Installation notes
- The choice of cable, the installation, the fusing and the electrical connection must conform to
the requirements of VDE 0100 "Regulations on the Installation of Power Circuits with nominal
voltages below 1000V", or the appropriate local regulations.
- The electrical connection must only be carried out by qualified personnel.
- If contact with live parts is possible when working on the instrument, it must be isolated on
both poles from the supply.
- A current limiting resistor interrupts the supply circuit in the event of a short-circuit. The load
circuit must be fused for the maximum relay current in order to prevent welding of the output
relay contacts in the event of an external short-circuit.
- Electromagnetic compatibility conforms to the standards and regulations listed under
Technical Data.
- Run input, output and supply lines separately and not parallel to each other.
- Do not connect any additional loads to the supply terminals of the instrument.
- The instrument is not suitable for installation in hazardous areas.
- Apart from faulty installation, there is a possibility of interference or damage to controlled
processes due to incorrect settings on the controller (setpoint, data of parameter and
