Lincoln Electric VANTAGE 500 - Manual (Page 15)

STANDBY POWER CONNECTIONS
The VANTAGE® 500 is suitable for temporary, stand-
by or emergency power using the engine manufactur-
er’s recommended maintenance schedule.
The VANTAGE® 500 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.
• Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:
• The installation complies with the National
Electrical Code and all other applicable electri-
cal codes.
• The premises is isolated and no feedback into
the utility system can occur. Certain laws require
the premises to be isolated before the generator
is linked to the premises. Check your local
requirements.

AUXILIARY POWER RECEPTACLES
Start the engine and set the “IDLER” control switch to the
“High Idle” mode. Voltage is now correct at the recepta-
cles for auxiliary power. This must be done before a
tripped GFCI module can be reset properly. See the
MAINTENANCE section for more detailed information on
testing and resetting the GFCI module.
The auxiliary power of the VANTAGE® 500 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 13,000 watts Peak,
12,000 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 permissi-
ble current of the 240 VAC output 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 22,000
watts peak, 20,000 watts continuous. The maximum cur-
rent is 45 amps.
120 V DUPLEX RECEPTACLES AND GFCI MODULES
A GFCI Module protects the two 120V auxiliary power
receptacles.
A GFCI (Ground Fault Circuit Interrupter) 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 module will trip, remov-
ing voltage from the output of the receptacle. If a GFCI
module is tripped see the MAINTENANCE section for
detailed information on testing and resetting it. A GFCI
module 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.
All auxiliary power is protected by circuit breakers. The
120V has 20 Amp circuit breakers for each duplex recep-
tacle. The 120/240V Single Phase and the 240V Three-
Phases have a 50 Amp 3-pole Circuit Breaker that dis-
connects both hot leads and all Three Phases simultane-
ously.
