Degree of protection and type of fixation Step 5

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
