①
so that its opening is 1 to 3 mm smaller than the diameter of the cable.
3. Pull the sealing insert over the end of the cable.
4. Prepare the end of the cable depending on the cable and its use, e. g. with a cable lug.
5. Connect the ends of the cables to the terminals in accordance with the circuit diagram.
The circuit diagram is located in the cover of the terminal box.
Refer to the "Connecting cables..." section for more information.
6. You might need to use a sleeve made of suitable sealing tape to modify the diameter where
it passes through the sealing insert. Push the sealing insert onto the prepared sleeve.
7. Insert the cable with the seal insert in position into the gland opening. Screw the strain relief
device together once the cable is in a concentric position in the gland opening.
8. Secure the strain relief device.
9. Tighten the clamping screws of the strain relief device so that the cable is clamped as
necessary, but do not damage the cable insulation. We recommend a torque of 5 Nm.
10.Retighten the clamping screws after 24 hours.
WARNING
Clamping screws for the strain relief clip
Tightening the strain relief clip clamping screws too tightly can damage the insulation. This
can cause a voltage flashover. This can result in death, serious injury, or material damage.
● Tighten the strain relief clip clamping screws to the specified torque.
