Table 5.1 Specifications on Required Components for (1) to (4) Functions
NOTE:
1. Make the wires CN3 as short as possible. Do not install the wires with the 220V power line. Install them
more than 12 in. (30cm) away from each other. (Intersecting them is acceptable.)
If the wires are installed along the power line, comply with the following points to prevent noise.
a. Pass either of the low voltage wire and 220V power line through a metal conduit tube and ground one
end.
b. Use a shielded wire for a low voltage wire and ground one end.
The maximum wiring length is 230 ft. (70m).
2. When using this function, it is recommended that safety devices such as an electric leakage breaker or
smoke detector, etc., be used because this is an unattended function.
