• Competent, qualified personnel should install,

operate and service 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

standing in water, while barefoot, or while hands or

feet are wet. DANGEROUS ELECTRICAL SHOCK

MAY RESULT.

• Jewelry conducts electricity and wearing it may

cause dangerous electrical shock. Remove all jew-

elry (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 nonconduct-

ing 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 cir-

cuit must be disabled before working on or around

the generator or transfer switch. For that purpose,

a SAFETY DISCONNECT is provided inside the

transfer switch. Always set that switch to its OFF

position before working on the equipment. Then

place a "DO NOT OPERATE" tag on the transfer

switch and on the generator. Remove the Negative

(Neg) or (-) battery cable.
