• Check the direction of rotation and operation during idle running. In case of
unidirectional external fans (axial fans) observe the sign for the direction of
rotation on the motor. If the direction of rotation needs to be changed,
invert the two power lines and the fan.
• If the motor was stored and an additional quantity of grease was applied in
the anti-friction bearings, the motor must be run with no load for at least
0.5 h to ensure an adequate distribution of the grease and to avoid the
overheating of the anti-friction bearings.
• Make sure that the operating current matches the specified current values
on the rating plate.
The protective equipment required as per EN 60079-14 is to be set
according to the motor rating values specified on the rating plate. The
specified current value on the rating plate must not be exceeded in
continuous duty conditions.
Please note!
Run the motor with load for at least 1 hour and check that
there is no unusual noise or heating exceeding the specified
temperature class values.
Relubricate motors with regreasing equipment with the specified amount of
grease during start-up.
Vibration severity values of V
eff
≤ 3.5 mm/s (P
N
≤15 kW) or 4.5 mm/s
(
P
N
> 15 kW) in coupled operating mode are not allowed. In case of
deviations from normal operating conditions – e.g. higher temperatures or
greater noise and vibrations – find the cause and, if necessary,
contact Producent.
Please note!
The protective equipment must always be kept in service also
during trial runs. In case of doubt switch off the machine.
