APPENDIX D — TRANSCEIVER CABLES
D.1 TRANSCEIVER POWER CABLES
Warning – Applying an incorrect voltage to a transceiver can cause damage. Confirm the voltage rating of
the transceiver and power source before applying power.
Caution – Power should never be applied to any system unless the user is acutely aware of his intentions and
the environment in which the unit is operating. Applying power to an improperly-terminated radio
transceiver could result in damage to the radio transceiver, cause operator injury, or violate regulatory laws
regarding radio transceiver transmissions as radios will begin transmitting full-rated power without any user
intervention under certain conditions.
Important! Transceivers do not have a power switch. Applying power to the power port powers on the transceiver.
Verify that the power is off before connecting the unit to a power source.
D.1.1 BASE STATION TRANSCEIVER POWER CABLE

power connectors are threaded posts for ring lug terminals and are located on the rear panel of the unit.
The following figure shows recommended construction of a power cable and the lock washers and nuts required to
