Instrumentation
If the power source is rated at less than 3 kW, a “Power On” indicator shall be provided. If the power source is
rated at 3 kW or more but less than 8 kW, a voltmeter shall be provided.
If the power source is rated at 8 kW or more, the following instrumentation shall be provided at an operator’s
panel:
 Voltmeter
 Current meters for each ungrounded leg
 Frequency (Hz) meter
 Power source hour meter
The instrumentation shall be permanently mounted at an operator’s panel. The instruments shall be located in a
plane facing the operator. Gauges, switches, or other instruments on this panel shall each have a label to indicate
their function.
The instruments and other line voltage equipment and controls shall be protected from mechanical damage and
not obstructed by tool mounting or equipment storage.
An instruction plate(s) that provides the operator with the essential power source operating instructions, including
the power-up and power-down sequence, shall be permanently attached to the apparatus at any point where such
operations can take place.
Operation
Provisions shall be made for placing the generator drive system in operation using controls and switches that are
identified and within convenient reach of the operator.
Where the generator is driven by the chassis engine and engine compression brakes or engine exhaust brakes
are furnished, they shall be automatically disengaged for generator operations.
Any control device used in the generator system power train between the engine and the generator shall be
equipped with a means to prevent unintentional movement of the control device from its set position in the power
generation mode.
If there is permanent wiring on the apparatus that is designed to be connected to the power source, a power
source specification label that is permanently attached to the apparatus at the operator’s control station shall
provide the operator with the information required.
The power source, at any load, shall not produce a noise level that exceeds 90 dBA in any driving compartment,
crew compartment, or onboard command area with windows and doors closed or at any operator’s station on the
apparatus.
Power Supply Assembly
The conductors used in the power supply assembly between the output terminals of the power source and the
main over current protection device shall not exceed 12 ft (4 m) in length.
All power supply assembly conductors, including neutral and grounding conductors, shall have an equivalent
amperage rating and shall be sized to carry not less than 115 percent of the amperage of the nameplate current
rating of the power source.
If the power supply assembly connects to the vibrating part of a generator (not a connection on the base), the
conductors shall be flexible cord or other fine-stranded conductors enclosed in metallic or nonmetallic liquid tight
flexible conduit rated for wet locations and temperatures not less than 194°F (90°C).
