Introduction
This manual provides instructions for operating the Lippert Power Step 2.0, which are equipped with a step
lockout switch, control unit and permanent magnet motor onto a motorized coach.
The control unit is a current sensor as well as a switching device. When the motor assembly moves the step
tread to its extended position, or stops moving because of an obstruction such as a curb or the binding of a
damaged or bent step frame, the motor draws a larger amount of current. The control unit senses the larger
current draw and shuts off the power to the motor.
Control units are equipped with an ignition override system. This system is designed so the vehicle will
not be driven with the step in the extended position. When the step is locked in the extended position,
the door closed, and the ignition is turned on, the ignition override system will engage and the step will
automatically retract.
The Auto Extend feature is another safety feature designed to extend the step when the door is opened for
the first time after the vehicle ignition is turned off, regardless of the position of the step switch.
NOTE: Refer to vehicle OEM owner’s manual (or OEM Requirements) which will provide switch position of
“on” or “off” for the step lock position.

The "WARNING" symbol above is a sign that a procedure has a safety risk involved and may cause
death or serious personal injury if not performed safely and within the parameters set forth in
thismanual.
Failure to follow instructions provided in this manual may result in death, serious personal injury
and/or severe product and property damage, including voiding of the component warranty.
Always wear eye protection when performing service, maintenance or installation procedures.
Other safety equipment to consider would be hearing protection, gloves and possibly a full face
shield, depending on the nature of the task.
The “CAUTION” symbol above is a sign that a safety risk is involved and may cause personal injury
and/or product or property damage if not safely adhered to and within the parameters set forth
in this manual.
Safety
Read and understand all instructions before installing or operating this product. Adhere to all safety labels.
This manual provides general instructions. Many variables can change the circumstances of the instructions,
i.e., the degree of difficulty, operation and ability of the individual performing the instructions. This
manual cannot begin to plot out instructions for every possibility, but provides the general instructions,
as necessary, for effectively interfacing with the device, product or system. Failure to correctly follow the
provided instructions may result in death, serious personal injury, severe product and/or property damage,
including voiding of the LCI limited warranty.
Moving parts can pinch, crush or cut. Keep clear and use caution.
The coach MUST be supported per manufacturer's specications before working underneath.
Failure to do so may result in death or serious injury.

Operation
If the vehicle is driven with the step in the extended position, there is the possibility of causing major
damage to both the step and the coach. Always make sure that the step is fully retracted before traveling. If
the step is left extended and strikes an obstruction while the vehicle is moving, major damage to both the
step and the vehicle could result.
Stepping on a partially extended step may cause damage to the step frame. Do not use the step until
the step is fully extended.
If the vehicle is driven with the step in the extended position, product and/or property damage
mayoccur.
NOTE: If the yellow wire from the 4-way connector is NOT connected to an ignition power source, the
ignition safety system will be inoperative and the step will remain in the extended position. In this
case, the override switch MUST be turned off for the step to retract.
NOTE: If the yellow wire from the 4-way connector is not connected to an ignition power source, the step
will NOT retract with the step in the override "on" position when the door is closed and the ignition
is on.
1. Open the entrance door then turn the step override switch to the "off" position.
A. Close the door.
I. The step should retract and lock in the up position.
II. The under-step light will be off.
B. Open the door.
I. The step should extend and lock in the down position.
II. The under-step light will be on.
NOTE: The under-step light is on when the step is extended and off when the step is retracted. If the coach
door/screen door is left open, the light will turn off after five minutes.
2. Turn the step override switch to the "on" position.
A. The step should remain in the extended position when the entry door is opened and closed.
B. The under-step light will turn off when the door is closed and on when the door is open.
3. With the step override switch turned on, the step extended and the entrance door closed, turn the
vehicle ignition on.
A. The ignition override system will go into effect.
B. The step will automatically retract.
NOTE: If the yellow wire from the four-way connector is not connected to an ignition power source, the
ignition safety system will be inoperative and the step will remain in the extended position. In this
case, the step override switch MUST be turned off for the step to retract.
4. Turn the vehicle ignition off and open the door.
A. The step will extend and lock in the down position. This is the Auto Extend feature.
B. When the vehicle ignition is turned on, the step will activate with the door movement, regardless
of the step override switch position.

Troubleshooting
What is Happening Why? What Should Be Done?
Battery drain. Step control unit not
shutting off.
1. Remove the 4-way and 2-way connector.
2. Place a voltmeter between the red and yellow motor wires at
the 2-way connector.
3. Reconnect the 4-way connector.
4. Turn the step lockout switch to the "on" position.
5. If any voltage registers on the meter for more than five
seconds, the control unit is not shutting off and may be
defective.
6. Switch the voltmeter leads back and forth between the red and
yellow motor wires to make sure no voltage registers.
• If any voltage registers, disconnect the 4-way connector to
keep the step motor from overheating.
• If zero voltage is present, the control unit has shut off and is
normal.
Step does not work.
Low supply voltage.
Check battery voltage and condition.
• Battery must have a no-load voltage of approximately 12.6 volts.
• Make sure the battery connections are clean and secure.
• Recharge or replace the battery, then retest the step for proper
operation.
Poor ground connections. Clean and tighten all ground connections.
Inspect ground wires for cuts and nicks, replace as necessary.
Step's control-to-vehicle
ground connection lost.
Step operates erratically.
Low supply voltage.
Check battery voltage and condition.
• Battery must have a no-load voltage of approximately 12.6 volts.
• Make sure the battery connections are clean and secure.
• Recharge or replace the battery, then retest the step for proper
operation.
Poor ground connections. Clean and tighten all ground connections.
Inspect ground wires for cuts and nicks, replace as necessary.
Converter output
inadequate.
Check converter output. Converter MUST be capable of
producing a minimum of 30 amps for proper step operation.
Converter improperly
filtered for clean DC voltage. Contact converter manufacturer.
Maintenance
Step Assembly Lubrication
Clean all mud, salt, and road grime from the step before lubricating. Lubricate all moving parts every 30 days
with a good quality moisture and heat resistant penetrating grease.
NOTE: Silicone lubricants and WD-40® are not recommended for use. They evaporate and dry the mating
surfaces, which leaves them vulnerable to the elements.
Maintain clean, dry electrical connections at the 2-way and 4-way connectors and any butt connections
leading from the 4-way connector to the vehicle. A small dab of dielectric grease at the connections, and
replacing corroded butt connections with heat shrink type crimp style automotive connectors, will help
maintain a good electrical source for the step.
Maintenance In A Salt Environment
When exposed to a salt environment, routinely spray the step with fresh water to maintain the step's finish.
