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.
