SAFETY WARNINGS AND PRECAUTIONS
When using Real Power, basic safety precautions should always be followed to reduce
the risk of personal injury and damage to equipment.
Read all instructions before using this system!
1. Observe work area conditions. Do not use electricity or power tools in damp or wet locations. Keep
work area well lighted. Do not use electrically powered tools in the presence of flammable gases or
liquids.
2. Keep unauthorized personnel and children away from the vehicle. The Real Power system contains
rotating components and lethal voltages. Only trained personnel should be allowed near the vehicle
while the system is operating.
3. Lethal voltage is present whenever the system is operating. Real Power generators can produce
voltages in excess of 480V.
4. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
5. Do not go under vehicle when System or engine is running. Do not work on or near
an exposed shaft while the engine is running.
6. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running
machines.
7. Do not start or stop the generator with a load connected. Unplug connected tools, appliances and
cords when not in use and prior to starting or stopping the System.
8. Check for damaged parts. Before using the Real Power system inspect it thoroughly. Make sure all
bolts are tight. The generator should be dry and free of debris.
9. Replacement parts and accessories. When servicing, use only identical replacement parts. Use of
any other parts will void the warranty. Replacement parts and service are available from Real Power.
You contact us by calling [phone]. Parts and accessories should be installed by qualified
technicians.
10. Do not operate a Real Power system if under the influence of alcohol or drugs. Read warning labels
on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there
is any doubt, do not operate the system.
11. Use proper size and type cable. Follow Local and National Electric Code guidelines when connecting
loads to the generator.

Rev. 22-05 7 of 26
ELECTRIC GENERATOR SAFETY PRECAUTIONS AND WARNINGS
When System is operating, lethal voltage is present!
1. The generator produces electrical current. Improper use can result in electrocution, injury or death.
Only a qualified technician should service or repair this generator.
2. The generator was designed to be used in a dry area. Use extreme caution when operating the
System in rain, snow, sleet, or damp conditions. Operating the System in such conditions is NEVER
recommended or encouraged. Moisture can carry electrical current and could cause electrocution.
3. If the generator is connected to a building, home, business, or any other electrical circuit normally
fed by utility power, steps must be taken to ensure that the generator output and the utility power
are isolated. Failure to isolate the systems could result in personal injury or death to those working
around these circuits. Any connection in this regard must only be done in accordance with NEC or
the locally applicable Electrical Code.
4. Do not exceed the generator's rated capacity. The total electrical loads must be added to determine
the total electrical load. If the electrical appliance does not list the wattage rating, you can calculate
it by multiplying amps times voltage (amps x voltage = watts).
5. Do not tamper with the drive engine-governed speed. The generator is designed to operate at a set
speed. Changing this speed will change the output voltage and frequency. Increases in speed will
damage rotating parts of the generator. Slower speeds may damage the generator or appliances
connected to the generator due to low voltage.
6. Always follow national and local safety codes.
7. Do not start or stop the System with equipment connected and turned on.
8. Do not operate your Real Power equipped vehicle in an enclosed area due to the carbon monoxide
fumes produced. The fumes are colorless and odorless and are deadly.
9. Never handle electrical equipment or cords while standing in water.
10. Only use 3-prong, grounded extension cords.
11. Keep fingers, hands, cords and other loose items away from the spinning shafts and pulleys that are
rotating under your Real Power equipped vehicle.
12. Never refuel or add fuel to your vehicle or remove the fuel cap whenever the System is operating.
13. Read, understand, and follow all safety precautions in your vehicle owner’s manual prior to running
the System.
COMMON SENSE AND CAUTION PREVAIL
The warnings, cautions, and instructions discussed in this manual cannot cover all possible conditions
and situations that may occur. It must be understood by the operator that common sense and caution
are factors that cannot be built into this product, but must be supplied by the operator.

REAL POWER SYSTEM OVERVIEW
Real Power generator systems are manufactured exclusively for use with the power take off (PTO) of a
Class 4 or larger work tuck with diesel engine and automatic transmission. While in a parked, stationary
mode, the engine of the truck provides rotational power to the generator via the PTO attachment,
turning it at a constant 1800 RPM to produce 60Hz. The truck engine RPM, power output, and torque
are controlled automatically by the truck ECM and TCM with no input required from the user.
Power from the generator is typically routed to a remote electrical panel box, located in the body of the
truck, which contains both the low voltage DC control signals and the high voltage AC power distribution
with main breaker, sub breakers, and either plug-in receptacles or hard wire lines for other equipment.
While the standard RP015 generators ship with dedicated 240/120V 1Φ wiring, the RP036 systems
provided by Real Power have an industry-standard 12 wire reconnectable configuration, capable of 480V
3Φ, 208V 3Φ, or 240/120V 1Φ depending on how they are tapped. All Real Power generators are
equipped with a proprietary set of enhancements to make them robust against difficult road
environments.
A diagram showing the connection options is provided with each system. All connections to the
generator should be done in accordance with NEC guidelines and any other applicable electrical code for
your area.

DSR REGULATOR DIAGRAM
Notes:
All Real Power generators are 4-pole, brushless, 1800 rpm AC generators with digital voltage regulation. The regulators are located inside the main connection panel and
include 4 potentiometer adjustments. The only adjustment that should ever be made to the regulator once it has been installed is the VOLT setting. All others are set by the
factory.

OPERATION
Custom applications may have slightly different instructions. If you have any questions contact
your installer or Real Power.
Warm Up and Cool Down
The generator should be allowed to warm up before use when the weather is cold. This allows the
system to reach operating temperature before the components are stressed with a load. For
temperatures at or below 32°F the system should be allowed to warm up for approximately 10 minutes.
When the weather is hot or the generator is used under heavy load the system needs time to cool
down. This can be done by leaving the truck idling for 10 minutes with the PTO engaged allowing the
integrated generator fan to cool down the generator. Approximately a 10 minute cool down period is
recommended if the air temperature is greater than 80°F or if the generator is used at greater than 80%
load.
Starting the Generator
1. Verify that there is no load on the generator. All equipment should be unplugged or off.
2. Confirm that the E-Stop switch on the panel is reset (pulled out).
3. Ensure truck is in Park
4. Set Parking Brake
5. Turn the Ignition Key if vehicle is not running. (Truck does not need to be turned off and on.)
6. Set upfitter switch labeled “PTO”
PTO Clutch will automatically engage. Engine RPM will automatically ramp to the correct speed
and hold there.
7. Allow the generator to warm up if necessary. (see above Warm Up and Cool Down section)
8. The generator is ready to supply power.
Stopping the Generator
The normal procedure for shutting down the generator is as follows:
1. Remove all loads from the generator. All equipment should be unplugged or in off position.
2. Return PTO switch to off.
3. Reset Parking Brake.
4. Allow the generator a few seconds to spin down and come to a rest before moving the vehicle.

Resettable PTO Interrupts [Does Not Require System to be Turned Off and On Again]
The command signal for the vehicle to run PTO mode and engage the generator passes through all
three of these checks in series. Removing any one of them in will shut of the generator system. If
the truck is running, it will immediately restart the generator once the interrupt is restored.
1. PTO Upfitter Switch
2. Real Power Emergency Stop Button
3. Generator Over-Temperature Switch
Note: The order in which these signals are engaged or disengaged does not affect operation. For example, if the
Over Temperature Switch shuts the PTO off but the PTO dash switch remains engaged with the engine on,
the generator system will automatically come back on (whether intentional or not) once the temperature
switch resets. The same is true for the Emergency Stop, but it should be noted: Real Power recommends
always using the PTO upfitter switch to operate the generator rather than the emergency stop.
Stationary Elevated Idle Control (SEIC) program interrupts
[Requires System to be Turned Off and On Again]
In addition to the PTO enable command signal, there are a number of fault conditions that will cause the
truck shut down the PTO and high idle internally. Once they occur, the command signal must be cycled
by switching the PTO switch off and on again. Fault conditions include:
1. Pressing the foot brake pedal
2. Shifting out of Park
3. Releasing the Parking Brake
4. Pressing the accelerator pedal
5. Vehicle rolling / motion
6. Over temperature of the engine or transmission coolant
REAL POWER Secure Truck Feature
All Real Power generators installed on Ford and Dodge trucks come equipped with the Real Power
Secure Truck feature, which allows the PTO, once engaged, to continue to run even after the ignition
key is turned off and removed. At any time that the generator is running, the operator may remove
the key from the truck and lock the doors behind him, allowing him to work on power equipment
hundreds of feet away without concern for the security of the vehicle.
PTO operation will continue unless and until any one of the above interrupts is engaged or a fault
condition occurs. At that time, the vehicle will shut down completely, including the engine and be
inoperable until the key is put into the ignition and turned back to start up. Alternatively, an
operator can put the key back in the ignition while the generator is still running and return it to the
RUN position. Then the truck will not shut down when the PTO is turned off.
Periodic Cycling
The Real Power generator system should be started and ran for 10 minutes once every 30 days if not
used regularly. This will cycle the shaft and bearings and keep them lubricated.

Rev. 22-05 17 of 26
MAINTENANCE
In order to ensure proper functioning of your Real Power Generator and prevent possible damage to
your vehicle, it is paramount to conduct regular checks and perform preventative maintenance actions
on your generator, the driveline, and PTO. Make sure to keep records of maintenance activities that are
conducted. Failure to properly maintain your generator system could void the warranty.
Before performing any maintenance on any portion of the Real Power generation system, the vehicle
must be off with the keys removed from the ignition and the generator and all parts of the vehicle
must be allowed to cool down after use.

1. Real Power drivelines connecting the PTO to the Generator are generally equipped with Sealed,
Non-Serviceable U-joints which do not have grease fittings. However, 4x4 vehicles have a
driveline with a CV joint attached to the back of the transfer case which does have a greaseable
ball joint in the center.
This joint must be lubricated monthly or every 50-60 hrs, whichever is more frequent. To do so,
use a needle-nose grease point to inject directly into the fitting at the center of the CV joint.
From the manufacturer:
Dana recommends lubrication with Spicer ultra-premium synthetic grease, Chevron Ultra-Duty EP-2, or a compatible
lithium-based grease meeting NLGI Grade 2 and ASTM D4950 LB specifications. Spicer ultra-premium synthetic grease
is available in 10-packs of 14-oz. tubes (SPL1051) and 1-gal. pails (SPL1052)

18 of 26 Rev. 22-05
Note: In some applications, 4x4 drivelines use greasable U-joints along with the greasable ball
joint. If you have a 4x4 truck, familiarize yourself with all U-joints and lubricate them on the same
schedule if they are not sealed.
2. All Real Power systems have a slip joint in the center with its own zerk fitting. This must be
lubricated every 100hrs or 1 month.
3. To ensure the safe and reliable operation of the drive shafts, the U-joints must be inspected
monthly or every 100 hours. Visually inspect the 4 cups of each U-joint for signs of heat
damage, slop, or water penetration. Snap rings should all be snug in place without any visible
cracks. The drive joint should have no play in it and be able to rotate smoothly by hand.
Above: 1. A new U-joint. 2. Good U-joint – clean and sealed with smooth rotation. 3. Bad U-joint – Rusted out with
gritty motion and/or slop in the joints.
Check for a characteristic pattern of grease spatter which could indicate that the seals are failing
and grease is leaking out. NOTE: if your vehicle has greasable U-joints and a CV joint, it is normal
to have some amount of spatter from those fittings.

Zerk Fitting

Rev. 22-05 19 of 26
Similarly, the carrier bearing mount should be firmly holding the driveline collar in place without
slop or free motion. Check seals for separation or degradation.
Above: 1. New Carrier Bearing. 2. Bad carrier bearing with torn rubber and displaced front seal.
If any issues are found, the U-joints or drive line may need to be replaced. Contact Real Power
for help determining a course of action.
4. All fasteners have been marked with tamper evident paint. Every 100 hrs or 1 month, check all
marks for signs of movement or loosening. If found, immediately retighten and make a note to
track possible future issues.
NOTE: Take special notice of the PTO mounting bolts. If PTO comes partially loose during operation,
catastrophic failure to transmission could occur.
5. When the truck is off, the driveshaft should rotate freely and smoothly. Every 100hrs or 1
month, rotate the drive shaft by hand and check the PTO and generator for smooth, even
rotation. Take note of bearing friction, noise, or roughness and contact Real Power in the event
of a substantial or worsening noise and/or roughness on either end of the drive line.

20 of 26 Rev. 22-05
6. The air filter on the generator should be periodically cleaned. Inspect the air filter every 300
hours and make sure it is not clogged.
i. Remove the rear dust cover on the generator with 10mm socket.
ii. Wash the filter with warm water and mild soap.
iii. Allow the filter to dry.
iv. Re-install the filter and dust cover.
7. Once per year, conduct a thorough inspection of the generator. Look for signs of loosening
hardware, signs of wear or abrasion on the conduit leaving the generator, or rubbing between
the generator fan shroud or output box and the truck’s driveline.
