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.
