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.
