2.
Open LH compartment access door to the fridge battery
3.
Turn OFF the main switch on the side or front of the Carrier Controller cabinet

First Step
– Install Antenna’s:
GSM and GPS Antennas:
1.
Locate the GSM and GPS Antennas on top of the carrier system painter steel frame as pictured below.
The base of each antenna is magnetic and they can be attached directly to the steel frame. Run a bead
of Sigaflex or a similar adhesive product around the base of the antenna to ensure that it
won’t
come
free with vibration.
2.
Locate the antennas as pictured to ensure maximum separation between the two devices to deliver
optimal performance.
3.
From the top side insert the antenna cables in split tubing and feed through the hole in the fridge
frame
4.
Retrieve the cables from the hole lower down the frame just above the battery compartment close to
where the UMD Gateway unit will be installed.
5.
Cable tie the co-
axial cables to the Carrier system’s wiring harness or
fixed hardware that does not get
hot.
6.
Loop and secure the excess co-axial cable in the reefer cavity and connect and finger tighten the co-
axial connectors to the UMD.
