General installation approach
In general, the installation is a simple process, however, failure to follow correct installation guidelines 
will result in a non-functional or dysfunctional unit. Before starting the installation process, consider the 
following guidelines:
Installation length of components and length of connection wires to main unit. Keep in mind that it is 
easier to extend the length of wires 
from
 asset terminals rather than change the location of the 
antennas or control box. 
Ensure that you are prepared with various installation tools as each installation can be unique to the 
machine that it is installed on. 
The installation can be performed by doing the following tasks:
1. Determine the mounting location for the SNM941 device.
2. Determine the mounting location for the 4-In-1 antenna. The length of the cabling on the antenna to 
the SNM941 is 0.6 m. Antenna extension cable is available.
3. Plan the route of the electrical harness.
4. Secure the SNM941 device.
5. Install the fuses – telematics installation only.
6. Make the electrical connections – telematics installation only.
7. Complete the device connections.
Further installation notes
The SNM941 is designed for use on construction equipment. Attaching to the vehicle chassis or 
body is standard procedure and will work well. If possible, avoid attaching the device to a 
subcomponent that is prone to extreme shock or vibration, such as the engine block, or suspension 
components. On a tracked machine, isolation mounts (P/N 84264-20 for telematics and 
Accugrade/GCS installations, and P/N 109530 for Earthworks installations) may be required if 
mounting directly to the chassis.
Ensure that the chosen mounting location of the SNM941 is in a practical location. If installing for a 
specific customer, confirm with the customer that the chosen location is acceptable. For example, 
installation in the lunch box compartment may not be an acceptable location. 
Electrical Interference – The SNM941 device operates well in electrically noisy environments, but 
installation best practices include avoiding close proximity to alternators, generators, electric 
motors, DC to AC converters, switching power supplies, and arc welding equipment. If electrical 
interference is suspected, enclose the SNM941 device wiring harness in a grounded shield wrap or 
grounded conduit.
