[16] Test report

The proof of explosion protection is recorded in detail in the test report IB-12-3-214. The test docu-

ments are part of the test report and are Iisted there.

Summary of the test results:

The Junction enclosures types Klippon POK ...Ex fulfil the requirements of explosion protection for

equipment group

and category 2G, type of protection Increased Safety and Category 2D with

Protection by enclosures and Intrinsic safety.

Safetv technlcal notes

The conditions specified in the EC-Type Examination Certificates of the Ex components have to

be taken into account for the installation of these components in the enclosure.

The degree of protection, at least IP 64 for dusU IP 54 for gas, at the installation and operation is

reached only at the proper use of cable glands which are tested and confirmed on explosion

protection.

[17] Special condltlons for safe use

The applicable temperature ranges for the ambient temperature depending on the temperature

class

max. Surface temperature must be observed.

The values are maximum values, the actual electrical values are determined by the built-in com-

ponents. The manufacturer fixes the definite rated values in the context of these limiting values.

So the manufacturer ensures the compliances with the maximum surface temperature and the

permissible operating temperature of the components.

[18] Essential Health and Safety Requlrements

Confirmed by compliance with standards (see [9]).
