AUXILIARY POWER RECEPTACLES
Start the engine and set the "IDLER" control switch to
the "High Idle" mode. Voltage is now correct at the
receptacles for auxiliary power. This must be done
before a tripped GFCI receptacle can be reset proper-
ly. See the MAINTENANCE section for more detailed
information on testing and resetting the GFCI recepta-
cle.
The auxiliary power of the VANTAGE 400 consists of
two 20 Amp-120 VAC (5-20R) duplex receptacles with
GFCI protection, one 50 Amp 120/240 VAC (14-50R)
receptacle and one 50 Amp 240VAC Three-Phase (15-
50R) receptacle.
The auxiliary power capacity is 12,000 watts Peak,
11,000 Watts Continuous of 60 Hz, single phase
power. The auxiliary power capacity rating in watts is
equivalent to volt-amperes at unity power factor. The
max permissible current of the 240 VAC output is
50amps.
The 240 VAC output can be split to provide two sepa-
rate 120 VAC outputs with a max permissible current
of 50 Amps per output to two separate 120 VAC
branch circuits (these circuits cannot be paralleled).
Output voltage is within ± 10% at all loads up to rated
capacity.
The Three-Phases auxiliary power capacity is 19,000
watts peak, 17,000 watts continuous. The maximum
current is 45 amps.
120 V GFCI DUPLEX RECEPTACLES
A GFCI (Ground Fault Circuit Interrupter) electrical
receptacle is a device to protect against electric shock
should a piece of defective equipment connected to it
develop a ground fault. If this situation should occur,
the GFCI will trip, removing voltage from the output of
the receptacle. If a GFCI receptacle is tripped see the
MAINTENANCE section for detailed information on
testing and resetting it. A GFCI receptacle should be
properly tested at least once every month.
The 120 V auxiliary power receptacles should only be
used with three wire grounded type plugs or approved
double insulated tools with two wire plugs. The current
rating of any plug used with the system must be at
least equal to the current capacity of the associated
receptacle.
NOTE: The 240 V receptacle has two 120 V circuits,
but are of opposite polarities and cannot be paralleled.
INSTALLATION
All auxiliary power is protected by circuit breakers.
The 120V has 20 Amp circuit breakers for each
duplex receptacle. The 120/240V Single Phase and
the 240V Three-Phases have a 50 Amp 3-pole Circuit
Breaker that disconnects both hot leads and all Three
Phases simultaneously.

STANDBY POWER CONNECTIONS

The VANTAGE 400 is suitable for temporary, standby
or emergency power using the engine manufacturerʼs
recommended maintenance schedule.
The VANTAGE 400 can be permanently installed as
a standby power unit for 240 VAC, 3 wire, single
phase, 50 amp service. Connections must be made
by a licensed electrician who can determine how the
120/240 VAC power can be adapted to the particular
installation and comply with all applicable electrical
codes.
• Install the double-pole, double-throw switch
between the power company meter and the premis-
es disconnect. Switch rating must be the same or
greater than the customerʼs premises disconnect
and service over current protection.
• Take necessary steps to assure load is limited to
the capacity of the generator by installing a 50
amp, 240 VAC double pole circuit breaker.
Maximum rated load for each leg of the 240 VAC
auxiliary is 50 amperes. Loading above the rated
output will reduce output voltage below the allow-
able - 10% of rated voltage which may damage
appliances or other motor-driven equipment and
may result in overheating of the engine and/or
alternator windings.
• Install a 50 amp, 120/240 VAC plug (NEMA Type
14-50P) to the double-pole circuit breaker using
No. 6, 4 conductor cable of the desired length. (The
50 amp, 120/240 VAC plug is available in the
optional K802R plug kit or as part number T12153-
9.)
• Plug this cable into the 50 Amp, 120/240 Volt
receptacle on the case front.
