3.1 Installation notes
a
The choice of cable, the installation, the fusing and the electrical connection of the instrument 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.
a
The electrical connection must only be carried out by qualified personnel.
a
The electromagnetic compatibility conforms to the standards and regulations listed under Technical data.
a
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.
a
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.
a
Do not connect any additional loads to the supply terminals of the instrument.
a
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 all poles
from the supply (e.g. via a separate mains supply switch).
