).
Screw a nipple (or pipe) into the base of the radio/GPS unit. Do not tighten the locknuts yet.
Loosen the two cover screws and remove the wiring cover.
Route the radio/GPS cable from the radio mounting location to the traffic controller cabinet. The cable can
enter the radio/GPS unit either through the cable retainer in the wiring cover or through the nipple/pipe at
the base of the unit. See Figure 3-5. In either case, the wiring connections are the same.
For purposes of discussion, these instructions assume the cable enters the radio/GPS unit through the cable
retainer.
