7.1 Preparing the electrical connection
Requirements:
• Switch off the plant's voltage and secure it so that it cannot switch on again.
• Correctly prepare the connections for the voltage supply and signal processing. The device must be
equipped with an electrical circuit that meets the requirements of DIN EN 61010-1 with regard to
"Limited-energy circuits".
• Voltage supply: DC 18 to 30 V SELV, PELV.
• Use a cable that has a temperature resistance suitable for the process.
• Do not lay the cable near high-voltage or high-frequency cables; if you cannot avoid doing so, main-
tain a minimum gap of 30 cm.
