When connecting up using cable lugs, select their size corresponding to the required cable
cross-section and the stud size. An inclined arrangement is only permitted provided the
required air clearances and creepage distances are carefully maintained.
Remove insulation from the ends of the conductors so that the remaining insulation almost
reaches the cable lug.
Note
The direct contact between the cable lug surfaces and the contact nuts or contact screws
ensure that the connection can conduct current.
WARNING
Short-circuit hazard
Live conductors released from the terminal board can cause short circuits. Death or serious
injury can result.
• You must bend single-core line conductors into a U shape in order to prevent the
contact force being transferred at just one side.
• In order to prevent the cable lug from rotating, for a line connection using a cable lug,
angle single- or multi-core cables downwards through an angle of approx. 40°.
