C-2 CE Conformity
General Instructions for an EMC Compliant Installation
Shielded Enclosure
Typical NEMA or IEC metal enclosures are adequate.
The ground connection of the shielded enclosure must be solidly connected to
the PE terminal of the drive. Good conductivity must be assured – grounding
must provide a low impedance path for high frequency signals.
All wiring, except input power leads, must use shielded cable.
Input power, output power and control wiring inside the enclosure must be
physically separated.
Input power, output power and control wiring outside the enclosure must use
separate shielded cables, or separate conduit.
Wires do not touch the heatsink.
