8.2 Cable Entries into the Connection Compartment
The cable glands may only be used for connection of permanently laid lines.
IMPORTANT
If cable glands or cables that were not tested by Berthold Technologies
GmbH & Co. KG are used, the torques for fixing may need to be redefined.
The specified torques in the table are guidelines for the cable glands listed in the
table, but essentially depend on the cable used. The pressure screw and the fitting
body must be tightened so that the IP protection is securely guaranteed.
Only metallic cable glands may be used outside the temperature
range -20 °C ≤ T
a
≤ +60 °C, which are listed in the following tables.
Note the torques, cross sections and protective types of screw connections in the
following table.
The following table shows the installed threading for the cable entry:
