EMR4 Truck Installation
Input Power – Critical Ground Connection
Installations With High Amperage Devices
The input power for an EMR4 must be isolated from devices that use large amounts of electric current such as reel
motors. Connect the EMR4 using dedicated wiring between the voltage source and the Interconnect Box. On
vehicles with multiple voltage sources it may be necessary to use a separate battery or voltage source to power
the EMR4. Also, a battery isolator can be used between the voltage source and the IB to prevent voltage spikes
from entering the Interconnect Box when the high amperage devices are de-energized.
Recharging Vehicle Batteries
In the Interconnect Box, disconnect the wires for both the INPUT-PWR and GND Terminals while charging the
vehicle’s battery. Failure to do so can result in hardware damage to the circuit board inside the Interconnect Box.
