• 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 working 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 MAN-
UAL position before working on the equipment.
Then place a "DO NOT OPERATE" tag on the
transfer switch and on the generator.
