Electrical installation

Attention!
Electrical installation may only be performed by trained specialist
technicians.
Attention!
Each safe AS-interface slave is to be activated at least once per year
and the switching behaviour of the output circuits of the AS-interface
safety monitor visually inspected.
After replacing a safe AS-i slave, the new slave must be checked for
proper function; after replacing an AS-i safety monitor, the new AS-i
safety monitor must be checked for proper function.
Supply lines, signal lines and the AS-i bus line are to be laid
separately from power supply lines.
Suitable spark extinction must be used with contactors in the switch
cabinet.
For drive motors and brakes, observe the installation notices in the
corresponding operating instructions.
Maximum line length for the AS-i bus line is 100 m. For longer line
lengths, use AS-i repeaters.
Attention!
The AS-interface power supply unit for supplying the AS-interface
components must demonstrate safe mains separation acc. to
IEC 60742 and the ability to bridge brief mains failures of up to 20ms.
The power supply unit for 24 V supply must also demonstrate safe
mains separation acc. to IEC 60742 and the ability to bridge brief
mains failures of up to 20ms.
