Installation
Receiving Inspection
Before accepting a shipment, examine the packaging for any sign of
damage that might have occurred during transit. Report any damage to
the transportation company and Kato Engineering.
Unpacking and Moving
If the generator is received during cold weather, reduce condensation
on cold surfaces and failure due to wet windings by allowing the
generator to reach room temperature before removing the protective
packing.
Unpack the generator carefully to avoid scratching painted surfaces.
Do not remove the protecting lubricant from the shaft end or drive
plates. Inspect for loosely mounted components and the presence
of moisture. Inspect to make certain foreign material, such as
crating nails, loose bolts or packing material, which may have
fallen into the machine during unpacking, is removed. If damage is
noticed, determine the extent of damage and immediately notify the
transportation company claims office and Kato Engineering. Be sure to
give complete and accurate details when reporting damage.
Move the generator by attaching an overhead hoist to the eyebolts
installed on the generator frame or by lifting the generator from
underneath the skid with a forklift.
Single-bearing generators are shipped with the exciter rotor assembly
removed from the shaft and a support mounted across the drive discs to
support the rotor.
Location
Install the generator in an area so it complies with all local and
industrial regulations. Locate it in a clean, dry, well-vented area or
area that is suitable for the generator enclosure. Make sure it is easily
accessible for inspection and maintenance.
Check winding insulation resistance before placing the generator in
operation (see the maintenance section).
Protect generators operating intermittently in very damp locations with
space heaters. Slowly warm generators placed in operation after being
subjected to very low temperatures to prevent excessive condensation.
Base Design
The type of base to be used will depend upon the nature of the
installation site. However, the generator base must be rigid, level, and
free from vibration. Mounting holes must be larger than the fasteners to
allow for alignment.
WARNING: Electric shocks can
occur from faulty ground connections on
portable electrical equipment and failure
to ground stationary equipment which
may result in death or injury. Be alert
at all times when installing, operating
and maintaining the generator. Avoid
contact with the uninsulated metal parts
of the generator. Test all portable devices
frequently to prove that a solid electrical
circuit exits from the metal frame though
the grounding conductor, in the electrical
cord, to the grounding contact in the
attachment plug. Do not use electrical
equipment with frayed, burned or
damaged cords.
Always take extreme care when moving
the generator. Be careful to not strike
objects or personnel.
WARNING: Apply lifting force to
structural points specifically provided for
lifting. Do not use the enclosure lifting
holes to lift the whole unit. Use lifting
means adequate for the weight. Observe
lifting notices attached to the generator.
Failure to observe these instructions
can result in injury and damage to the
generator.
NOTE: Do not attempt to transport
a single-bearing generator without
maintaining proper rotor support and
with the exciter rotor assembly removed.
Failure to observe this warning can result
in equipment damage.
NOTE: Blocking or restriction of normal
air flow into or out of the generator may
cause damage to the electrical windings.
