• Because jewelry conducts electricity, wearing it

may cause dangerous electrical shock.  Remove all

jewelry (such as rings, watches, bracelets, etc.)

before working on this equipment.

• If you must work 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 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.  Always set the

Auto-Off-Manual 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.
