.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.
