Chapter 2. MOUNTING AND WIRING
•
Do not use unused terminals as relay terminals.
•
Use an overload prevention device for the power supply as needed.
•
For wiring to the power source, use a 0.75 mm
2
wire (30 cores, 0.18 mm dia.) in
keeping with JIS C3306.
•
Terminal screws for the external reset input (terminal numbers 9 and 10) are
not assembled. When using the external reset input, wire to the subbase using
the included terminal screws.
•
For the external reset input signal and flame voltage output signal, use IV wire
0.75 mm
2
in cross-sectional area. Wire length should be 10 m max.
•
Be sure to set up a separate external reset input for each device. The external
reset input of another device cannot be shared.
•
Although terminals with a ground mark are provided on the subbase, this de-
vice is not grounded.
