5 Installation
5.1 Installation instructions
• 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 1000 V” and the relevant
local regulations.
• At maximum load, the cable must be heat resistant up to at least 80 °C.
• The device 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 circuits must be fused for the maximum load currents in each case
to prevent the relay contacts from becoming welded in the event of a short
circuit.
• Electromagnetic compatibility meets the requirements of EN 61326.
• Lay the input, output, and supply lines so they are physically separated
from each other and are not parallel.
• Use twisted and shielded probe cables. If possible, do not lay these cables
close to components or cables through which current is flowing. Ground
the shielding at one end.
• The probe cables must have an uninterrupted run (do not route them via
terminal blocks or similar arrangements).
• No other consumers can be connected to the power terminals of the
device.
• The device is not suitable for installation in areas with an explosion hazard.
• Apart from faulty installation, incorrect settings on the device may also
affect the proper functioning of the subsequent process or lead to damage.
You should therefore always provide safety equipment that is independent
of the device and it should only be possible for qualified personnel to make
settings.
