Cable Installation
Install the welding cables to your Vantage
1. The engine must be OFF to install welding cables.
2. Remove the flanged nuts from the output terminals
3. Connect the electrode holder and work cables to the weld
out-put terminals. The terminals are identified on the case
front.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding (the "work")
is properly connected to the work clamp and cable.
6. Check and tighten the connections periodically.
CAUTION
•
Loose connections will cause the output terminals to
overheat. The terminals may eventually melt.
•
Do not cross the welding cables at the output terminal
connection. Keep the cables isolated and separate from
one another.
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 can be reset
properly. See the MAINTENANCE section for more detailed
information on testing and resetting the GFCI.
The auxiliary power of the Vantage
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 11,500 watts Peak, 10,000 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 42amps.
The 240 VAC output can be split to provide two separate 120 VAC
outputs with a max permissible current of 42 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 12,500 watts peak,
11,000 watts continuous. The maximum current is 27 amps.
120 V Duplex Receptacles and GFCI
A GFCI 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 will trip, removing voltage from the output of the
receptacle. If a GFCI is tripped see the MAINTENANCE section for
detailed information on testing and resetting it. A GFCI should be
properly tested before each use.
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
322 / LE400 as follows.
®
322 / LE400 consists of two
®
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 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
322 / LE400 is suitable for temporary, standby or
®
emergency power using the engine manufacturer's recommended
maintenance schedule.
The Vantage
322 / LE400 can be permanently installed as a
®
standby power unit for 240 VAC, 3 wire, single phase, 40 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 14-50) 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.
