Connection Examples

Disable unneeded inputs!
The I/O module (750-489) has very sensitive measurement inputs.
Disable the channel of unused inputs to avoid unwanted error messages.
Section "Configuration and Parameterization with WAGO-IO-CHECK" describes
how one channel, or the channel diagnostics of individual inputs, of the I/O
module can be switched on/off.
