Cable management systems are electrical equipment in accordance with the Low Voltage Directive 2014/35/EU and may only be installed and maintained by qualified personnel or appropriately trained persons.
Cable tray systems are used exclusively for cable/routing. They must not be used by persons as a walkway, ladder or for other support.
Always wear suitable protective equipment to ensure safe handling during transportation and processing.
Deviations from the illustrations of the products are possible. However, this has no influence on the function and interaction.
The specifications of the valid usability certificates, such as German classification reports (abP), expert opinions, etc. must be complied with. Deviations from this require the approval of all responsible parties involved in the construction project prior to execution.
Applicable installation regulations must be observed.
Cable systems with integrated circuit integrity maintenance must be permanently marked by the installer.
When processing on site, care must be taken to ensure that there are no burrs; edge Protection Plates must be used if necessary.
On-site processing of stainless steel products only with suitable tools, post-treatment if necessary.
Length of cantilever bracket = width of cable support (cable tray, wire mesh tray, cable ladder). Any deviations from this must be approved by all those responsible for the construction project before execution.
Fittings and adjustable vertical couplers are not self-supporting and must be additionally supported at the joints as shown in the illustrations in this catalog.
The maximum permissible load is reduced by the weight of the cover if it is used.
When laying cables with B..., BU... and/or SAS... clamps, care must be taken to ensure that the cable is not damaged as a result of incorrect selection or over-tightening.
When laying single-core cables next to each other to prevent short circuits, do not use clamps made of ferromagnetic material for fastening.
SHS cable bundlers and LLK cable trunking are unsuitable for this purpose.
In the case of continuous vertical cable laying with clamps or risers over 3.5 m, an effective support measure against slipping must be taken in accordance with DIN 4102 Part 12, Section 8.3.
Cable laying materials subject to tensile stress must be dimensioned so that their calculated tensile stress does not exceed ≤ 9 N/mm² for E30 and E60 classifications and ≤ 6 N/mm² for E90 classifications in accordance with DIN 4102 Part 4, Table 11.1.
System components subject to shear stress must be dimensioned so that their calculated shear stress does not exceed ≤ 15 N/mm² for E30 and E60 classifications and ≤ 10 N/mm² for E90 classifications in accordance with DIN 4102 Part 4, Table 11.1.
The cable support systems (cable trays, cable ladders, wire mesh trays, cable trunking and system-related accessories) made of galvanized steel or stainless steel have electrical conductive properties that must be maintained throughout the entire system, even in the event of modifications or additions, in order to ensure equipotential bonding and the connection(s) to earth.
The circuit integrity maintenance of a cable system in accordance with DIN 4102 Part 12 is only guaranteed if the system is not negatively affected by surrounding components in the event of fire.
In the event of influences such as wind loads, cover cable rays or conductors must be installed outdoors with additional safety devices (self-tapping screws, steel straps, etc.).
In the case of mixed installation, the joint laying of functional maintenance cables for the safety power supply and cables (e.g. PVC cables) that are not subject to fire protection requirements, care must be taken to prevent the functional maintenance cables from overlapping with the other cables.
This can be achieved by using an RW barrier strip or by laying the cables on a separate level with the same cable support system. The design features and load limits of the cable tray systems in accordance with the valid German classification report (abP) must be complied with.
