Power and Ground Wiring
This is a 28 VDC monitor that requires 1.3 Amp of power to operate. To operate
properly this monitor requires an input voltage of 18-29 VDC.
The rated current of the equipment and associated voltage drop should be taken into
consideration when selecting wire gauge. The following example is based on an
install with a 28 VDC power system and a total of 50 feet of wire between the circuit
breaker, monitor and ground.
Example: 22awg wire has 16.2 Ohms per 1000 feet, this equates to .81 Ohms for 50
feet. 1.3 Amp of current on .81 Ohms will drop 1.06 Volts.

Also, use short heavy gauge wire and a clean tight connection for ground.
It is the installer's responsibility to understand the product's requirements to install the
product in compliance with industry standards and safety.
