Electrical installation and Wiring
Warning
Risk of injury due to unintentional switch on of power supply or uncontrolled restarting of the
installation.
▶ Take appropriate measures to avoid unintentional activation of the installation.
▶ Guarantee a set or controlled restarting of the process subsequent to any intervention on the device.
• Use a filtered and regulated 12...36 V DC power supply. The circuit has to be safety extra low voltage
(SELV), with a safe energy level.
• Make sure the installation is equipotential. See chap. 8.3.
• Do not install the cables near high voltage or high frequency cables; if a combined installation cannot be
avoided, a minimum space of 30 cm should be respected.
• Protect the device power supply by means of a 300 mA fuse and a switch.
• Protect the power supply of each transistor output by means of a 125 mA fuse.
• Protect the relays by means of a max. 3 A fuse and a circuit breaker (depending on the process).
• Do not apply both a dangerous voltage and a safety extra-low voltage to the relays.
Insert the supplied stopper gaskets into the unused cable glands to ensure the tightness of the device.
