3. INSTALLATION
3.1 TRANSPORT AND STORAGE
3.1.1 Transportation
During transport the level of intermittent shocks suffered by
the machines must remain below 30 m/s
2
.
Machines equipped with roller bearing(s) must have their
rotor locked during the transport to avoid any "false
brineling" problem.
The temperature of the machine must remain between
-20°C and +70°C. However, it is possible to go down to
-40°C if not for more than a few hours.
The machine must be protected against the weather and
condensation.
3.1.2 Warehouse Storage
This chapter applies to machinery not protected by a
sealed package (for machinery with a sealed package, see
Chapter 3.1.3).
The machinery must be stored in a clean and dry place
which is not subject to sudden temperature changes or
high humidity (75 % maximum).
Storage at an ambient temperature of +5 to +45°C is
recommended.
The machine must not be subject to vibrations greater than
1mm/s rms.
CAUTION:
THE RESISTANCE HEATER MUST BE CONTINUOUSLY
SWITCHED ON.
3.1.3 Storage in maritime packaging
The synchronous machine was hermetically sealed in the
factory and then packed in a wooden box (SEI class 4c
standard).
Storage in a hermetically sealed package and wooden box
made by Leroy-Somer is guaranteed 2 years. In this case,
there is no special weatherproof precaution to be taken.
In this case, the precautionary measures in Chapter 3.1.5;
3.1.6; 3.1.7; 3.1.8 do not apply.
The machine must not be subject to vibrations greater than
1mm/s rms.
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 resistance heater 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 Roller bearing storage measures
This chapter must be followed if a machine remains
stationary for more than 6 months.
After 6 months of stop; lubricate by injecting two times the
grease volume used for a standard maintenance.
Then, every 3 months turn the machine shaft line by a few
turns while injecting a standard grease volume.
3.1.6 Uncovered machinery storage measures
For an uncovered machine, it is recommended to close the
air inlet and outlet.
