1
* Pulse signal: normally OFF (open), ON (closed) when shorted
2
* When affected by interference by induction, select shielded CVV cable (CVV-S cable). This is
because copper shielding tape is wrapped around CVV cable and induction interference from ad-
jacent power cables is alleviated and normal communication is maintained. In addition, when the
wiring is outdoors, select weather resistance cable.

* Use cable in accordance with local regulations and rules for cable.
