A4.4. Noise Considerations

Isolation from Power and Motor-circuit Cables
Lay any power or motor-circuit cable at least 20 cm away from the DTSXL system and
all signal cables connected to the DTSXL system. Should this be impossible, run the
power or motor-circuit cables all the way through a metal conduit that is grounding (100
Ω or less).


Antinoise Measures for Power Supply Module and Circuit
- Twist the power supply wires and minimize the wiring length.
- The power supply modules of the DTSXL System incorporate a noise filter and
hence have ample immunity to the level of noise likely to occur in generic
applications. However, for use in an environment of high noise levels, it is
recommended to interpose a noise filter or noise-cut transformer in the power
supply wiring.
