Wiring I/O Modules
A3.6.1
Re-checking Specifications
CAUTION
- Re-check the I/O specifications for the input/output modules. Note that applying a
voltage or current that exceeds the maximum permissible input voltage or current of
an input module or a voltage or current that exceeds the maximum switching
capacity of an output module will lead to machine failure, physical damage or fire
hazard.
- To avoid electrical shock, turn off the power before wiring.
- Make sure that the polarity of power terminals is correct.

To ensure that a system incorporating this module conforms to the CE Marking, use
shielded cables. By properly grounding the shield, noise emission and receipt will be
reduced. For more information on shielded cables, see Section A3.9.1 "Cable Routing
Considerations".
(2) Terminal Screws and Crimp-on Terminals
The I/O modules have an M3.5-screw terminal block each. The following crimp-on
terminals are recommended for connecting to I/O modules:
Under 7mm
