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 properly.
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 equiva-
lent to volt-amperes at unity power factor. The max per-
missible 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 17,000
watts peak, 19,000 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 recepta-
cle.
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-Phase 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, stand-
by or emergency power using the engine manufactur-
er's 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 customer's 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 allowable - 10% of
rated voltage which may damage appliances or
other motor-driven equipment and may result in
overheating of the engine and/or alternator wind-
ings.
• 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 recep-
tacle on the case front.
