Intersection Equipment Installation Instructions

5.3.2.1 Radio/GPS Unit Cable Terminations

1. Route the cables from the radio/GPS
antenna through the cabinet to the
radio/GPS unit location.
2. Coil up any excess cable.
NOTE: When coiling excess cable do not create
any sharp bends in the cable or the cable may be
damaged.
3. Connect the cable labeled GPS to the GPS
connector on the radio/GPS unit. Connect
the other cable to the Radio connector.
Tighten the connectors using a 5/16 inch
wrench (an 8 mm wrench may also be
used).
4. Plug the 15 pin connector of the
radio/GPS cable (black cable) into the P1
connector of the radio/GPS unit and
tighten the screws.
5. Route the cable to the location where the
phase selector will be installed.
6. Skip to Section 5.5.2 for details on
connecting the radio/GPS cable.
NOTE:
1. The connectors are keyed and
cannot be connected to the wrong
connector.
2. To avoid damage to the equipment
always connect the GPS and Radio
connectors before connecting the
radio/GPS cable. Plug the cable into
the phase selector last.
3. The radio/GPS unit is not watertight;
therefore it should be mounted inside
the cabinet compartment.
4. Never operate the equipment with the
antenna cables disconnected or the
equipment may be damaged.
