Protection system according to EN 60529


IP 54






IP 65

for double door swichgear cabinets
Dust protection: The entry of dust is not completely prevented, however the amount is small enough that a satisfactory operating mode is maintained.
Protection against water Spray: Water, regardless from which direction it comes in contact with the housing, will not have any damaging effects. No water will enter.


for single door swichgear cabinets and protective boxes
Dust tight: No entry of dust
Protection against water spouting: Water, regardless from which direction it comes in contact with the housing, will not have any damaging effects. No water will enter.




Scheme of transport and installation

Series ESK

1) brackets for transport, 600 kg per bracket
2) Ropes
3) tightener
4) cross beam hook distance: witdt of cabinet +200 mm
5) foundation
6) cross girder when width of cabinet is more than 2,50 m

The foundation must be erected by customer and the static must be adjusted to the local requirement.

All transport-brackets must be taken up by the rope.
Rope must be tightened symmetrical.
Bearing of cabinet base frame on foundation all over.

Advice for transport with fork-lift

In most cases the bottom-frame of the cabinet has an insulation with PU-foam.
During transport and unloading the cabinet please take care that the insulation doesn`t get damaged by the fork-lift.
The lenght oft he forks must be longer than depth of cabinet, otherwise there is a chance of damage.
