lubricating device
connection
• One or two terminal boxes for power cables
• Auxiliary terminal boxes (optional)
• Sensor signal:
– Directly on the sensor (water-cooled)
– Auxiliary terminal box on external fan cowl
(forced ventilation)
Installation altitude acc. to EN/IEC 60034-1 For an installation altitude > 1,000 m above sea
level
• The supplementary conditions specified in the
converter documentation must be observed
• The derating factor as per Chapter "Air
Cooling" must be observed.
Ambient Temperature during Operation -20°C to +40°C
2)
optional to +60°C
Storage temperature -20°C to +70°C
Positive direction of rotation Clockwise when looking at the drive end
1) The specified values only refer to the motor. These values can be increased at the motor due to
the overall vibration characteristics of the complete system after the drive has been mounted.
2) At temperatures below 0°C, anti-freeze is required for water-cooled motors.
