Connecting the Trunk
The multi-input/output is connected to the trunk line via designated screw or spring terminals.
Tip
Double-check that the correct torques are used when un- and reinstalling the terminal during
wiring activities!
Danger!
Explosion hazard from open or missing trunk terminal cover
If the device is installed Zone 2 and powered by a non-intrinsically safe power source, carrying
out hot work on the input/output terminals with an uncovered trunk terminal can lead to contact
with solid particles or tools. This can cause the live device to spark. The sparks can ignite the
surrounding potentially explosive atmosphere.
Ensure that the trunk terminal cover is present and correctly snapped onto the connector
housing to guarantee IP30 rating.
