● When connecting or changing internal connection cables, always observe the minimum
air clearance of 5.5 mm.
● Avoid protruding cable ends.
● Seal unused cable entries and screw in sealing elements so that they are secure and
airtight.
● Check seals and sealing surfaces of the terminal box or connector to ensure that the
degree of protection is maintained.
● Take measures to ensure that connecting cables cannot rotate, are not subject to strain
and pushing force and also provide anti-kink protection. Connectors must not be subject
to continuous force
● The coding slot for the plug-in connections must be aligned when inserted into the socket
connector. The union nut must be tightened by hand up to the endstop.
● The insulating film must be present in the terminal box.
● Make sure that the cable shields are properly connected.
Current-carrying capacity for power and signal cables
The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing
types B1, B2, and C under continuous operation conditions in the table with reference to an
ambient air temperature of 40°C. For other ambient temperatures, the values must be
corrected by the factors from the "Derating factors" table.
