• 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 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 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. For that
purpose, a SAFETY DISCONNECT is provided
inside the transfer switch. Always set that switch
to its MANUAL 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.
