5. The lights require a warm up period of 5-15 minutes before they reach full output. If the lights are shut down,
they require a cool down period of approximately 10 minutes before they can be switched on again.
6. The light tower uses four 1000W bulbs. When checking or replacing the bulbs, wipe them with a clean cloth to
avoid leaving any grease, oil residue or fingerprints on the glass. Any residue can create a hot spot on the bulb,
causing premature bulb failure.
CAUTION
Bulbs become extremely hot when in use. Allow bulb fixture to cool 10-15 minutes before
handling or lowering the mast.
VOLTAGE REGULATION
Units are equipped with an electronic voltage regulator. The voltage regulator controls the output of the generator
by regulating the current into the exciter field. The voltage regulator is adjusted before shipment from the factory.
Contact Magnum Power Products LLC for additional information before attempting to adjust the voltage regulator.
DERATING FOR ALTITUDE
All units are subject to derating for altitude and temperature; this will reduce the available power for operating tools
and accessories connected to the receptacles. Typical reductions in performance are 2-4% for every 1000 ft (305
m) of elevation and 1% per 10ºF (5.6ºC) increase in ambient air temperature over 72ºF (22ºC).
WET STACKING
The unit is powered by a diesel engine. Diesel engines are susceptible to wet stacking if lightly loaded. Wet stacking
occurs when an engine is run at less than 30% of its full load capacity, causing unburned fuel to accumulate in the
exhaust system. Wet stacking can be detected by continuous black exhaust when the unit is under a constant load.
It can also cause fouling of injectors and buildup on engine valves. Diesel engines operate properly when applied
loads are between 30% and 100% capacity. Appropriate generator sizing is determined by the anticipated load. If
the unit is in a wet stack condition, load the unit heavily for five hours or until the exhaust is clear.
RECEPTACLE PANEL
The receptacle panel is equipped with six receptacles for
running accessories or tools from the generator. Power
is supplied to the receptacles any time the engine is
running and the main circuit breaker is switched to the
“ON/I” position. The standard receptacle panel is
equipped with two of each of the following receptacles:
1. 240V/30A Twist-lock
2. 120V/20A GFCI
3. 240V/50A Twist-lock
Should the main breaker trip, remove some of the load
to the receptacles before turning them back on.
Each receptacle has an individual circuit breaker which is located behind the receptacle panel. The breakers are
labeled with the corresponding amperage for the receptacle they protect.
With all of the lights off, the full generator output may be used with the receptacles.
Note: To ensure proper grounding, anytime the generator is providing power to any equipment or load panels that
do not have a grounded plug, a ground wire MUST BE added between the equipment and the grounding stud on
the receptacle panel per any local, state or National Electrical Code (NEC) and guidelines.
