If the exhaust gas is to flow off into a collection line, observe the following points:
● Keep the flow resistance in the collection line as low as possible by using a short line or
by using a transition to a larger diameter.
● The exhaust gas line must be free of rapid pressure fluctuations. In case of pressure
fluctuations, take the following remedial actions:
– Install a separate exhaust line.
– Alternatively: Install a damping vessel (> 1 l) with a downstream restrictor between the
device and the exhaust line (pneumatic low pass).
● Route the line with a constant downward gradient to prevent congestion in the exhaust
gas line (e.g. due to water condensation) and therefore damage to the device due to
water formation. We recommend connection of a siphon as a water separator. The
exhaust gas line connected to the device must have an inside diameter of at least 8 mm
due to condensate formation.

5.4.1 Notes for electrical connections
Note
Improvement of interference immunity
•
Lay signal cables separately from cables with voltages > 60 V.
Use cables with twisted wires.
Install the device and lay its cables at a distance to strong electromagnetic fields.
Use shielded lines to guarantee the full specification according to Ethernet/PROFIBUS.
Note
Securing plug-in connections
Plug
-in connections without interlock can loosen and fall out.
Secure plug-in connections without interlock mechanically, for example, with a cable tie.
