Premium PLC protection processing

General points

PLCs in the Premium and Atrium range meet AP (all-climate processing) processing requirements.

For installations used in industrial production workshops or in environments which come under the title HP (processors in heat and humidity) processing, the Premium PLCs must be inserted into a protection casing (minimum IP54 as outlined by standards IEC 60664 and NF C 20 040).

Premium PLCs have an IP20 protection index. They can thus be installed without a protection casing in restricted-access areas which do not exceed Pollution Degree 2 (control room free of machines or any activity creating dust).

The Atrium card is designed for integration into a host PC. The host device must therefore conform to the IP20 protection index.

CAUTION

RISK OF LOSS OF IP20 PROTECTION INDEX

For a rack to conform to the IP20 protection index, the unoccupied module slots must be protected by a TSX RKA 02 protection cover.

Failure to follow these instructions can result in injury or equipment damage.
