6 Electrical connection
6.1 Installation notes
Qualification of personnel
• The electrical connection must only be carried out by qualified personnel.
Electrical wiring
• When selecting the electrical wiring material as well as when installing and
connecting the device electrically, comply with the requirements of DIN VDE
0100 "Low-voltage electrical installations" and the applicable country-specif-
ic regulations (e. g. based on IEC 60364).
• The input, output, and power supply lines must be separated from one an-
other spatially and not laid in parallel.
• Select suitable cables for sensors and interfaces (shielded and twisted or co-
axial cable). These lines must not be installed near live electrical compo-
nents or current-carrying wiring.
• Sensor lines must be uninterrupted (not connected via terminal blocks or the
like).
• Provide shielding in accordance with the connection diagram on the device.
• In a star wiring configuration, grounding wires must be connected to an equi-
potential grounding busbar and insulation must be intact. Keep lines as short
as possible. Ensure proper potential equalization/bonding.
Electrical safety
• Disconnect all phases of the power supplied to the device (power grid, out-
side power supply sources for relays/solid state relays etc.) If current-carry-
ing components could be touched while work is being performed.
• Fuses for power supply circuits should be rated at no more than 10 A (slow-
blow).
• To prevent destruction of device outputs in the event of an external short cir-
cuit, short-circuit currents in circuits with relay or semiconductor outputs
should be limited through use of appropriate fuses.
• The device is not suitable for installation in potentially explosive atmo-
spheres.
• Besides incorrect installation, wrong settings on the device can adversely af-
fect performance of the connected process. For this reason, independently
operating safety devices, e.g. pressure relief valves, temperature limiters/
monitors, liquid-metering limiters and overflow prevention devices should be
provided and adjustment of them restricted only to train technical personnel.
Appropriate safety regulations must be observed in this connection.
• Plug-in screw terminal strips should not be unplugged until after the power
has been disconnected.
