ATTENTION

Safety state of the module and its data is defined as the off state.

Serious injury can occur due to breakdown of safety outputs. Do not
connect loads beyond the rated value of the safety outputs.

Serious injury can occur due to loss of required safety functions. Wire
the module properly so that supply voltages or voltages for loads do
not touch the safety outputs accidentally or unintentionally.

As serious injury can occur due to loss of safety functions, use
appropriate devices as shown in the
