Reversibility
b
b
Full reversibility: this means that cables can be added/ removed easily
without losing their initial characteristics, such as water tightness.
b
b
Medium reversibility:
for soft membranes, once the cable has been removed,
there may be a loss of IP depending on the size of the cable and the cut. For hard
plastic entries or combined material entries, initial characteristics are regained by
adding plugs.
b
b
Low reversibility:
the cable entry must be completely replaced in order to regain
the initial characteristics.

Degree of protection (IP)
If an enclosure is to be used in a clean, dry and well insulated environment, lower
levels of IP may be acceptable (IP54 or IP55).
In a dusty environment you may require higher IP levels, such as IP65 or IP68
(see expert’s tip 4, page 273).
8 -
Cable retention
Choose the right level of cable retention according to your needs. For locations
accessible to the public, preferably choose a high level of cable retention.
9 -
Cable diameter
Choose the cable entry seal according to the cable diameter.
Take into account cable diameter tolerances.
10 -
Cable installation time
Each cable entry has different installation characteristics. Some can be installed
easily and quickly thanks to the soft membrane. Take this into account depending
on labour costs in your region.
