• On some models, terminals are not used and are left free. Do not wire
these terminals.
• Separate input leads and power lines in order to protect the controller
and its lines from external noise.
• We recommend using solderless terminals when wiring the controller.
• Tighten the terminal screws using a torque no greater than 0.78 N¡m
(8kgf¡cm).
• Use the following type of solderless terminals for M3.5 screws.
In the following wiring diagrams, the left side of the terminal Nos. indi-
cates the inside of the controller.
• Input power to terminals Nos. 9 and 10. Power specifications are as fol-
lows:
100 to 240 VAC, 50/60 Hz, approx. 15 VA
or
24 VAC, 50/60 Hz, approx. 12 VA
