3.2.1.5
Installation Recommendations for EMC Compliance
For compliance with EN 61800-3 or other EMC standards, motor cables, line cables and control or communications
cables must be shielded with each shield/screen clamped to the drive chassis. This clamp is typically located at the
conduit mounting plate.
The EMC requirements apply to the final installation in its entirety, not to the individual components used. Because
every installation is different, the recommended installation should follow these guidelines as a minimum. Additional
equipment (such as ferrite core absorbers on power conductors) or alternative practices may be required to meet
conformance in some installations.
Motor cable should be low
capacitance (core/core <75pF/m,
core/shield <150pF/m). Filtered
drives can meet the class A limits
of EN 55011 and EN 61800-3
Category 2 with this type of motor
cable up to 10 meters.
NOTE: Refer to Appendix A for
recommended cable lengths. Any
external line filter should have its
chassis connected to the drive
chassis by mounting hardware
or with the shortest possible wire
or braid.

NEMA 4X (IP65) Input Terminal Block
For NEMA 4X (IP65) models with integrated EMC filter and/or integrated line disconnect, the input terminal block is
located on the right-hand side of the SMV inverter in the NEMA 4 X (IP65) enclosure. The single and three phase models
are illustrated herein. Refer to paragraph 3.2.3 Control Terminals for pin out information.

WARNING
Power remains present for up to 3 minutes on power input terminals (L1, L2 and L3) and output
terminals (U, V and W) even when the disconnect switch is in the OFF position. Remove input power
ahead of the drive and wait 3 minutes before removing the terminal cover.
