Power Supply
The system comes with 2m length power cable, fitted with moulded M12 female 4-core cable to
plug into Cab Alert Unit and flying leads at other. The system connects to +12V or +24V DC supply via
2A fuse.
Voltage above 24V requires a Voltage Reducer to lower voltage into range 12-24V DC.
The Cab Alert unit receives power from the vehicle electrical system, Sensor units receive power
from the Cab Alert connector.

Power Supply wiring Examples
The system operates from the vehicle’s 12V or 24V DC power supply. If the vehicle’s supply voltage is
higher than 24V DC, then a voltage reduce is required. When logging is required, “Ignition Sense”
connects to the ignition switch. When logging is not required, “Ignition Sense” connects to 12V DC
input signal.
IMPORTANT: Tag Detection will only occur when the WHITE “Ignition Sense” wire
connects to the supply voltage
.
12/24V DC supply, NO logging
