(5) Use shielded wires for inter-unit control wiring and ground the shield on both sides,
otherwise misoperation from noise may occur. Connect wiring as shown in Section
“ Wiring System Diagrams” on page 1-11-2.
(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. (60245 IEC57, 60245 IEC66)
WARNING
Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard may also occur.
Therefore, ensure that all wiring is tightly connected.
When connecting each power wire to the terminal, follow the instructions on “How to connect wiring to the terminal” and fasten the wire
securely with the terminal screw.
