2.4 Machine weight
The total weight of the machine can vary within the same
frame size (center height) depending on the output,
mounting arrangement and auxiliaries.
The following table shows estimated weights for machines
in their basic versions as a function of frame size and
length.

3. Installation and
commissioning
WARNING
Disconnect the power supply and lock any driven
equipment before working on the motor..
3.1 General
All rating plate values must be carefully checked to ensure
that the motor protection and connection will be properly
done.
Remove any transport locking, if employed. Turn the shaft
by hand to check that it rotates freely, if possible.
WARNING
Free rotation of the shaft is not applicable to motors
equipped with a brake
Motors equipped with roller bearings:
Running the motor with no radial force applied to the shaft
may damage the roller bearing.
Motors equipped with regreasing nipples:
When starting the motor for the first time, or after a long
period of storage, apply the specified quantity of grease.
For details, see section “6.2.2 Motors with regreasable
bearings”.
3.2 Insulation resistance check
Measure insulation resistance before commissioning and
when dampness is suspected in the winding.
WARNING
Disconnect and lock out before working on the
motor or the driven equipment.
The insulation resistance, corrected to 25 °C, must exceed
the reference value, i.e. 100 M
Ω
(measured at 500 or
1000 VDC). The insulation resistance value is halved for
each 20 °C rise in ambient temperature.
WARNING
The motor frame must be grounded and the wind-
ings should be discharged against the frame immedi-
ately after each measurement to avoid any risk of
electric shock.
If the reference resistance value is not attained, the wind-
ing is too damp and must be dried in an oven. The oven
temperature should be 90 °C for 12–16 hours, followed by
105 °C for 6–8 hours.
Windings which have become drenched in seawater
normally need to be rewound.
