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.
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 trans-
fer switch and on the generator.
