*Information on bar terminals
Introduced products (as of April, '02): Phoenix Contact Co., Ltd.
Bar terminal crimping tool: CRIMPFOX ZA3 (Phoenix Contact Co., Ltd.)
1)Terminals SD and SE are common terminals of the I/O signals. Do not earth
(ground) these common terminals.
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.
