All the electrical connections must either be isolated from the mains supply by
a safety transformer according to EN/IEC 61558 with limited output voltage in
the event of a fault, or by other equivalent isolation measures.
The plug-in and coded terminals on the evaluation unit enable the cable
connections to be pre-assembled and so facilitate rapid final installation.
The H1/H2, ERR and OUT connections are not short circuit-proof.
If a common power supply is used, all the inductive and capacitive loads (e.g.
contactors) connected to the power supply must be connected to appropriate
interference suppression units.

Switching characteristics
2 safety outputs (relay outputs)
1 door monitoring output (semiconductor output,
not a safety output)
Notes on installation
The evaluation unit must be mounted in a control
cabinet with a minimum degree of protection of
IP 54. A snap-in element on the back of the
evaluation unit is used for fastening to the
standard rail (35 mm DIN rail).

The evaluation unit has a redundant switching
design with self-monitoring. This means that
the safety system is still effective even if a
component fails.
The door monitoring output OUT is not fail-
safe (not a safety output).
To ensure safety, it is imperative that the
safety outputs 13/14 and 23/24 are
connected.
