4 Electrical connection
4.1 Installation notes
A The instrument is fitted with electronic components that can be destroyed by electrostatic discharge.
It is therefore important during mounting, maintenance and servicing that personnel working on the instrument
have adequate electrostatic discharge protection.
a All incoming and outgoing lines without a connection to the mains supply must be laid with shielded and twisted cables.
Lay the shield to ground potential on the device side.
a If possible, do not lay the input and output cables close to components or lines through which current is flowing.
a The instrument is not suitable for installation in areas with an explosion hazard.
a Do not connect any additional consumers to the screw terminals for the instrument supply.
a Both the choice of cabling material for installation and the electrical connection of the instrument must comply with the
relevant local or national regulations.
a Suitable measures must be taken to protect the relay circuit.
The maximum contact rating is 230 V / 3A (resistive load).
a Electromagnetic compatibility conforms to the standards and regulations cited in the technical data.
v Chapter 8 “Technical data”
a When connecting the device to an external PELV electrical circuit, the existing internal SELV electrical circuit becomes a
PELV electrical circuit whereby the protection against electrical shock is provided through double/reinforced insulation
and voltage limitation – but here no connection to the protective ground is required.
V Electrical connection must only be carried out by qualified personnel.
A Approval to EN 14597 is only valid if the correct sensor with DIN approval is set up and connected at configuration
level.
