Notes on the electrical connection

Housing for DIN rail mounting, IP 20
Relay output
4 read heads can be connected
In combination with read head CES-A-L... and actuator CES-A-B..
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 connections H1a/H1b ... H4a/H4b 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.

Subject to technical modifications; no responsibility is accepted for the accuracy of this information.
Switching characteristics
2 safety outputs (relay outputs)
4 door monitoring outputs (semiconductor
outputs, not safety outputs)
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 outputs O1 ... O4 are
not fail-safe (not safety outputs)
To ensure safety, both safety outputs 13/14
and 23/24 must always be evaluated.
