(3) Use shielded wires for inter-unit control wiring (c) and ground the shield on both sides, otherwise
misoperation from noise my occur. (Fig. 1-2)
Connect wiring as shown in Wiring System Diagram.”

(4) 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)
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 on “How to connect wiring to the terminal”
and fasten the wire securely with the fixing screw of the terminal plate.

How to connect wiring to the terminal
For stranded wiring
(1) Cut the wire end with cutting pliers, then strip the
insulation to expose the stranded wiring about
10 mm and tightly twist the wire ends. (Fig. 1-3)
(2) Using a Phillips head screwdriver, remove the
terminal screw(s) on the terminal plate.
(3) Using a ring connector fastener or pliers, securely
clamp each stripped wire end with a ring pressure
terminal.
(4) Place the ring pressure terminal, and replace and
tighten the removed terminal screw using a
screwdriver. (Fig. 1-4)

Examples of shield wires
(1) Remove cable coat not to scratch braided shield.
(Fig. 1-5)
(2) Unbraid the braided shield carefully and twist the
unbraided shield wires tightly together. Insulate the
shield wires by covering them with an insulation
tube or wrapping insulation tape around them.
(Fig. 1-6)
(3) Remove coat of signal wire. (Fig. 1-7)
(4) Attach ring pressure terminals to the signal wires
and the shield wires insulated in Step (2). (Fig. 1-8)
