VOLTAGE REGULATION
The electronic voltage regulator controls the output of the generator by regulating the current into the exciter field.
The regulator has three screwdriver adjustable potentiometers that may be adjusted for voltage, stability and voltage
roll-off (U/F). The voltage regulator on the unit is adjusted before shipment from the factory. Contact Magnum Power
Products LLC for additional information before attempting to adjust the voltage regulator.
Note:
For units equipped with a Marathon D digital voltage regulator, please refer to the Marathon operating
manual provided with the unit.
CUSTOMER CONVENIENCE RECEPTACLES
The generator is equipped with five convenience receptacles. The large
receptacles are 240/120VAC twist-lock receptacles rated at 50A each. The
smaller receptacles are 120VAC duplex receptacles rated at 20A each with
ground fault circuit interrupt (GFCI) protection. These receptacles are not
routed through the main circuit breaker. Each receptacle has its own circuit
breaker, located directly above or next to the receptacle. Each breaker is sized
to the maximum rating of the corresponding receptacle.
Power to the recpetacles is available any time the generator
is running,
EVEN IF THE MAIN CIRCUIT BREAKER IS
“OFF/O”. MAKE SURE THAT ANY EQUIPMENT CON-
NECTED TO THE CONVENIENCE RECEPTACLES IS
TURNED OFF BEFORE TURNING THE BREAKERS ON.
Make sure that the voltage selector switches are in the
proper position and that the output voltage is correct for the
equipment that is connected to the receptacles. Improper
voltage may cause equipment damage or malfunction.
DERATING FOR ALTITUDE
All generator sets are subject to derating for altitude and temperature; this will reduce the available power for operation
of tools and accessories connected to the auxiliary receptacles. Typical reductions in performance are 2-4% for every
1000 ft. (305 m) of elevation and 1% per 10ºF (-12ºC) increase in ambient air temperature over 72ºF (22ºC).
REMOTE START TERMINAL BLOCK
The remote start terminal block is located just to the right of the three twist-lock convenience
receptacles. It provides a connection for installation of a remote start switch which will allow the
generator to be started by a remote dry-contact closure switch.
Before pressing the "AUTO" button, verify that the contacts on any remote switch linked to the
generator are
OPEN.
If the contacts on a remote switch are closed, the generator will crank and
start when "AUTO" is selected. Attach the switch leads to the two unused terminals on the generators
remote start block. For additional information on starting the generator, refer to
.
TRANSFER SWITCH
The generator neutral is bonded to ground when shipped from the factory. The bonding plate
will need to be removed when the generator is used as a standby power source. Installation
should be in compliance with National Electric Code (NEC), as well as any state and local
codes or regualtions.
CAUTION
Do not use 120V GFCI
outlets when generator at
480 or 600 volts. Equipment
damage or personal injury
may result.
CAUTION
Do not use 240V twist lock
outlets when generator at
