    Installation The trailer MUST be supported per manufacturer's specifications before working underneath. Failure to do so may result in death of serious injury Installing the Power Tongue Jack Remove the foot pad from the Power Tongue Jack, if necessary. Remove the hairpin cotter pin (Fig. 2D) and clevis pin (Fig. 2B) holding the foot pad (Fig. 2C) to the jack leg (Fig.
  • Page 6 Align the 3 holes of the Power Tongue Jack mounting plate (Fig. 4A) with the 3 holes in the coupler (Fig. 4B). Secure the Power Tongue Jack to the coupler plate with three 3/8" - 16 x 1" serrated flange Grade 5 Zinc coated bolts (Fig.

  • Page 7: Installing The Stabilizer

    Installing the Stabilizer NOTE: Do not weld the stabilizer to the trailer. Welding the stabilizer to the trailer voids all warranty claims. Determine the mounting location of the stabilizer. It can be mounted anywhere on the frame in front of the axles as long it remains within the approach angle (Fig. 1). For best system performance, it is recommended the stabilizer be placed as close as possible to the center point between the tongue jack and the axles (Fig.

  • Page 8: Installing The Rear Jacks

    Repeat steps 1-3 for the other side of the frame with the other rear jack. NOTE: Lippert recommends zip-tying the harnesses tight against the rear jack motors to prevent damage to the wire harnesses.

  • Page 9: Installing The Remote Leveling Sensor

    Installing the Remote Leveling Sensor Determine the mounting location of the remote leveling sensor. The sensor has a limited mounting area for proper performance, and must be installed on a cross- member of the frame. It must be in line with or behind the rear leveling jacks (Fig. 11) and be centered in line with the center of the frame as signified by the dotted blue line in (Fig.11).
  • Page 10 Orient the sensor (Fig. 12) so that the arrows are on the top side of it and are pointing the correct directions in relation to the frame (Fig. 13). Fig. 13 Fig. 12 NOTE: Leveling sensor mounting plate may come be pre-installed. If so skip to step 6. Dry fit the mounting plate (Fig.
  • Page 11 Attach the sensor (Fig. 15A) to the mounting plate (Fig. 15B) using two #12 - 14 x 1" hex head self- drilling screws (Fig. 15C). NOTE: To avoid cracking the mounting sensor housing, do not over-tighten the screws. Attach the mounting plate and sensor assembly (Fig. 16B) to the cross-member (Fig. 16A) using two #12 - 14 x 1"...

  • Page 12: Installing The Controller

    Installing the Controller NOTE: Prior to starting this portion of the installation, double check that all of the harnesses are properly and securely connected to the Power Tongue Jack, the stabilizer jack motors, leveling jacks, and remote leveling sensor. NOTE: The compartment where the controller will be installed must be protected from the elements and the controller MUST be installed in compliance with Recreational Vehicle Industry Association (RVIA) Gas Codes, since the controller connections are not spark-proof.

  • Page 13: Touch Pad Installation Options

    Touch Pad Installation Options Ground Control TT Lite comes with the Auto Leveling Control Touch Pad by default, but can be upgraded with the LCD Electronic Leveling Touch Pad based on individual OEM specifications.

  • Page 14: Installing The Lcd Electronic Leveling Touch Pad

    Installing the LCD Electronic Leveling Touch Pad NOTE: The LCD Electric Leveling Touch Pad can perform zero point, manual operation, and troubleshooting functions right from the touch pad. Determine the mounting location of the LCD Electronic Leveling Touch Pad. It should be mounted in a compartment on the side of the trailer so the operator will have a view of the coupler while using the touch pad.

  • Page 15: General Operation

    General Operation Prior to First System Operation Visually inspect the touch pad installed on the system. If the system is installed with the Auto Leveling Control Touch Pad (Fig 25), use of the OneControl Mobile App is required for use of advanced system functions and to establish the zero point. Prior to first system operation, navigate to the "Downloading the One Control Mobile App"...
