Degree of protection and type of fixation
Applies to both centralized and decentralized designs:
The degree of protection, which you decide on, is dependent on the type of
fixation:
Protection Class IP65
This degree of protection is achieved by fixing the operating unit by means of
clamping saddles together with a seal running around the circumference.
Protection Class IP54
This degree of protection is achieved by fixing the operating unit by means of
screw mountings.
Select the degree of protection in accordance with the intended use of the
equipment and, thus, the type of fixation. After having made the selection, chose
the necessary installation cut-out.
Note
The Panel PC 670/870, 12" touchscreen is not designed for installation using
