WARNING!
Non-compliance with the electrical separation of the circuits
>
Risk of fire!
► Ensure that the circuits of US and UA are electrically isolated while assuring basic
isolation (according to IEC 61010-1, secondary circuit with 30 V DC maximum, supplied
from mains circuit up to 300 V of overvoltage category II).
► Ensure that the IO-Link devices and the connection technology support the electrical
separation.
► Connect the IO-Link devices to the ports X01 ... X08.
Maximum cable length per IO-Link port: 20 m
► Connect the IO-Link devices to UA with 24 V DC
(20...30 V SELV/PELV).
► To connect the IO-Link devices, only use cables with protection
rating IP 20 or higher.
