S7-400, M7-400 Programmable Controllers Module Specifications

A5E00069467-07

If you want to connect an S7-400 or M7-400 system to the public power system,
you must ensure compliance with limit value class B in accordance with
EN 55022.

Suitable additional measures must be taken, if you need to enhance the noise
immunity of the system as a result of high external noise levels.

S7-400/M7-400 modules surpass the requirements of IEC 61131-2 in respect of
shipping and storage requirements. The following details apply to modules shipped
and/or stored in their original packing.

The climatic conditions conform to IEC 60721, Part 3-3, Class 3K7 for storage and
IEC 60721, Part 3-2, Class 2K4 for transport.

The mechanical conditions conform to IEC 60721, Part 3-2, Class 2M2.
