DANGER
UNINTENDED EQUIPMENT OPERATION
Make sure to install the cables of the safety-related system according to ISO 13849-2.
Failure to follow these instructions will result in death or serious injury.

If short circuits and cross circuits can occur with the cables of the safety-related system and if they are not detected by upstream devices, protected cable installation according to ISO 13849-2 is required.

In the case of an unprotected cable installation, the two signals (both channels) of a safety function in short circuit state may be connected to external voltage if a cable is damaged. In this case, the safety function is no longer operative.
