Warning
Make sure the AC filter capacitor safety (PE) ground and connected correctly.
You can avoid injury and / or damage to the equipment.
✏
Note
:
The filter is an essential element of protection against electromagnetic disturbance Filters
prevent emitted interference acting on the power line and vice versa.

[Figure 8-4] Noise filter incorrect installation
The supply cable to the noise filter and outgoing cables from the noise filter must not run parallel to
each other (see illustration):
8.3. Method wiring
(1) Signal and communication cables is placing a high-voltage cable or power line over a
distance of 10cm, please not affected by the noise and magnetic field
(2) If possible use separate ducts for power cables and control lines.
(3) All cable should be the Shield cable.
(4) Minimizing the loops
[Figure 8-5] Avoiding loops in wiring designs
✏
Note: Wires that form a loop make an efficient antenna. Run feed and return wires together rather than
allowing a loop to form. Twisting the pair further reduces the antennae effects and can significantly reduce
EMI.
✏
Note
According to the NFPA79 approved by the United States, when the shielded wire is not used for
wiring between a servo amplifier and a servo motor, the wiring must be insulated from wiring of
other control or signal circuits. (Example: 100 mm or more for 20 A or less)
