Inserting the cable into the terminal box
1. Only use cable entries that are suitable for the cable.
2. Only use suitable cable entries and cables for the prevailing ambient temperature.
3. Ensure that the power cables are strain relieved where they enter the terminal box.
4. Carefully connect the cable and ensure a reliable protective conductor connection.
5. Tighten the glands and the elements for the strain relief with the torque specified by the
manufacturer.
6. Check the cable glands and cables to ensure that they are correctly sealed and firmly
seated.
7. Correctly close and seal threads or holes that are not being used ensuring that the IP degree
of protection is maintained. The IP degree of protection is specified on the rating plate.
6.2.3
Connecting cables with cable lugs
1. Select the cable lugs according to the required cable cross-section and stud size.
The cable cross section that can be connected is determined by the type of cable lug. The
range of external diameters for the connecting cable is limited by the cable entry that is
used. The data are listed under "Technical data". Connect only one conductor per cable
lug.
2. Insulate the conductor ends in such a way that the remaining insulation reaches almost up
to the cable lug.
3. Fasten the cable lug to the end of the conductor correctly, e.g. by squeezing.
4. Insulate the cable lug sleeves where necessary to ensure minimum air clearances
5. Place the cable lug on the bolt as shown in the schematic diagram below. Take note of the
arrangement of any disconnecting link used, and tighten the contact and fastening nut to
the appropriate tightening torque. When doing this, restrain the bolts so they do not twist.
6.2.4
Minimum air clearances
When making electrical connections, maintain minimum air clearances for bare electrically live
components. The rated voltage can be found on the rating plate.
