1. General safety Information
kg
r
If cable support systems are touched with bare hands, then cutting could result on account of the
sharp edges. Always wear suitable protective gloves when handling system parts.
When working with the cable support system, in particular during shortening, e.g. with an angle
grinder, splinters and chips may result, which can cause injury. For this reason, wear personal
protective equipment (PPE) during mounting.
If the maximum load capacity is exceeded, the cable support system may collapse. Comply with
the load limits!
Cables can be damaged on bending. When inserting the cables, ensure that the minimum
bending radius, prescribed by the cable manufacturer, is observed.
