Figure 4.8 – Device in Щ2 housing mounted in the control panel with 3 mm thickness 5 Electrical connections 5.1 Wiring recommendations To ensure the reliability of electrical connections it is recommended to use copper multicore cables, the ends of which should be carefully cleaned, tinned, otherwise use cable lugs before connection. Stripping of conductors must be performed in such way that the stripped ends after connecting to the device do not protrude beyond the terminal block. Cable cross section should be no more than 1 mm 2 . General requirements for connection lines:
• During the cabling, communication lines that connect the device with sensors must be isolated to a separate circuit (or several circuits) and placed separately from power cables or other sources of high-frequency and impulse interferences. 18
