System and Safety Information
Failure to act in accordance with the following may result in death or serious personal injury. The use of
the Ground Control 3.0 leveling system to support the unit for any reason other than which it is intended
is prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as a “leveling”
system only and should not be used to provide service for any reason under the coach such as changing
tires or servicing the leveling system. Any attempts to change tires or perform other service while unit
is supported by the Ground Control 3.0 leveling system could result in damage to the 5th wheel and/or
cause death or serious injury.
Be sure to park the unit on solid, level ground. Clear all jack landing locations of debris and obstructions.
Locations should also be free of depressions. When parking the unit on extremely soft surfaces, utilize
load distribution pads under each jack. People and pets should be clear of coach while operating leveling
system. Never lift the unit completely off the ground. Lifting the unit so the wheels are not touching the
ground will create an unstable and unsafe condition.

Ground Control 3.0 OEM Installation Manual
Preparation
1. Remove all loose items from the front storage compartments of the 5th wheel.
2. Analyze the unit. Determine where the rear jack brackets, controller, and touch pad will be mounted
on the unit. The rear jack brackets should be mounted approximately 1 foot behind the rear axle
hanger and be aligned with each other. The controller should be mounted in the center of the unit
in compliance with RVIA Gas Codes as the controller connections are not spark-proof. The touch pad
should be mounted in a compartment on the side of the unit so that the operator will have a view of
the hitch pin while using the touch pad. The touch pad MUST also be protected from the elements.
NOTE: The landing gear will be installed to the frame of the unit by LCI.
Installation - Rear Jacks
1. Determine position and ground clearance requirements for the rear jacks (Fig. 1D). The rear jack
brackets (Fig. 1C) should be mounted approximately 1 foot behind the rear axle hanger and be aligned
with each other.
NOTE: When fully retracted, rear jacks should be equal to the departure angle or a minimum of 7" of ground
clearance.
2. Mark jack mounting bracket (Fig. 1C) locations on the main frame rail.
3. Clamp the bracket to the main frame rail (Fig. 1B) in the marked position.
4. Weld the bracket to the main frame rail (Fig. 1B).
5. Bolt the rear jacks (Fig. 1D) to the mounting brackets (Fig. 1C) using six bolts (Fig. 1E) and nuts (Fig. 1A)
per jack. Tighten the bolts to 90 lb.-ft. of torque.
6. Connect the wire harnesses to the rear jack motor wires and run the harnesses to the compartment
where the controller will be mounted.
NOTE: LCI recommends zip-tying the harnesses tight against the rear jack motors to prevent damage to the
harnesses.

Installation - Controller
NOTE: Prior to starting this portion of the installation, double check that all of the harnesses are properly
and securely connected to the rear jacks, landing gear, and rear sensor.
1. Measure the ceiling of the compartment where the controller will be placed and mark the center point
on the ceiling. The controller MUST be positioned directly in the center of the unit with the arrow on
the label of the controller facing the front of the unit (Fig. 7).
NOTE: Some 6-point controllers do not have orientation arrows for the front of the unit. When installing
those controllers, ensure that the port labeled "LEFT FRONT" is pointing to the left-hand front of the
unit. This will ensure proper orientation and function of the controller.
2. Using four #8 x 1” wood screws (Fig. 8B), attach the controller (Fig. 8A) to the ceiling of the
compartment, centered over the marked centerline of the compartment.
3. Attach the power and ground harnesses to the corresponding posts on the controller and then
connect them to the correct posts on the house battery.
4. Connect all jack harnesses to the appropriate connectors on the controller.

Installation - Touch Pad
1. Determine where to mount the touch pad. The touch pad should be mounted in a compartment on
the side of the unit so the operator will have a view of the hitch pin while using the touch pad.
2. Remove the faceplate of the touch pad (Fig. 9A) from the mounting bezel (Fig. 9B).
3. Cut a hole in the wall of the compartment 3 ⁄” wide by 2 ¾ ” high (Fig. 10) so the top and bottom
horizontal cuts are parallel to the floor of the compartment.

Operation
Basic Jack Operation
Landing gear jacks can be operated any time the system is “ON”. By pushing the “FRONT” button (Fig. 13G), both
front or landing gear jacks can be extended. By pushing either the "FRONT" and “LEFT” (Fig. 13H) or "FRONT" and
“RIGHT” (Fig. 13I) buttons, the individual front jacks can be extended. If the touch pad is put in the retract mode,
indicated by the orange illuminated LED next to the “RETRACT” button (Fig. 13D), the front jacks can be retracted
together by pushing the “FRONT” button (Fig. 13G) or individually by pressing “LEFT” (Fig. 13H) or “RIGHT” (Fig. 13I)
buttons, while simultaneously pressing the “FRONT” button (Fig. 13G).
NOTE: Middle jacks can only be operated in error mode. In order to engage middle jacks, press "LEFT" and
"RIGHT" buttons simultaneously.
The rear jacks can only be extended when the touch pad is in the manual mode. Once system is in manual mode,
pressing the “REAR” button (Fig. 13J) will extend both rear jacks at the same time. To extend individual rear jacks,
press the “LEFT” (Fig. 13H) or “RIGHT” (Fig. 13I) buttons while simultaneously pressing the “REAR” button (Fig. 13J),
depending on which jack needs to be operated. If the touch pad is put in the retract mode, indicated by the orange
illuminated LED next to the “RETRACT” button (Fig. 13D), the rear jacks can be retracted together by pushing the
“REAR” button (Fig. 13J) or individually by pressing either the “LEFT” (Fig. 13H) or “RIGHT” (Fig. 13I) buttons, while
simultaneously pressing the “REAR” button (Fig. 13J).
NOTE: If the rear jacks will not operate individually using the method described above, but they operate
properly when Auto Level is performed, the Twist Prevention Protection system has locked out the
operation to prevent damage to the frame of the unit.
Homing Jacks
1. Introduce an error - disconnect one of the hall effect sensor wires at the controller.
2. Attempt to operate the jack that is associated with the sensor wire that was disconnected. The touch
pad screen will display an error for that jack.
3. Reconnect the hall effect sensor wire. Manually extend all jacks down a minimum of 6 inches.
4. Press and hold the retract button until all of the jacks begin to retract. The jacks will retract until they
reach the hard current limit.
5. The jacks are now “homed.”
NOTE: If the jacks do not retract, an error should display on the touch pad screen. This is typically caused by
wiring interruption.
NOTE: In order to "home" jacks, middle jacks MUST also be extended. Refer to Basic Jack Operation for
middle jack operation.

Zero Point Calibration
The “Zero Point” is the programmed point that the unit will return to each time the Auto Level feature is used. The
“Zero Point” MUST be programmed prior to using the Auto Level feature to ensure the proper operation of the
system.
NOTE: Prior to starting this procedure, double check all connections on the controller, jacks, and touch pad.
1. Manually run the jacks to level the unit. This is best achieved by placing a level in the center of the unit
and leveling it both front to back and then side to side. (See “Basic Jack Operation” for instructions on
how to manually operate the system).
2. Once the unit is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button (Fig. 13G) five (5) times and then press
and release the “REAR” button (Fig. 13J) five (5) times.
4. The touch pad will flash and beep and the display will read “ZERO POINT CALIBRATION ENTER to set,
Power to Exit” (Fig. 14).
5. To set the current position as the zero point, press the “ENTER” button (Fig. 13C).
6. LCD display will read “Zero Point stability check” (Fig. 15).
7. LCD display will read “Zero point set successfully” once process is complete (Fig. 16).
8. The system will set this point as its level state and the touch pad will turn off.
