10.2 Technical data
v
Data Sheet 70.6510
k
The choice of cable, the installation and the electrical connection must
conform to the requirements of VDE 0100 “Regulations on the
Installation 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
described and, like the electrical connection, only by qualified personnel.
k
The instrument must be disconnected on both poles from the electrical
supply if contact with live parts is possible while work is carried out.
k
Electromagnetic compatibility (EMC) conforms to the standards and
regulations cited in the technical data.
v
Data Sheet 70.6510
k
Run input, output and supply cables separately and not parallel to one
another.
k
All input and output cables without connection to the mains supply must
be arranged as twisted and screened cables. Earth the screen on the
instrument side to the earth potential.
k
Earth the instrument at the PE terminal to the protective earth conductor.
This cable must have the same cross-section as that used for the supply
cables. Earthing cables must be wired in a star configuration to a
common earth point that is connected to the protective earth conductor
of the electrical supply. Do not loop 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
instrument.
k
The device is not suitable for use in areas with an explosion hazard
(Ex areas).
k
Inductive loads close to the instrument, such as contactors or solenoid
valves, should have RC modules fitted for interference suppression.
k
The instrument must be provided with external fusing and disconnection.
Depending on the supply voltage, the following fuse values apply for the
external fusing:
20 — 53V AC/DC, 48 — 63Hz 5A fuse, slow-blow
110 — 240V AC +10/-15%, 48 — 63Hz 5A fuse, slow-blow
