ATTENTION
Safety-based devices must be suitable for safety-relevant signals!
An interruption in the function of safety outputs will lead to a loss of safety functions, which
means that there will be a risk of severe injury.
• Do not connect any loads that exceed the rated values of the safety outputs.
• Wire the samosPRO system such that no 24 V DC signals can unintentionally make
contact with the safety outputs.
• Connect the GND lines of the power supply to ground so that the devices do not switch
on when the safety output line is at ground potential.
• Use suitable components or devices that fulfill the applicable guidelines and standards.
• Actuators can be wired at the output as single-channel. To ensure that the corresponding
safety integrity levels can be adhered to, the lines must be routed such that short-circuits
to other signals can be prevented, e.g. by routing them within protected areas such as
switchboxes or in separate shielded cables.
