3.2 STARTING - STANDBY OPERATION

WARNING

Be aware of HIGH VOLTAGE supplied at the power plug or from the generator. When performing ser-

vice or maintenance procedures: ensure any two way communication is disabled in accordance with

the manufacturer’s instruction, ensure the Main Power Switch is in the OFF position and, whenever

practical, disconnect the high voltage source, lockout/tagout the receptacle and disconnect the neg-

ative battery connection. NEVER dis-assemble the generator: HIGH MAGNETIC FIELD INSIDE! This

field can interfere with cardiac implants such as pacemakers and defibrillators.

WARNING

Ensure the power plug is clean and dry before connecting to any electrical outlet / receptacle.

WARNING

Do not connect power plug to any electrical outlet without checking that it meets the 460/3/ 60

and 30 Amp electrical requirements of the unit.

3. Place the switch labeled ENGINE/

OFF/STANDBY in the STANDBY po-

sition.

2. Ensure the external power circuit breaker is off,

connect standby cable to unit and then turn the ex-

ternal power circuit breaker on.

1. Ensure the switch labeled ENGINE/OFF/

STANDBY is in the OFF position.

4. The unit will then perform a Self Test (refer to section

3.3) and start the unit automatically.
