2 Correct use
The screw-on cable tray systems are used to support and route all kinds
of cables, taking the approved load values into account. Depending on
the corrosion protection used, they can be mounted both indoors and
outdoors.
The cable tray systems are suitable for use at ambient temperatures
of ‒20 °C to +120 °C. At temperatures below ‒20 °C, the material will
become brittle and may not be processed further.
The screw-on cable tray systems are not designed for any other purpose
than the one described here. If the screw-on cable tray systems are used
for another purpose, any liability, warranty or damage claims shall be
rendered null and void.
3 Safety
3.1 General safety information
Observe the following general safety information:
– Only have electrical work carried out by specialist personnel with elec-
trical training.
– Risk of cutting from plate edges. Wear protective gloves.
– Design the screw-on cable tray systems according to the loads to be
expected.

System overview
4 System overview
4.1 System description
The screw-on cable trays for routing cables are designed for high sup-
port loads. The widths vary between 100 and 600 mm and the side
heights between 35 and 110 mm. The cable trays are screwed together
using connector holes with the appropriate fastening material. The selec-
tion of the matching cable tray system is dependent on the area of use
and the cable load and volume to be routed.
The following screw-on cable tray systems are available with hot gal-
vanised (FS) and hot-dip galvanised (FT) and stainless steel (A2/A4)
surfaces:
– MKS medium-duty cable tray system
– SKS heavy-duty cable tray system
– DKS perforated cable tray system
– EKS extra-heavy-duty cable tray system
– IKS industrial cable tray system
The screw-on cable trays are available in perforated and unperforated
versions. The systems include countless connectors, fittings, such as
bends, branches, tees and reducers, cross-overs, as well as covers and
other accessories.
The cable tray systems can be mounted on floors, walls and ceilings
on various support systems. The mounting of the support systems is
described in separate mounting instructions, see “1.6 Applicable docu-
ments” on page 6.
