1.3. Compliance with EMC directive
(1) Recommended EMI noise filters(refer to Table 2) should be installed to the input. These
can reduce the conducted and radiated noise.

(2) The main cables such as input to the EMI filter and output of the inverter and the signal
cables should be shielded, then cable length should be wired as short as possible. The main
input cable should be separated from the main output cable, and cables for control signal
also should be separated from main cables, not wiring parallel and not bundling, cross the
wires where necessary.
(3) Install EMI filter and inverter on the same metal back plate in an inverter panel. The metal
back plate or the cubicle must be grounded absolutely, by using short thick wires, separated
from the main cables.
(4) Please separate input cable to EMI filter from output cable as much as possible.
(5) Shielded cables should be grounded on the metal back plate in order to reduce the radiated
noise from the other cables. It is an effective measure that shielded cables are grounded
close to the inverter or/and operation panel or/and EMI filter(less than 10cm).
(6) Installation of the zero-phase and/or the ferrite core can also effectively reduce the radiated
noise further.(Input or/and output of inverter)
