Relevant for usage under conditions that comply with the
the technical standard UL 60950-1:
Note: The following information applies only to device variants with
UL 60950-1 approval and protective conductor connection.
Protective conductor connection for the crimp connection:
Use a wire diameter for the ground conductor that is no smaller than the
diameter of the supply voltage connection, however of at least 0.75 mm²
(AWG18).
Use a professional crimping tool specified for the wire size. Follow the
instruction of the crimping tool. The pull out force the crimped connection
is at least 135 N according to the technical standard IEC 60352-2.
