3. 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.
• electromagnetic compatibility 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, parameter level data) may also
affect the proper functioning of controlled processes or lead to damage. provision should therefore always
be made for safety devices that are independent of the instrument, e. g. overpressure valves or temperature
limiters/monitors. adjustment must be restricted to specialist personnel (lock parameters for operation).
please observe the corresponding safety regulations in this matter. unfavorable parameter adjustment may
result in unstable control. The process value obtained 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 (via a separate mains supply switch, for instance).
