Motor Cable Requirements for CE & C-Tick Compliance
The requirements in this section apply for CE or C-Tick compliance.
Minimum Requirement (CE & C-Tick)
The motor cable must be a symmetrical three conductor cable with a concentric PE
conductor or a four conductor cable with a concentric shield, however, a symmetrical
constructed PE conductor is always recommended. The following figure shows the
minimum requirement for the motor cable screen (for example, MCMK, NK Cables).
* Input filters designed for ACH550 cannot be used in an isolated, or high impedance earthed
industrial distribution network.
