Electrical connection

3.1 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 1000 V" or the
appropriate local regulations.
- The electrical connection must only be carried out by qualified personnel..
- If contact with live components is possible while 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 a short-circuit.
- Electromagnetic compatibility conforms to the standards and regulations listed under Technical Data.
- Input and output cables should be arranged as twisted cables, supply cables should be routed separately,
not parallel to one another.
- Do not connect any additional loads to the supply terminals of the controller.
- The instrument is not suitable for installation in hazardous areas.
- Apart from faulty installation, incorrect settings on the controller (setpoint, data of parameter and configuration
levels, internal adjustments) can affect the proper functioning of the subsequent process or lead to damage.
Safety devices independent of the controller, e.g. overpressure relief valves or temperature limiters/monitors
should always be provided, and only be capable of adjustment by qualified personnel. Please observe the
appropriate safety regulations in this matter.
