•
Size the wiring according to the input current of the drive. For maximum wire sizes, see chapter 9.1 Electrical Data.
•
Comply with local and national electrical codes for cable sizes.
Procedure
1. Strip a section of the outer cable insulation.
2. Establish mechanical xation 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 chapter 5.6 Connecting to Ground.
4. Connect the 3-phase AC input power wiring to terminals R, S, and T (see Illustration 5.4).
5. When supplied from an isolated mains source (IT mains or oating delta) or TT/TN-S mains with a grounded leg
(grounded delta), ensure that parameter 14-50 RFI Filter is set to [0] O to avoid damage to the DC link and to
reduce ground capacity currents.
6. Tighten the terminals in accordance with the information provided in chapter 9.10.1 Fastener Torque Ratings.
