SAFETY
PLEASE REMEMBER SAFETY FIRST. If you are not sure of
the instructions or procedures contained herein, seek
qualified help before continuing.
This service manual emphasizes the safety precautions
necessary during the installation, operation, and
maintenance of your MagnaPLUS
®
generator. Each section of
this manual has caution and warning messages. These
messages are for your safety, and the safety of the equipment
involved. If any of these cautions or warnings are not
readily understood, seek clarification from qualified
personnel before proceeding.
Before any service work is done, disconnect all power
sources and lock out all controls to prevent an unexpected
start up of the generator set driver. Proper grounding
(earthing) of the generator frame and distribution system in
compliance with local and national electrical codes and
specific site requirements must be provided. These safety
precautions are necessary to prevent potential serious
personal injury, or even death.
The hazards associated with lifting or moving your
MagnaPLUS
®
generator are pointed out in the installation and
maintenance sections. Incorrect lifting or moving can result in
personal injury or damage to the unit.
Prior to start up of the unit ensure that all generator leads are
properly connected to the generator link board located inside
the connection box. Always assume that there will be voltage
present at the generator terminals whenever the generator's
shaft is rotating, and proceed accordingly. Residual voltage is
present at the generator terminals and at the automatic
voltage regulator panel connections even with the regulator
fuse removed. Caution must be exercised, or serious injury or
death can result.
This manual is not intended to be a substitute for properly
trained personnel. Installation and repairs should only be
attempted by qualified, trained people. The cautions and
warnings point out known conditions and situations that are
potentially hazardous. Each installation may well create its
own set of hazards.
When in doubt, ask. Questions are much easier to handle
than mistakes caused by a misunderstanding of the
information presented in this manual.
RECEIVING AND STORAGE
RECEIVING AND STORAGE
Upon receipt of the generator, it is recommended that it be
carefully examined for possible shipping damage. The
generator was given to the freight carrier in good condition;
thus, the carrier is responsible for the product from the
factory dock to the destination. Any damage should be noted
on the freight bill before accepting the shipment. Any claims
for damage must be promptly filed with the delivering carrier.
UNPACKING AND HANDLING
Carefully read all instruction tags shipped with the unit. When
lifting, attach an overhead crane to the lifting lug(s) on the
generator frame. Apply lifting forces in a vertical direction.
When transporting single bearing generators, the generator’s
rotor must be adequately supported to prevent damage.
THE LIFTING LUG(S) ON THE GENERATOR ARE
DESIGNED TO SUPPORT THE GENERATOR ONLY.
DO NOT LIFT A COMPLETE GENERATOR AND
DRIVER ASSEMBLY BY MEANS OF LIFTING LUG(S)
ON THE GENERATOR. PERSONAL INJURY OR
EQUIPMENT DAMAGE MAY RESULT.
STORAGE
In the event that the generator is not immediately installed on
its prime mover, it is recommended that the unit be stored
indoors in a clean, dry area which is not subject to rapid
changes in temperature and humidity. If the generator is
stored for a long period of time, the generator should be
tested, cleaned and dried as required before being put into
service. See the maintenance section of this manual for
further information. If the unit has been stored in an area
where it has been subject to vibration, it is recommended that
the bearing(s) be inspected and replaced as necessary.
