Chapter 3 Installation and Wiring
■ Power supply wiring for base unit BUM7B
(1) Power supply condition
(2) Mount an electrostatic shielded transformer or a noise filter (see the figure below). In
(3) Use a twisted-pair cable of 1.25mm
(4) The power of the main and remote base units should be supplied from the same source.
(5) If the power is fed from the CVCF or UPS, observe power supply waveforms to make

Connect the power supply that meets the specifications including voltage and frequency
ratings and distortion rate (for the power supply ratings of base unit BUM7B, refer to
"Appendix A Power Supply Specifications").
[Example] Power-supply voltage: 100-120Vac, 200-240Vac, 50/60Hz
Rated current: 1.5A or less (100-120Vac)
Allowable momentary interruption: 10ms
If the power supply is unstable, install a constant voltage transformer to stabilize the
voltage.
addition, using a 2-turn ferrite core near the power module is recommended.
power supply and common lines from the I/O wires wherever possible.
Configure the system to supply the power to these units simultaneously (or in the order
of the remote base unit and main base unit).
The TC-net I/O node power supply connected to the type1 light controller does not need
to be the same system as for the main base unit, but must be turned on prior to or
simultaneously with the main base unit.
sure the peak voltage is 130V or more for the 100Vac system and 260V or more for the
200Vac system. The distortion factor of the power supply must be 10% or less.
