Notice to Users of the SYSMAC CP1 I/O Units in the USA and Canada
Please observe the following installation information instead of the general information in the instruction manuals in
order to use the product under the certified conditions of UL and CSA when the products are installed in the USA
and Canada. These conditions are according to the National Electrical Code in the USA and the Canadian Electrical
Code and may vary from information given in the product manuals or safety precautions.
I/O Wiring
Do not use crimp terminal for I/O wiring. Tighten the screw directly on the solid wire.
Do not insert more than one wire in one terminal.
Tightening torque: 4.4 Lb In. (0.5 N·m)
Wire range: AWG 26 to 18 (Solid wire only)
Surrounding Air Temperature
Rated temperature: 55
