EN | 5 About these instructions 1 4 Correct use The strain relief ZSE90 is a component offering effective support of a vertical cable system with integrated maintenance of electrical function according to DIN 4102 Part 12. A vertical cable system, in which cables for the maintenance of electrical function are installed on wall or vertical ladders with single clips or clamp clips, must be given effective support at distances of maximum 3.5 m. In cases of fire, the strain relief insulates the fastening material and cables. Depending on the maintenance of elec- trical function class, the cable jacketing in the area of the strain relief my not burn for up to 90 minutes. In this area, cable cannot slip and remain permanently fixed in single or clamp clips. Thus, the strain relief prevents possible cable tearing in cases of fire. The maintenance of electrical function is guaranteed for up to 90 minutes, depending on the function maintenance class. The ZSE90 strain relief is approved as a standard cable structure for the vertical routing of cables with vertical ladders, on profile rails with clamp clips and with single clips (designated as cable spacer clips in these instructions). Maintenance of electrical function classes E30 to E90. The strain relief is not designed for any other purpose than the one described here. If the strain relief is installed and used for another purpose, any liability, warranty or damage claims shall be rendered null and void. 1 5 Applicable documents – Surveyor reports GS 3.2/17-361-1-r1 and GA-2020/049-Nau – General type approval Z-19.53-2391, PYROPLUG® Block – General type approval Z-19.53-2338, PYROSIT® NG – Safety data sheets at www.obo-bettermann.com: – ASX ablation coating – PYROSIT® NG fire protection foam – PYROPLUG® Block foam block – FBA-SP filler 1 6 Basic standards and regulations – DIN 4102 Part 12 1 7 General safety information Observe the following general safety information on handling the system: – Ensure that the installation of the strain relief does not compromise the stability of the adjacent element – even in the event of a fire.
