DANGER!
The electrical connection must only be carried out by qualified personnel.
The choice of cable, the installation and the electrical connection must
conform to the requirements of VDE 0100 “Regulations on the Installation of
Power Circuits with Nominal Voltages below 1000 V” or the appropriate local
regulations. Only flexible cables and wires shall be used!
If contact with live parts is possible while working on the device, it must be
completely disconnected from the electrical supply.
Load circuits must be fused for the maximum relay current in each case, in
order to prevent welding of the relay contacts in the event of a short circuit.
The electromagnetic compatibility conforms to EN 61326.
Run input, output and supply cables separately and not parallel to one
another.
Use shielded sensor cables with twisted conductors. Do not run these cables
close to current-carrying components or cables. Ground shielding at one end.
Sensor leads should be implemented as uninterrupted cables (not routed via
terminal blocks etc.).
Do not connect any additional loads to the supply terminals of the device.
The device is not suitable for use in areas with an explosion hazard (Ex areas).
Apart from faulty installation, incorrect settings on the device may also affect
the proper functioning of the subsequent process or lead to damage. Safety
devices independent of the device should therefore always be provided and
should only be capable of adjustment by specialist personnel.
