Note on material damage
The EMC cable glands from Pflitsch can be damaged if the permissible tightening torques are
exceeded when the cable glands are tightened.
•
Observe the permissible tightening torques.
•
Use a suitable torque wrench from Pflitsch to tighten the screws.
The procedure for using cable lugs for switchgear connections is described here.
Tip: Check whether the cable lugs fit through the double nipple of the EMC cable gland before you
create the cables/wires. Prepare the cables/wires accordingly.
