Pre-assembled Cables - Setams SA

a In order to achieve the
longest possible service life of
the trailing arrangement and
cables, cables with different
materials and without separators
must not be used in the
trailing arrangement. The
sections should be filled
uniformly to ensure that the
cables do not change their
positions during operation. The
cables should be distributed
as symmetrically as possible,
according to weight and
dimensions. Cables with
greatly differing outer
diameters should be
segregated by separators.
When routing cables with
integral connectors in a trailing
arrangement, do not pull at
the connector as this may
damage the strain relief or
cable clamp.
s The cables must not be
secured in the trailing arrangement
and must have freedom
of movement.
d It must be possible to move
the cables without force,
particularly in the radii of
curvature of the arrangement.
The bending radii must not be
less than the minimum values
specified.
Mounting points of the cables
should be located in dead
zones at both ends at a suitable
distance from the end points of
the moving parts.
Note:
If, for example, pre-assembled
cables are laid in a trailing chain
and the connector obstructs
installation, the pre-assembled
cables can also be ordered and
supplied without connector
(signal and power cables).
In the case of this cables, the
contacts are crimped; here, the
connector housing is not
mounted, but enclosed as part
of the delivery. After installing
the cable, the customer mounts
the connector housing himself
(see 2/4 and 2/5 for ordering).
f The cables must be fitted
with a strain relief, at least at
the moving ends of the trailing
arrangement; this should be
achieved over a large area of
the sheath’s surface without
crushing the cable
construction.
g Twisting must be avoided
when removing the cables from
the cable drum, i.e. the cables
must be rolled off and must
never be lifted in loops over the
drum flange.
When routing the cables, the
instructions given by the trailing
arrangement manufacturer must
be strictly observed.
Our cables are approved for a
lifting height of max. 5 m.
In the case of vibration load and
horizontal or vertical cable
entries we always recommend
additional fixing of the cable, if
part of the cable is freely
suspended or is not ducted
between the strain relief on the
trailing arrangement and the
connection to the motor. To
avoid machine vibrations being
transferred onto the connectors,
the cable should be connected
to the part in motion, where the
motor is connected, too. The
distance should be approx.
10 x Dmax of the cable.
