REMARKS

For the cable size, wiring length, etc., refer to the instruction manual (basic).

1.6.2 Wiring instructions

1)Terminals SD, SE and 5 are common to the I/O signals. These common terminals must not be earthed.

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)The input signals to the control circuit are micro currents. When contacts are required, use two or more parallel micro signal contacts or a twin contact to prevent a contact fault.
