These safety warnings cannot eliminate the hazards that they 

indicate. Common sense and strict compliance with the special 

instructions while performing the service are essential to prevent-

ing accidents.
Four commonly used safety symbols accompany the DANGER, 

WARNING and CAUTION blocks. The type of information each 

indicates follows:

 

 

This symbol points out important safety infor-

mation that, if not followed, could endanger 

personal safety and/or property.





This symbol points out potential explosion 

hazard.



T

his symbol points out potential fire hazard.

   



T

his symbol points out potential electrical 

shock hazard.

GENERAL HAZARDS

•  Any AC generator that is used for backup power if a NORMAL 

(UTILITY) power source failure occurs, must be isolated from 

the NORMAL (UTILITY) power source by means of an approved 

transfer switch. Failure to properly isolate the NORMAL and 

STANDBY power sources from each other may result in injury 

or death to electric utility workers, due to backfeed of electrical 

energy.

• Improper or unauthorized installation, operation, service or 

repair of the equipment is extremely dangerous and may result 

in death, serious personal injury, or damage to equipment and/

or personal property.

• Extremely high and dangerous power voltages are present 

inside an installed transfer switch. Any contact with high voltage 

terminals, contacts or wires will result in extremely hazardous, 

and possibly LETHAL, electric shock. DO NOT WORK ON THE 

TRANSFER SWITCH UNTIL ALL POWER VOLTAGE SUPPLIES 

TO THE SWITCH HAVE BEEN POSITIVELY TURNED OFF.

•  Competent, qualified personnel should install, operate and ser-

vice this equipment. Adhere strictly to local, state and national 

electrical and building codes. When using this equipment, 

comply with regulations the National Electrical Code (NEC), 

CSA Standard; C22.1 Canadian Electric Code and Occupational 

Safety and Health Administration (OSHA) have established.

•  Never handle any kind of electrical device while stand-

ing in water, while barefoot, or while hands or feet are wet. 

DANGEROUS ELECTRICAL SHOCK MAY RESULT.

• Remove all jewelry (such as rings, watches, bracelets, etc.) 

before working on this equipment.

•  If work must be done on this equipment while standing on metal 

or concrete, place insulative mats over a dry wood platform. 

Work on this equipment only while standing on such insulative 

mats.

• Never work on this equipment while physically or mentally 

fatigued.

•  Keep the transfer switch enclosure door closed and bolted at all 

times. Only qualified personnel should be permitted access to 

the switch interior.

•  In case of an accident caused by electric shock, immediately 

shut down the source of electrical power. If this is not possible, 

attempt to free the victim from the live conductor but AVOID 

DIRECT CONTACT WITH THE VICTIM. Use a nonconducting 

implement, such as a dry rope or board, to free the victim from 

the live conductor. If the victim is unconscious, apply first aid 

and get immediate medical help.

•  When an automatic transfer switch is installed for a standby 

generator set, the generator engine may crank and start at 

any time without warning. To avoid possible injury that might 

be caused by such sudden start-ups, the system’s automatic 

start circuit must be disabled before working on or around the 

generator or transfer switch. Then place a “DO NOT OPERATE” 

tag on the transfer switch and on the generator. Remove the 

Negative (Neg) or (–) battery cable.

For authorized service, 

reference the dealer locator

number found inside the

generator owner’s manual.
