NOTE
⚫
Whenever possible, use the Cables specified by Trio.
⚫
Securely tighten cable connector screws and lock mechanisms to prevent mechanical
failure during operation.
⚫
Ensure that power lines (e.g. Main Circuit Cable) and low-current lines (e.g. I/O Signal
Cables or Encoder Cables) are separated by at least 30 cm. Do not bundle power lines
and low-current lines through the same duct.
IMPORTANT
⚫
Use a Type C MCB to protect the main circuit.
The Drive connects directly to a commercial power supply; it is not isolated through a
transformer or other device. Always use a Type C MCB to protect the Servo System
from accidents involving different power system voltages or other accidents.
⚫
Install an earth leakage breaker.
To configure a safer system, install a ground fault detector against overloads and short-
circuiting, or install a ground fault detector combined with a Type C MCB.

Countermeasures against Noise
IMPORTANT
⚫
Refer to DX4 Servo drive Product Manual, Noise Filters and Grounding sections before
continuing with this manual
3.1.3
Recommended EMC Filters
To comply with the limits based on IEC/EN 61800-3 second environment (C2) the Drive and Motor must be
installed with an EMC/RFI filter. For the whole system, 4 units of DX4 drives, recommended filters are:
RX
–400 … 700
-SR
EMC C2 (three phase supply)
EMC C2 (single phase supply)
4 units of DX4 drives (100 W to 400
W depending on model)
Schaffner FN3270H-10-44
Schaffner FN2090-10-06
These filters have been tested with cable lengths of 3m and 20m.
