Introduction
INTRODUCTION
The Kenworth Clean Power System
The Kenworth Clean Power System is a battery-powered sleeper climate
control system with the capability to provide engine-off heating and cooling, plus 120-Volt AC accessory power to drivers for up to 10 hours. To
recharge the cooling and electrical capacity, the truck must be driven or
connected to shore power.
The Kenworth Clean Power System sleeper heating and air conditioning
system is an independent system from the cab heating and air conditioning
system. Both the controls and the heat and cooling sources are different.
Kenworth Clean Power System features include:
Compliance with all state and federal anti-idling regulations.
Engine-off sleeper heating, cooling, and 120-Volt AC power.
No engine noise or vibration.
Improved fuel economy.

Electric Power System
Charging instructions for the Kenworth Clean Power System is as follows:
ELECTRIC POWER SYSTEM
WARNING! Do not attempt to jumpstart the vehicle. The electrical charging system used for the
Kenworth Clean Power System is different than
normal charging systems. Failure to adhere to
the proper charging procedure could lead to serious injury or vehicle damage. Refer to the charging instructions located on the top of the main
battery box cover or in the Kenworth Clean Power
operator’s manual supplement/service manual.
Do not attempt to jumpstart the vehicle. If you have a battery problem, it is
best to contact an authorized Kenworth repair facility or a reputable towing
service. When you do, inform them of the charging instructions and the
wiring schematic on page 10.
Vehicles equipped with the Kenworth Clean Power System have battery
configurations that are different than traditional vehicles. These vehicles
have two different sets of batteries; the Main Batteries and the Starter Batteries.

Electric Power System
The Main Batteries are located behind the sleeper, on the driver’s side.
They power all electrical systems on the vehicle EXCEPT the starter motor.
The Starter Batteries are located below the cab, on the driver’s side, where
the vehicle’s batteries have traditionally been located. They power the
starter motor.
NOTE: The starter relay and other engine controls
rely on the Main Batteries for power; therefore, the
Starter Batteries can be fully charged and the Start
er Motor will not crank if the Main Batteries are not
charged. Do not jump start the Starter Batteries without checking the Main Battery voltage first.
A DC/DC charger, also located below the cab on the driver’s side, serves to
isolate the starting batteries from the main batteries and provides charge to
the starting batteries to maintain them at a minimum of 12-Volt.
NOTE: The DC/DC charger will only be activated
when either the truck is running or the truck is at
tached to a 120-Volt AC electrical supply and the key
is in the IGN position.
1. Check battery voltmeter gauge on dash to ensure main battery voltage
is at least 9.5-Volt.
2. If not, plug into 120-Volt AC electrical supply to charge main batteries or
attach battery charger to charging terminals located in back of sleeper.
3. Once main battery voltage is at least 9.5-Volt, attempt to start the truck.
If truck does not start, ensure that starter battery voltage is at least 12-Volt
(check at starter using voltmeter.)
4. If not, charge the starter batteries with an external battery charger.
5. Once starter battery voltage is at least 12-Volt, attempt to start the truck.
If truck does not star t, the truck should be towed to the nearest authorized
Kenworth dealer.
Refer to the Troubleshooting Section on page 33 for more details.

Electric Power System
Disconnect Instructions
Prior to servicing the vehicle, disconnect the electrical system as follows:
1. Unplug connection to 120-Volt AC electrical supply.
2. Turn disconnect located at cab floor to OFF position.
3. Turn disconnect located on main battery box (located driver’s side, rear
of sleeper) to OFF position.
NOTE: Do not connect any accessories directly to
the starting batteries. Accessory loads should be
connected to the main batteries only.
Refer to Kenworth Clean Power operator’s manual
supplement/service manual for further details. If you
are uncomfortable with performing the procedures
above, contact the nearest authorized Kenworth
dealer.

Electric Power System
WARNING! Electric Shock Hazard. 120-Volt AC
power present. Only a trained technician should
work on the 120-Volt AC system. Turn all disconnects (both at the cab floor and on the main
battery box located on the driver’s side, back of
sleeper) to the OFF position and unplug the 120Volt AC electrical supply before servicing any
part of the vehicle’s electrical system.
WARNING! An improperly maintained 120-Volt AC
electrical system can cause fires and electrical
shocks that may lead to personal injury or property damage. Regularly inspect 120-Volt AC
Charging using Shore Power (120-Volt AC Electrical
Supply)
Shore Power
Connection
electrical wiring connectors for damage. Always
use a properly grounded 20 Amp AC extension
cord that is no longer than 25 ft. and a 20 Amp AC
protected power source with a grounding conductor when connecting to a 120-Volt AC electrical supply.
WARNING! The Shore Power electrical system
can cause fires resulting in personal injury and/
or property damage if not properly maintained.
Regularly inspect the Volt AC truck wiring, AC extension cord, plugs, and connectors for damaged
or frayed wiring. Do not use the Shore Power
system if there are any signs of problems. Contact your authorized Kenworth Dealer if you are in
need of repairs or information.
Attach the 120-Volt AC extension cord to a 20 amp protected circuit until system voltage is restored. The Shore Power electrical connection is
located on the rear of the Main Battery Box. Make sure that the Inverter/
Charger Switch is in the ON position and that the circuit breaker on the
Protection Unit box has not been tripped. The Shore Power Lamp on the
Sleeper Control Panel will illuminate green and the Inverter/Charger Lamp
will illuminate orange.
Normal system voltage is 13.5 to 14.6 -Volts. Typically the Main Batteries
must reach at least a 9.5-Volt charge to power the engine controls necessary to start the engine.
