1 Purpose

This guide provides step-by-step instructions for properly installing and commissioning the GS-495 device to ensure reliable operation, accurate reporting, and long-term durability.


2 Pre-Installation Inspection

  1. Remove the GS-495 from its packaging.

  2. Inspect the device casing and solar panel for any cracks, breaks, or visible damage.

    • Important: If the casing or solar panel is damaged, the device no longer meets its IP67 rating and must not be installed.

  3. Confirm the 3-wire harness is present and free of damage.

  4. Verify the over-the-top mounting bracket is included.


3 Mounting Location Selection

  1. Identify a mounting location on the equipment or trailer that:

    • Provides a clear and unobstructed view of the sky to ensure proper solar charging.

    • Is not shaded by guards, panels, or moving components.

    • Is protected from impact, excessive vibration, and areas where the device could be struck or knocked loose.

  2. Ensure the selected location allows safe routing and securing of the 3-wire harness.

  3. Verify the mounting location does not interfere with normal equipment operation or maintenance.


4 Device Mounting Options

The GS-495 includes an over-the-top mounting bracket. Once the mounting location is verified, secure the device using one of the approved methods below.

Option A — Bolt Mounting

  1. Position the mounting bracket at the selected location.

  2. Drill mounting holes into the equipment to match the bracket.

  3. Attach the GS-495 to the mounted bracket.

  4. Secure the bracket using bolts

    • Tighten hardware until the device is firmly secured.

    • Do not overtighten. Excessive force may crack the casing.

    • Warning: Any casing damage voids the device’s IP67 rating.


Option B — Self-Tapping Screws

  1. Position the mounting bracket at the selected location.

  2. Attach the GS-495 to the mounted bracket.

  3. Secure the bracket using self-tapping screws without drilling completely through the equipment

  4. Confirm the device is securely mounted and does not move.


5 Power Connections (Optional)

  1. Route the included 3-wire harness along the equipment or trailer, securing it to prevent:

    • Chafing

    • Pinching

    • Contact with sharp edges, moving parts, or high-heat areas

  2. The 3-wire harness may be connected to the trailer brake light as a power source.

  3. Make the following electrical connections:

    • Red Wire and Yellow Wire:
      Connect both wires together to the constant power side of the trailer brake light.

    • Black Wire:
      Connect to the ground side of the trailer brake light or a verified chassis ground.

  4. Ensure all electrical connections are:

    • Secure

    • Properly insulated

    • Protected from moisture and vibration

  5. Verify the solar panel has a clear, unobstructed view of the sky and is not shaded.


Wiring Notes & Best Practices

  • Confirm constant power is present at the brake light circuit before finalizing connections.

  • Use approved connectors and weather-resistant insulation.

  • Improper wiring may result in intermittent power or reporting issues.


6 Device Coupling

  1. Once the device is securely mounted and powered, couple the GS-495 to the corresponding piece of equipment using the appropriate platform or system.

  2. If required, configure the device to operate as a CLA device.

  3. Verify the device is correctly associated with the intended asset.


7 Operation & Reporting

  • The GS-495 reports twice daily.

  • Power is maintained through a combination of solar charging and the 3-wire harness, providing reliable operation under normal conditions.
