4.2.5 Leakage current
For asymmetrical power systems or if a phase fails, the
leakage current can increase to a multiple of the nominal value.
4.2.6 Locked-rotor protection
Due to the locked-rotor protection, the starting current (LRA) is
equal to or less than the nominal current (FLA).
4.3 Connection in terminal box
4.3.1 Preparing cables for connection
Only strip the cable as far as necessary, ensuring that the cable gland is
sealed and there is no strain on the connections. For tightening torques,
see Chapter 3.1 Product drawing.
NOTE
Tightness and strain relief are dependent on the cable
used.
→ This must be checked by the user.

Crimping and pressing forms of the wire-end ferrules
For flexible control and relay cables, from a cable cross-section
of 1.0 mm², a trapezoid crimp is required to ensure correct
installation on the connector.
