General instructions

• •
Read this brief description through completely.
Then start the actual fitting.
Correct use of AS-i products
• •
AS-i products are designed for use exclusively in bus sys-
tems as agreed in the AS-i specifications. Use in any other
way is not in accordance with these specifications.
• •
AS-i bus systems and AS-i combi-sockets may only be in-
stalled by qualified personnel trained for this purpose.
• •
Detailed information on the concept and addressing of your
AS-i bus system can be found in the manual for the AS-i
master.
Before commissioning
• •
Switch off the power supply before connecting or disconnect-
ing plugs (otherwise functional damage may occur).
• •
Only commision combi-sockets which are completely fitted
and connected.
• •
Recommendation on symmetrizing/earthing.
The AS-i circuits of the AS-i combi-sockets have been de-
signed so as to be suitable for industrial environments with-
out the need for additional earthing. However, you can only
achieve the EMC values specified in the EU guidelines by
connecting an additional earth/ground cable to the M3
earth/ground screw. This also improves the symmetrizing of
the circuit and increases its stability.
• • If the AS-i master fails during operation, the outputs remain
set.
• • If the AS-i voltage of a slave is cut, the outputs are reset.
