.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.
