AIR VANTAGE® 500 CUMMINS

2. Take necessary steps to assure load is limited to the capacity
of the AIR VANTAGE® 500 by installing a 50 amp, 240 VAC
double pole circuit breaker. Maximum rated load for each leg
of the 240 VAC auxiliary is 50 amps. 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 AIR
VANTAGE® 500 engine.
3. 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.)
4. Plug this cable into the 50 Amp 120/240 Volt receptacle on the
AIR VANTAGE® 500 case front.
