LINE VOLTAGE ELECTRICAL SYSTEM
ONAN PTO GENERATOR
The vehicle shall be equipped with an Onan Protec PTO generator system with a capacity of 15,000 watts at
120/240 VAC, 125/62 amps, single phase. Current frequency shall be stable at 60 hertz.
The transmission’s PTO port and PTO, or the split shaft PTO, and all associated drive shaft components shall be
rated to support the continuous duty torque requirements of the generator’s continuous duty rating as stated on
the power source nameplate.
Where the generator is driven by the chassis engine and transmission through a split shaft PTO, the driving
compartment speedometer shall register when the generator drive system is engaged.
Where the generator is driven by the chassis engine and transmission through a split shaft PTO and a chassis
transmission retarder is furnished, it shall be automatically disengaged for generator operations.
The direct drive generator shall be mounted so that it does not change the ramp breakover angle, angle of
departure, or angle of approach as defined by other components, and it shall not extend into the ground clearance
area.
The direct drive generator shall be mounted away from exhaust and muffler areas or provided with a heat shield
to reduce operating temperatures in the generator area.
GENERATOR BONDING
A minimum of four (4) 16" x 2 gauge copper ground straps shall be bolted to body sub-frame and chassis sub-
frame for proper bonding of high voltage system. The conductor shall have a minimum amperage rating, as
defined in 310.15, “Ampacities for Conductors Rated 0–2000 Volts,” of NFPA 70, of 115 percent of the rated
amperage on the power source specification label.
GENERATOR ENGAGEMENT
A “Generator Engaged” indicator shall be provided in the driving compartment to indicate that the generator shift
has been successfully completed.
An “OK to Operate Generator” indicator shall be provided in the driving compartment to indicate that the generator
is engaged (if not always engaged), the transmission is in the proper gear (if required, automatic transmissions
only), and the parking brake is engaged (if applicable).
An interlock system shall be provided to prevent advancement of the engine speed in the driving compartment or
at any operator’s panel unless the parking brake is engaged, and the transmission is in neutral or the output of the
transmission is correctly connected to a pump or generator instead of the drive wheels.
WARRANTY PERIOD
Provided such goods are operated and maintained in accordance with Onan's written instructions, Onan warrants
that the Protec YDCR series PTO generators shall be free from defects in material and workmanship for a period
of five (5) years or one thousand (1,000) hours, whichever comes first, from the date of delivery to the first
purchaser.
