These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the service are essential to preventing
accidents.
Four commonly used safety symbols accompany the DANGER,
WARNING and CAUTION blocks. The type of information each indi-
cates follows:
This symbol points out important safety infor-
mation that, if not followed, could endanger
personal safety and/or property.
This symbol points out potential explosion
hazard.
T
his symbol points out potential fire hazard.
T
his symbol points out potential electrical
shock hazard.
GENERAL HAZARDS
• Any AC generator that is used for backup power if a NORMAL
(UTILITY) power source failure occurs, must be isolated from
the NORMAL (UTILITY) power source by means of an approved
transfer switch. Failure to properly isolate the NORMAL and
STANDBY power sources from each other may result in injury
or death to electric utility workers, due to backfeed of electrical
energy.
• Improper or unauthorized installation, operation, service or repair
of the equipment is extremely dangerous and may result in death,
serious personal injury, or damage to equipment and/or personal
property.
• Extremely high and dangerous power voltages are present
inside an installed transfer switch. Any contact with high voltage
terminals, contacts or wires will result in extremely hazardous,
and possibly LETHAL, electric shock. DO NOT WORK ON THE
TRANSFER SWITCH UNTIL ALL POWER VOLTAGE SUPPLIES
TO THE SWITCH HAVE BEEN POSITIVELY TURNED OFF.
• Competent, qualified personnel should install, operate and service
this equipment. Adhere strictly to local, state and national electri-
cal and building codes. When using this equipment, comply with
regulations the National Electrical Code (NEC), CSA Standard;
C22.1 Canadian Electric Code and Occupational Safety and
Health Administration (OSHA) have established.
• 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.
• 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 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 gen-
erator 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.
For authorized service,
reference the dealer locator
number found inside the
generator owner’s manual.
