Mount and ground chassis

If you intend to install the TX40 in a vehicle, follow these directions for mounting and grounding the device.

Note Always follow the vehicle manufacturer recommendations for electrical accessories connections.

Step 1: Mount the device following these general guidelines:

Device position allows easy access to all ports located on the back of the device.
Device position allows you to easily view the LEDs located on the front of the device.
Device location is away from direct exposure to the elements, such as sun, rain, dust, and similar conditions.
Device and cables should not be near high amperage or exposed to extreme temperatures.
Device and cables should be installed in an area with adequate airflow.

The TX40 has two mounting brackets located on the left and right sides of the device.

For DC installations (with a fixed system ground reference), ground the TX40 chassis to the system ground reference.

For proper grounding reference:

Attach the device to a grounded metal surface.
Connect one end of a short AWG or larger gauge wire to the upper-right grounding and connect the other end to the vehicle chassis.
The TX40 can be grounded through the –VE connection on the power connector. See TX40 power connector.

Separate Ethernet and power cables from other wiring in the vehicle and route the cables away from sharp edges.
Use cable strain relief for installations in high-vibration environments.
