GENERAL SAFETY INSTRUCTIONS
Before installing, using, or servicing this product, carefully read and fully understand the instructions including all warnings, cautions,
and safety notice statements. To reduce risk of personal injury, death and/or property damage, follow all instructions for proper generator
installation, operation and maintenance.
Although you should read and follow these instructions, they are not intended as a complete list of all details for installations, operation, and
maintenance. If you have any questions concerning any of the procedures, or if you have a safety concern not covered by the instructions, STOP, and
contact the generator manufacturer.
DEFINITION: The word Generator, as used in this publication, includes
only the products of Regal Beloit America, Inc., and does not include the
prime mover or any of the prime mover related systems or accessories.
ELECTRICAL HAZARD
• Failure to connect the voltage regulator in accordance with the
manufacturer’s documentation could result in serious personal injury,
death, and/or property damage.
ELECTRICAL SHOCK HAZARD
• Failure to follow these instructions could result in serious personal
injury, death, and/or property damage.
• Installation and repair of electrical generators and voltage regulators
should be attempted by qualified personnel only. Electrical connections
shall be made by a qualified electrician in accordance with all
local, national, international and/or other applicable codes, rules or
regulations and sound practices.
• Do not touch electrically live parts. Disconnect, lock out and tag prime
mover and input power supplies before installing or servicing voltage
regulator. Use a voltmeter to verify that power is off before contacting
conductors.
• Do not open terminal box or touch unprotected terminals while
the generator shaft is rotating. Shaft rotation produces voltage in
generators even when no excitation is applied. Residual voltage is
present at the generator leads and regulator connections even when
the regulator fuse is removed.
• Ground (earth) the regulator in accordance with local, national,
international and/or other applicable codes, rules or regulations.
EXPLOSION HAZARD
• Beware of arcing when connecting test leads. Arcing could spark an
explosion if exposed to battery gases, fuel vapors or other hazardous
atmospheres. Failure to follow these instructions could result in
serious personal injury, death and/or property damage.
ROTATING PARTS HAZARD
• Keep extremities, hair, jewelry and clothing away from moving parts.
Failure to follow these instructions could result in serious personal
injury, death and/or property damage.
OVERSPEED HAZARD
• Do not exceed the rated speed of the generator. Excessive centrifugal
forces could damage the rotating fields and cause parts to be expelled
at a high rate of speed. Failure to follow these instructions could result
in serious personal injury, death and/or property damage.
DO NOT DISASSEMBLE
• Only qualified personnel who know local, national, international and/or
other applicable codes, rules or regulations and sound practices should
install or repair electric generators and voltage regulators. Failure to
follow these instructions could result in serious personal injury, death
and/or property damage.
MAGNETIC FIELD HAZARD
• Permanent magnet generator (PMG) rotors, when removed from the
stator, expose surrounding personnel and equipment to powerful
magnetic fields which could cause serious health hazards to persons
with pacemakers, hearing aids, or other implanted electronic medical
devices and may impact other electronic devices such as mobile
phones, credit cards, etc.
