Powering through DC Power Injector
Introduction
DC power cable coming from the DC power injector
(1)
must be connected to
a DC Distribution Board.
A circuit breaker
(2)
must be employed between the blue wire of DC power
cable and the negative pole (-) V pole of the Local DC Power Source.
The positive pole (+) V of the Local DC Power Source, which the brown wire
of DC power cable is terminated on, is grounded.
Circuit breaker must remain to the OFF position until the
power at the input of radio (V
in
) to be checked.
V
in
must be measured in the range of -60 V to -40 V.
Procedure
To power up radio unit using the DC power injector, please follow the steps
below:
Step Action
1
Ensure that circuit breaker is in OFF position and connect a
voltmeter to DC Distribution Board to measure the voltages at the
input (IN) of circuit breaker (see schematic above).
The measurement value must be in the range of: -60 ≤ V
in
≤ -40.
2
If measurement value is ok, disconnect the voltmeter and switch
ON the circuit breaker.
3 Wait (approx. 120 sec) for the radio unit to power up.
