The AG52 and AG53 are compatible with most Thermo King models. To confirm compatibility, see the Compatibility Reference Guide. For all installation types, you will need the CBL-AG-BRTK cable (Install Guide).

Use the following instructions to complete the installation:

Note

This hardware integration may incur additional costs from Thermo King. Contact your Thermo King representative for more details.

Install AG52/AG53 on Reefer with Thermo King iBox

To install your AG52 or AG53 on a Thermo King reefer with an iBox, use the following workflow:

  1. Activate the device in the Samsara dashboard if you have not already done so.

    Log into the Samsara dashboard or go to https://cloud.samsara.com/activate. You can also follow the link in your Order Shipped email.

  2. Turn off the reefer master power.

  3. For models prior to 2017 without a BlueBox, connect the REB iBox to the J98 10-pin connector on the control board.

  4. Connect the iBox harness to the iBox.

  5. Open the Thermo King electronics control box (unbolt if necessary). Route the reefer end of the cable into the control box through the rear grommet and then connect the cable to the iBox harness using the 6 pin deutsch connector.

  6. Select the desired mounting location. Avoid locations with extreme temperatures that could damage the device or cable.

    Typical locations are on the ceiling of the reefer (avoiding the cooling fan) or on the outside of the trailer.

    Tip

    When selecting a location for your device, reference the following tips:

    • Verify that the cable has adequate clearance to reach the AG and the electrical connection.

    • For the most reliable connectivity, ensure that the AG has at least one unobstructed side, facing the sky or ground, for example.

    • Avoid installing the device within metallic structures, such as within metal trailers. Placement in such structures may adversely impact device cellular and GPS connectivity.

  7. Attach the mounting bracket to the mounting surface using one of the following methods:

    Caution

    To prevent damage to the mounting tabs, tighten screws to a maximum torque of 1.4 Nm (12.4 lbf-in). If using your own screws, ensure they are not larger than the size specified below.

    • Self-drilling screws: Use the provided #6 self-drilling screws.

    • Machine screws: Drill through-holes for the mounting bracket and secure it using the provided 6-32 machine screws, washers, and lock nuts.

  8. Plug the cable into the AG and twist to lock.

  9. Mount the AG to the bracket using the instructions in the following table. Instructions vary based on your installation scenario (standard or hazardous location).

    Caution

    To prevent damage to the mounting tabs, tighten screws to a maximum torque of 1.4 Nm (12.4 lbf-in). If using your own screws, ensure they are not larger than the size specified below.

    Hazardous Location Mounting Instructions

    Mount the AG directly to the bracket.

  10. Reference AG LED Statuses and Actions and perform the action that corresponds to the observed LED behavior.

  11. Work with your local Thermo King dealer to configure the reefer HMI for third-party access and remote control in the guarded access menu.

  12. To confirm installation, turn the reefer on and wait 2 minutes. Then from your Samsara dashboard, turn the reefer off from your dashboard (for more information, see Reefer Integration).

Install AG52/AG53 on Reefer with Thermo King Bluebox

Before Samsara can communicate with your reefer unit, you will need your BlueBox remotely configured to iBox mode. To do this, work with your local Thermo King dealer or provide the Thermo King support team with your BlueBox serial number (SN) and IMEI at tracking@thermoking.com.

To install your AG52 or AG53 on a Thermo King reefer with a BlueBox, use the following workflow:

  1. Activate the device in the Samsara dashboard if you have not already done so.

    Log into the Samsara dashboard or go to https://cloud.samsara.com/activate. You can also follow the link in your Order Shipped email.
