NOTICE
OUTPUT CONTACTOR
Danfoss does not recommend using an output contactor on 525-690 V drives that are connected to an IT mains network.
Procedure
1. Strip a section of the outer cable insulation.
2. Establish mechanical fixation and electrical contact between the cable shield and ground by positioning the stripped wire under
the cable clamp.
3. Connect the ground wire to the nearest grounding terminal in accordance with the grounding instructions provided in 5.6
Connecting to Ground.
4. Connect the 3-phase AC input power wiring to terminals R, S, and T. See illustration 19.
5. Tighten the terminals in accordance with the specifications shown in
9.10 Fastener Torque Ratings.
6. When supplied from an isolated mains source (IT mains or floating delta) or TT/TN-S mains with a grounded leg (grounded delta),
ensure that parameter 14-50 RFI Filter is set to [0] Off to avoid damage to the DC link and to reduce ground capacity currents.
