Standby Power Connections - Lincoln Electric VANTAGE 400 Operator's Manual

VANTAGE 400
is 50amps.
The 240 VAC output can be split to provide two separate 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 DUPLEX RECEPTACLES AND GFCI
A GFCI protects, the two 120V Auxiliary Power receptacles. A
GFCI (Ground Fault Circuit Interrupter) electrical receptacle is a
device to protect against electric shock should a piece of defec-
tive equipment connected to it develop a ground fault. If this situ-
ation should occur, the GFCI will trip, removing voltage from the
output of the receptacle. If a GFCI is tripped see the MAINTE-
NANCE section for detailed information on testing and resetting it.
A GFCI 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.
All auxiliary power is protected by circuit breakers.
The 120V has 20 Amp circuit breakers for each duplex recepta-
cle. 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 emer-
gency power using the engine manufacturer'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 premises 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 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.
