ATEX (Atmosphère Explosible) According to the European Directive 94/9/EC the equipment must not be used in explosion-risk areas.
Please note:
Electrical connection of actuator Flexible three-core cable, e. g. Ölflex Classic 110, manufactured by LAPP, 3 x 0.75 mm2 is required for wiring the
actuator.
Bus cable, cable length and size Multi-core twisted-pair control cable, e. g. UNITRONIC® BUS CAN 2 x 2 x ..mm²; Li2YCY 2 x 2 x ..mm2 must be used
as bus line.
Preassembled cable assemblies (with connector and coupler) of various lengths available as optional extra.
The cable length dictates the baud rate (data transfer rate) between the bus nodes, and the total power consumption
of the sensors dictates the conductor size.

The baud rate is set via code switch. Default baud rate setting of control element URZ 40a: 250 kbit/s (cable length
up to 125 m). For longer cable lengths reduce the baud rate setting accordingly. Make sure that all bus nodes feature
the same setting.
Voltage supply of CAN bus To guarantee trouble-free operation of the CAN bus system make sure that the voltage supply is sufficient for the
application. Please use the following table to check the supply voltages of your bus system.

If sum 2 exceeds sum 1 provide the CAN bus with a separate stabilised safety power supply unit (e. g. SITOP Smart
24 V 2.5 A) with 24 V DC. The power supply unit must meet the requirements of DIN VDE 0106 (safe isolation) and be
provided with an overcurrent protective device according to EN 61010-1/VDE 0411.
