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.
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.

Direction of opening
The actuators and read heads CEM... can
only be used with the evaluation units given
above.
The plug connectors S1 and S3 are suitable
for snap-action and screw terminals.
For detailed information see the operating
instructions for the CES evaluation unit used.
The connection cable to the CES evaluation
unit must only must be extended using
EUCHNER plug connectors and adequate
consideration must be given to EMC during
assembly (see page 66). Intermediate ter-
minals must not be used.
Actuator and read head must be fitted so
that:
The surface of the solenoid and the mating
plate may become hot.
Protection against accidental contact or
adequate heat dissipation must be provided
by mounting the read head on metal.
The safety switch CEM... with solenoid is not
allowed to be used for the protection of
personnel as per EN 1088.
They are positively connected to the safety
guard, e.g. by using safety screws.
When the safety door is opened, the
actuator is moved in the axial direction (fron-
tal) away from the read head.
