The electric machine is designed for the following conditions:
Ambient temperature limits: -40°C...+65°C.
Maximum altitude 2000 m above sea level.
Maximum coolant liquid temperature at the inlet of the coolant circuit, see product data sheet.
Coolant liquid must be water- glycol mixture with maximum of 50 % glycol content. See
Chapter
Recommended coolants
.
If electric machine operation limits are exceeded, please contact Danfoss representative.
Condition monitoring during operation
Supervising the electric machine correctly during the operation ensures reliable operation and designed lifetime.
If you notice any deviations from the normal operation, for example elevated temperatures, noise or vibration, stop the
electric machine. Find the reason for the deviation and repair the electric machine. Refer to Chapter 9 Troubleshooting.
Maximum temperature of the bearings of the electric machine is 120°C.
Maximum temperature of the windings of the electric machine is 150°C.
Recommended lubricants
Do not mix different types of grease! Consult SKF for using other greases.
Greased for life bearings do not need relubrication during their lifetime. Grease relubricable
bearings (BHS option) need regular greasing. See Chapter Maintenance - Bearings and
lubrication for further information.
The recommended grease type for the machine bearings is SKF LGHP-2 or equivalent. LGHP-2 is
high performance, high temperature bearing grease. For further information, see
http://www.skf.com/
Each electric machine has its own greasing recommendations, see the sticker on the electric
machine or contact Danfoss.
Recommended coolants
Use correct personal protective equipment when you handle the coolant.
Ethylene glycol is a toxic compound. Avoid exposure to the coolant.
