Storage
If the generator will not be installed in its operating location upon
being received, store the generator according to the following
procedures.
Recommended storage area temperature is between 0 ° F (-18 ° C)
and 120 ° F (49 ° C) with relative humidity at less than 60%. The
recommended temperature may be lower if the generator is designed
for lower temperatures; consult the nameplate.
Protect the shaft from corrosion by applying an anti-corrosion agent.
Cover the generator with a durable cover.
Prepare generators that cannot be stored in a temperature and
humidity controlled area as follows:
1. Install desiccant bags in the exciter cover and inside each end
bell.
2. Vacuum seal the generator in a covering of plastic or other
material designed for that purpose.
3. Adequately tag the generator to ensure that preservative greases
and desiccant bags are removed before the unit is placed in
operation.
4. If space heaters are supplied, energize them to keep condensation
from the windings.
5. Lubricate the sleeve bearings and the shaft as describe in the
following paragraphs.
Generator coupled to prime mover - generator and
prime mover may be rotated as single unit.
For storage longer than 2 months, rotate the shaft a minimum of 10
revolutions every 60 days. Activate automatic lubrication system (if
included with generator) prior to turning the shaft. Activate manual
prelube pump (if included with generator) prior to rotating the shaft.
If the generator has no prelube system, remove the access glass or top
vent and pour oil into bearing before rotating the shaft.
Generator coupled to prime mover - prime mover
manufacturer requires that the prime mover NOT be
rotated at periodic intervals.
1. Separate the coupling from the prime mover and the generator.
Rotate the generator separately a minimum of 10 revolutions
every 60 days. Activate automatic lubrication system (if included
with generator) prior to turning the shaft. Activate manual
prelube pump (if included with generator) prior to rotating the
shaft. If the generator does not have a prelube system, remove
the access glass or top vent and pour oil into bearing prior to
rotating the shaft.
2. If it is not possible to rotate the generator separately, flush the
bearings with an anti-rust preservative using one of the bearing
preservation procedures.
WARNING: When removing the
oil or external lubrication system from
bearings for long term storage oil must
be added to the bearing, or the external
lubrication system must be reconnected
prior to operation. Please refer to the
generator dimensional drawing for
amount of oil required or location for oil
input and drain port locations.
