Risk of death or serious injury.
S7–400 modules are classified as open equipment, meaning you must install the S7–400 in
an enclosure, cabinet, or switch room that can only be accessed by means of a key or tool.
Only instructed or authorized personnel are permitted to access these enclosures, cabinets,
or switch rooms.
Additional information
The components of the standard S7-400 system, e.g., power supplies, I/O modules, CPs,
and FMs, are also used in the high availability S7-400H automation system. For a detailed
description of all hardware components for S7-400, refer to Reference Manual
