3. INSTALLATION
3.1 TRANSPORT AND STORAGE
3.1.1 Transport
During the transport the intermittent shocks level applied to
the machines must remains below 30 m/s
2
Machines equipped with anti friction bearing must have
their rotor locked during the transport to avoid "false
brineling" problem
Machine temperature must remains within the range -20°C
to +70°C. Stay down to -40°C during few hours is admitted.
The machine must be protected against bad weather
conditions and condensation.
3.1.2 Storage warehouse
The machine must be stored in clean and dry premises
which are not subject to abrupt changes in temperature or
to high humidity (75% maximum)
CAUTION:
THE HEATING RESISTOR MUST BE CONTINUOUSLY
SWITCHED ON
Storage at an ambient temperature of +5 to +45° C is
recommended.
The machine must not be subject to vibrations higher than
1mm/s rms
3.1.3 Maritime packing
The synchronous machine is hermetically sealed then
packed in a wooden crate.
In any case the generator must be store in a warehouse
(refer to chapter 3.1.2)
This packing provides access to the dessicant for periodic
change (every 18 months)
CAUTION :
BREAKING THE HERMETIC PROTECTIVE FILM
DISCHARGES LEROY SOMER OF ITS LONG STORAGE
GUARANTEE
3.1.4 Unpacking and installation
DANGER :
THE DEDICATED LIFTING HOOKS MUST BE USED TO
LIFT THE MACHINE WITH SLINGS (ONE HOOK AT
EACH CORNER OF THE MACHINE)
Rotors of machines with Sleeve bearings and single-
bearing machines, are blocked during transportation so as
to avoid any movement. Withdraw the retaining bars. The
retaining bar is screwed to the end of the shaft and to the
front support.
CAUTION :
TRANSPORT LOCKING DEVICES PAINTED RED OR
WITH RED STICKER MUST BE REMOVED.
The end of the shaft is protected from corrosion. Clean it
before coupling.
The heating resistor must be switched on at all times.
Before starting the machine up again, it will be necessary
to carry out a start-up inspection.
3.1.5 Storage measures of antifriction bearings
This chapter must be taken in consideration if a machine is
stopped more than 6 months.
After 6 months of stop; grease by injecting two time the
grease volume used for a standard maintenance.
Then, each 3 months turn the machine shaft line of few
turns while injecting a standard grease volume
3.1.6 Not applicable
3.1.7 Not applicable
3.1.8 Storage measures of open drip proof machines
For an open machine, it is recommended that the air inlet
and outlet be closed.
