9.1 Installation notes
9.2 Technical data
k
The choice of the cable, the installation and the electrical connection
must conform to the requirements of VDE 0100 "Regulations on the In-
stallation of Power Circuits with nominal voltages below 1000V", or the
appropriate local regulations.
k
Work inside the instrument must only be carried out to the extent descri-
bed and, like the electrical connection, only by qualified personnel.
k
If contact with live parts is possible while working on the instrument, it
must be isolated from the supply on both poles.
k
The electromagnetic compatibility (EMC) conforms to the standards and
regulations listed under Technical Data.
v Data Sheet T 95.5015
k
Run the input, output and supply cables separately, not parallel to one
another.
k
All input and output cables that are not connected to the mains supply
must be arranged as twisted and screened cables. Ground the screen at
one end on the instrument.
k
Earth the instrument at terminal PE to the earth conductor. This cable
must have the same cross-section as the supply cable. Earthing cables
must be run in a star configuration, to a common earthing point which is
connected to the earth conductor of the supply. Do not loop the earthing
cables, i.e. do not run them from one instrument to another.
k
Do not connect any additional loads to the supply terminals of the instru-
ment.
k
The instrument is not suitable for installation in hazardous (Ex) areas.
k
Inductive loads close to the instrument, such as contactors or solenoid
valves, should have RC modules fitted for interference suppression.
