WARNING
► Do not open the devices.
► Do not insert any objects into the devices.
► Prevent metal foreign bodies from penetrating.
6 Electrical connection
The device must be connected by a qualified electrician.
The national and international regulations for the installation of electrical equipment
must be adhered to.
► Disconnect the system from power and connect the unit.
The unit is only suitable for operation using SELV/PELV voltages.
For UL applications:
► To connect the IO-Link master, only use cables ranging from AWG 26 to 12 and
with a temperature range of -25...75 °C.
The circuits are insulated from each other and from device surfaces that could be
touched by means of basic insulation (according to IEC 61010-1, secondary circuit
with max. operating voltage, supplied from mains circuit up to 300 V of overvoltage
category II). The RJ45 interfaces are designed for network environment 0 according
to IEC TR62102.
→ Technical data.
► Do not use the device beyond the limits of the technical data.
6.1 IO-Link connection
The connected IO-Link devices must be supplied exclusively via the AL19x0
masters.
Any additional supply U
A
for class B operation must be electrically isolated from
the circuit U
S
of the AL19xx while assuring basic isolation (according to IEC
61010-1, secondary circuit with max. 30 V DC, supplied from mains circuit up to
300 V of overvoltage category II).
6.2 Wiring
Connect the IO-Link master to 24 V DC (20...30 V SELV/PELV) via port X31.
