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.

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.
