1.2 POWER CONNECTION
This connection is the main power connection for the system. The system can operate from 10V to 30V (12V to
24V nominal).
•
10V-30V, GROUND - POWER SUPPLY:
These are the power supply 2 connections to the system. Power should be connected to the ignition
side of the key (so power does not disconnect during engine cranking). To prevent flat batteries, the
system should be powered after any isolator switches so the system loses power when the isolator is
turned off. The system is internally over-current protected but external fuse protection is also
recommended for additional safety:
o
Recommended external fuse protection: 3 Amp
o
Maximum current (operational – ON via control panel): 1 Amp
o
Maximum current (shutdown – OFF via control panel): 100mA
•
PCON1, PCON2 - REMOTE POWER CONTROL:
If a control panel is not used with the system, shorting these two connections together via a switch
offer an alternative method of powering up the system remotely.
