ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH
High voltage in transfer switch components pres-
ents serious shock hazards that can result in severe
personal injury or death. Read and follow these in-
structions.
Keep the transfer switch cabinet cover secured with
the provided mounting hardware. Only authorized
personnel are allowed to access the inside of the
cabinet.
Due to the serious shock hazard from high voltages
within the cabinet, all service and adjustments to
the transfer switch must be performed only by a
trained and experienced electrician or an autho-
rized Cummins Onan service representative.
If the cabinet must be opened for any reason:
1. Disconnect the AC utility power from the trans-
fer switch by opening the circuit breaker in the
main panel that feeds the transfer switch.
2. Move the operation selector switch on the gen-
erator set to Stop/Off.
3. Disconnect the negative (−) cable from the
generator set starting batteries.
GENERAL PRECAUTIONS
Place rubber insulative mats or dry wood platforms
over metal or concrete floors when working on any
electrical equipment. Do not wear damp clothing
(particularly wet shoes) or allow skin surfaces to be
damp when handling any electrical equipment.
Jewelry is a good conductor of electricity and
should be removed when working on the electrical
equipment.
Wear safety glasses whenever servicing the trans-
fer switch.
Do not smoke near the batteries.
Do not work on this equipment when mentally or
physically fatigued, or after consuming alcohol or
any drug.
WARNING
INCORRECT SERVICE OR REPLACEMENT OF PARTS CAN RESULT IN
DEATH, SEVERE PERSONAL INJURY, AND/OR EQUIPMENT DAMAGE. SER-
VICE PERSONNEL MUST BE TRAINED AND EXPERIENCED TO PERFORM
ELECTRICAL AND/OR MECHANICAL SERVICE.
