NOTE
1. Where ground work (earth) is carried out, do not connect the ground return to the gas pipe, water line pipe, grounded circuit of the
telephone and lightning rod, or ground circuit of other product in which earth leakage breaker is incorporated. (Such action is pro-
hibited by statute, etc.)
Make sure the indoor and outdoor connection wires are detangled. (There might be effect to received outside noise.)
2. Use the standard power supply cables for Europe (such as H05RN-F or H07RN-F which conforms to CENELEC (HAR) rating spec-
ifications) or use the cables based on IEC standard. (245IEC57, 245IEC66)
3. Select the particular size of electrical wire for power supply cables in accordance with the standards of the given nation and region.
