Degree of protection
IP66 front panel (see note)
EN 60529
* The front face of the unit, installed in a solid panel, has been tested using conditions equivalent to the stan-
dards shown in the “Environmental conditions”. Even though the level of resistance unit is equivalent to these
standards, oils that should have no effect on the can possibly harm the unit. This can occur in areas where
either vaporized oils are present, or where low viscosity cutting oil are allowed to adhere to the unit for long
periods of time. If the front face protection sheet on the becomes peeled off, these conditions can lead to the
ingress of oil into the and separate protection measures are suggested.
If the installation gasket is used for a long period of time, or if the unit and its gasket are removed from
the panel, the original degree of the protection cannot be guaranteed.
