Appendix F: SIR 30 Wiring Instructions
The SIR30 runs with a DC input from +10VDC to +28VDC. It will not turn on unless there is a minimum
of +10V at the power connector. The system will shut down immediately if the input drops below +9V
under load. The input DC current requirement is a function of the number of antennas and the input
voltage. For reliable operation, the wiring should support 300W to the unit, although typical power
consumption will be much less. This is 30A at the minimum voltage.
The AC Supply provided with the unit pr24V when connected to a wide range of mains voltages.
The DC input connector has 5 pins assigned as follows:
•
PIN A = INPUT +
•
PIN B = INPUT +
•
PIN C = INPUT – (GND)
•
PIN D = INPUT – (GND)
•
PIN E = IGNITION
In order for the SIR30 to turn ON the INPUT pins should all be wired as indicated and the IGNITION pin
needs to be connected to a voltage in the range of +5V to +INPUT.
Wiring Options
AC Power:
In this mode, the AC power supply is connected to the SIR30 Power connector. Mains
voltage should be supplied to the AC supply at all times while the unit is in use. The Power Switch on the
SIR30 Front Panel should be used to turn the system on and off.
Do not interrupt power to the AC supply while the system is in operation.
DC Battery Cable:
no ignition wiring.
The DC Battery Cable has two clips that can be used to power the system. Be sure to connect the RED
clamp to the POSITIVE (+) terminal of the battery. The BLACK clamp connects to the NEGATIVE (-)
terminal of the battery. The Power Switch on the SIR30 Front Panel should be used to turn the system on
and off.
The power connector back shell has a short wire loop connecting a green wire plug (P1) with a red wire
jack (J2). Leave this loop connected. Do not remove either clamp while the system is in operation.
DC Battery Cable:
direct wiring with ignition connection.
The DC Battery Cable has two nuts that attach the battery clips to the cable. If these nuts are removed, the
cable can be attached directly to the battery lugs or a terminal block that is supplied with power all of the
time the unit is in use.
With this wiring option it is recommended that the IGNITION terminal be connected. This will prevent
the unit from draining the vehicle battery if inadvertently left on. If the SIR30 Power Switch is left in the
ON position, the SIR30 will turn on and off with the vehicle ignition.
To connect the ignition line, disconnect J2 and P1. Connect the P1 (green wire) to a DC source that turns
on and off with the vehicle. Leave J2 disconnected.
