■ Precautions for wiring the type2 light controller
(1) Power condition
Connect the power supply that meets the rated voltage, frequency, distortion rate and
other ratings of the power module. (For the power module rating, refer to "Appendix A
Power Module Specification.")
[Example] Line voltage: 85 - 264 VAC, 50/60 Hz (PS693)
Required power: 120VA or less (PS693)
Allowable short interruption: 10 ms
If the power condition is unstable, insert a constant-voltage transformer to
stabilize the voltage.
(2) Insert a shield transformer or noise filter (see the figure below). It is also
recommended to install two turns of a ferrite core close to the power module.

(3) Use a 1.25-mm or thicker twisted pair cable for the power cable.
Separate the power cable and ground wire from the IO lines.
(4) Power supplies to the TC-net I/O and intelligent I/O nodes connected to the type2 light
controller need not be integrated into the same system as the basic unit, but should
be turned on prior to or simultaneously with the power supply of the basic unit.
(5) When the power is supplied from the CVCF or UPS, check that the crest value of
voltage waveform is greater than 130 V in the 100 VAC line, or 260 V in the 200 VAC
line.
