Figure 19: Top fixation of IP00 plate in a cubicle
Further, fixation elements should be used halfway up the plate to increase the plate's
rigidity. This is illustrated in Figure 20 for Rittal cubicles.

The fixation elements must have sufficient mechanical strength to support the weight
of the plate.
Once the plate is securely fastened into the cubicle, earth connections must be made
from the plate to the cubicle. Earth cable section must be made in accordance with local
regulations but must minimum be of size 2.5 mm².
Next to mounting the plate into the cubicle, the PQF Manager user interface has to be
mounted on to the door. This can be done by following the guidelines presented next
(Figure 21).
