Power Supply Specifications
Use a power supply that meets the following specifications. (The power supply is sold separately.)
• Supply power from a DC power supply for which measures have been applied to prevent high voltages (e.g., a
safety extra-low-voltage circuit).
If UL certification is required for the overall system, use a UL Class II DC power supply.
• When using the FQ-D31, do not connect a switching regulator and AC Adapter (FQ-AC@) at the same time.
1 Loosen the two terminal screws using a Phillips
screwdriver.
2 Attach crimp terminals to the power lines.
Secure the positive and negative lines as indicated
using M3 screws.
Power supply tightening torque: 0.54 Nâ‹…m
3 In environments where there is excessive noise, at-
tach a ferrite core (ZCAT1730-0730 from TDK or the
equivalent) to the power supply cable.
1 Remove the cover from the power switch on the left side of
the Touch Finder.
2 Press the switch toward ON.
