• Connecting mains filter for power source line
Install a mains filter on the input side of the DC power supply in order to prevent the
noise generated within the driver from propagating outside via the DC power source
line. For mains filters, use 10ESK1 (Tyco Electronics CORCOM), ZAG2210-11S
(TDK Corporation), or an equivalent.
Install the mains filter as close to the AC input terminal of DC power source as
possible, and use cable clamps and other means to secure the input and output cables
(AWG18: 0.75 mm
2
or more) firmly to the surface of the enclosure. Connect the
ground terminal of the mains filter to the grounding point, using as thick and short a
wire as possible.
Do not place the AC input cable (AWG18: 0.75 mm
2
or more) parallel with the
mains filter output cable (AWG18: 0.75 mm
2
or more). Parallel placement will
reduce mains filter effectiveness if the enclosure’s internal noise is directly coupled
to the power supply cable by means of stray capacitance.

How to ground
The cable used to ground the driver,
actuator and mains filter must be as thick
and short to the grounding point as
possible so that no potential difference is
generated. Choose a large, thick and
uniformly conductive surface for the
grounding point.

• Wiring the power cable and signal cable
Use a shielded cable of AWG18 (0.75 mm
2
) or more in diameter for the driver
power cable. Use a shielded cable of AWG28 (0.08 mm
2
) or more in diameter for the
driver signal cable, and keep it as short as possible. Contact the nearest sales office
for a shielded cable (sold separately).
To ground a shielded cable, use a metal clamp or
similar device that will maintain contact with the
entire circumference of the shielded cable. Attach a
cable clamp as close to the end of the cable as
possible, and connect it to an appropriate
grounding point as shown in the figure.
