MOTION-CONNECT connection systems
Introduction
General information
7
■
Function
(continued)
MOTION-CONNECT cables are tested in a cable carrier. The
cables are attached at one end by means of strain relief to the
moving ends of the cable carrier. Strain relief is applied over a
wide area of the cable jacket surface without crimping the cable.
Cables must be installed in accordance with the instructions
supplied by the cable carrier manufacturer.
Notes
:
If, for example, pre-assembled cables are installed in a cable
carrier in such a way that the connector would inhibit assembly,
pre-assembled cables without assembled connector can also
be supplied (power and signal cables
1)
). In this case, the con-
tacts of the cables are crimped and the connector enclosure is
supplied separately. After installing the cables, the customer
assembles the connector enclosure.
In case of vibration load and with horizontal or vertical cable
entries, we recommend that the cable is additionally fixed if
between the cable strain relief on the cable carrier and the
terminal at the motor part of the cable is hanging loose or is not
routed. To prevent machine vibrations being transmitted to the
connectors, the cable should be fixed at the moving part where
the motor is mounted.

Current carrying capacity for power and signal cables
The current carrying capacity of PVC/PUR-insulated copper
cables is specified for installation type C under continuous
operating 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 derating factors from the table.
