The AIR VANTAGE® 500 KUBOTA is suitable for
temporary, standby or emergency power using the
engine manufacturer’s recommended maintenance
schedule.
The AIR VANTAGE® 500 KUBOTA can be perma-
nently 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 adapt-
ed 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.
