(5)  Use shielded wires for inter-unit control wiring (c) 
and ground the shield on both sides, otherwise 
misoperation from noise may occur. (Fig. 4-4)
Connect wiring as shown in Section 4-3. “Wiring 
System Diagram.”
Fig. 4-4
(6)  Use the standard power supply cables for Europe 
(such as H05RN-F or H07RN-F which conform to 
CENELEC (HAR) rating specifications) or use the 
cables based on IEC standard. (245 IEC57, 245 IEC66)

(4)  If branching the inter-unit control wiring, the number of branch points should be 16 or fewer. 
(Branches less than 1 m are not included in the total branch number.) (Fig. 4-3)

(3)  Do not install inter-unit control wiring such as star branch wiring. Star branch wiring causes mis-address setting.
(2)  Do not install the inter-unit control wiring in a way that forms a loop. (Fig. 4-1)
WARNING
Loose wiring may cause the terminal to overheat or result 
in unit malfunction. A fire hazard may also exist. Therefore, 
ensure that all wiring is tightly connected.
When connecting each power wire to the terminal, follow the 
instructions in “How to connect wiring to the terminal” and 
fasten the wire securely with the fixing screw of the terminal 
plate.
