(2) Control circuit terminal layout

Terminal screw size : M3.5

Tightening torque : 1.2N·m

When connecting three or more control cables to the No. 5 terminal, connect the accessory No. 5 terminal dedicated L-shaped jumper to the No. 5 terminal.

In this case no cable should be connected to

the screw in the part.

(3) Wiring instructions

1)Terminals 5, SD and SE are common to the I/O signals and isolated from each other. These common terminals must not be connected to each other nor earthed (grounded).

2)Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits (including the 200V relay sequence circuit).

3)Since the control circuit input signals are micro currents, use two parallel micro signal contacts or a twin con- tact to prevent a contact fault.

4)It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the

cables are run improperly, resulting in an operation panel or parameter unit contact fault.

5)The maximum wiring length should be 30m.
