2.4 Installation notes
• The device is not suitable for installation in explosive areas (Ex areas).
• The choice of cable material, the installation and the electrical connection of the device must
conform to the requirements of DIN VDE 0100 "Installation of low-voltage power circuits"
and/or the appropriate local/national regulations (e.g. based on IEC 60364).
• At maximum load, the cables must be heat resistant up to at least 80 °C.
• The electrical connection must only be carried out by qualified personnel.
• The device is intended to be installed in electrical cabinets or systems. It 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 conduc-
tors.
• The load circuit must be fused for the maximum relay current, in order to prevent the output
relay contacts from becoming welded in the event of a short circuit occurring at that point.
• The electromagnetic compatibility (EMC) meets 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 other consumers to the power terminals of the device.
