• 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.
