3.1 Installation notes
• The choice of cable, the installation and the electrical connection
of the device 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 instrument shall be operated by mains protected with a branch
circuitry overcurrent protection device not more than 20 Amps.
For servicing/repairing a Disconnecting Device shall be provided to
disconnect all conductors.
• The load circuit must be fused for the maximum relay current, in
order to prevent the output relay contacts becoming welded in the
event of a short circuit occurring at that point.
• The electromagnetic compatibility conforms to the standards and
regulations cited in the technical data.
• Run input, output and supply cables separately and not in parallel
with one another.
• Sensor and interface cables should be shielded cables with
twisted conductors. Do not run cables close to current-carrying
components or cables. Ground the shielding on one side.
• Do not connect any additional loads to the supply terminals of the
device.
DANGER!
Hazardous electrical voltage.
Injury or death caused by electric shock.
The electrical connection must only be carried out by
qualified personnel.
