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.
- The electromagnetic compatibility (EMC) conforms to the standards and regulations listed under Technical Data.
- The instrument is not suitable for installation in areas with an explosion hazard and must be built into a housing that
provides protection against fire/electrical hazards.
- Apart from faulty installation, incorrect settings on the instrument (setpoint, data of parameter level) may also affect the
proper functioning of controlled processes or lead to damage. Provision should therefore always be made for safety
devices independent of the instrument, e. g. overpressure valves or temperature limiters/monitors. Adjustments must
be restricted to specialist personnel (lock parameters for operation). Please observe the corresponding safety regula-
tions in this matter. Unfavorable parameter adjustments may lead to unstable control. The resulting process value
should therefore be monitored for its stability and knowledge about the process should be obtained.
- 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.
- Do not connect any additional loads to the supply terminals of the instrument.
- The external fuse of the supply should not be rated below 1A, depending on the conductor cross-section.
If contact with live components is possible while working on the instrument, it must be disconnected on both poles
from the supply (e.g. via a separate mains supply switch).
