The following description applies for an electromagnetic clutch secured to a shaft. To absorb the magnetic field of the electromagnetic clutch, the front bearing flange has a snug fit Ø 148 h8 (see Fig. 8). To connect the magnetic field, loosen the 4 cheese head screws M8 on the bearing flange (see Fig. 8). Slide the magnetic field to a snug fit and re-attach using the four cheese head screws M8 (Fig. 9). Screw torque = 37 Nm. Further assembly of the electromagnetic clutch according to the clutch manufacturer.

Connection 3 is provided for safety devices and is not lockable. After activating the spindle, generally fit the spindle protection cap again and tighten with 14-16 Nm. This serves as a second sealing feature during operation. 4.10 Suction pipe filter For systems with long pipes and higher degree of contamination, a filter on the suction-side is recommended. The filter has to be be renewed depending on the degree of contamination (reduced pressure loss). © Danfoss | Climate Solutions | 2023.07 12 | AQ450736920607en-000201... -
