Determine the mounting location of the SNM941 device
The SNM941 can be installed in various locations; however the recommended location is in the cab or a 
side compartment, but not the engine compartment, to allow for: 
ease of access
increased  security
a minimal distance from the antennas and control box to the main unit.
SIM card access
The SNM941 mounting plate is designed to be fixed in an area with the dimensions of 185 mm x 230 mm 
(7.28 in x 9.05 in), to allow adequate space for attachment of the electrical harness, as well as the 
coaxial antenna connections. 
C
CAUTION – 
Maximum operating temperature is +85° C and maximum storage temperature is 
+85° C.
Be sure to avoid mounting the unit in an area with excessive exposure to moisture, dirt, direct heat, 
sunlight and chemicals, while still allowing for accessibility, as well as good air flow. 
Plan the route of the electrical harness
Keep in mind the following factors:
The 34-pin connector on the electrical harness must reach and attach to the SNM941 device. It is not 
necessary to plug the connector into the SNM941 at this time. Be sure to disconnect the harness 
before beginning make any other electrical harness connections in steps 3 & 4
.
Ensure that the brown connector on the SNM941 harness can easily reach the corresponding brown 
connector on the GCS/AccuGrade harness. If there is no brown connector on the GCS/AccuGrade 
harness, refer to the 
SNM941 Ordering Guide
 (this can be found online in the Trimble Store help 
files). 
Secure the SNM941 device
Trimble recommends that you use the provided mounting bracket for installation of the SNM941. If 
the chosen mounting location is outside of the cab on a tracked vehicle, then the shock plate must be 
used. Please note that the shock mount must be bolted to the machine. In most cases this means 
that the holes must be drilled to accommodate for this.
 
If the mounting bracket is not to be used, drill a rectangular array of 7 mm (¼") holes with the 
dimensions of 215.4 mm x 60 mm (8.48" x 2.36"). 
Secure the SNM941 to the mounting position using four M6 or ¼" bolts, nuts, and washers. 
Firmly tighten the bolts.
