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:

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

Ensure that you are prepared with various installation tools as each installation can be unique to the
machine that it is installed on.
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.
