1.3.2Wiring instructions

1)Terminals, SE and 5 are common to the I/O signals isolated from each other. Do not ground them.

Avoid connecting the terminal SD and 5 and the terminal SE and 5.

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.
