Mounting and Grounding the Racks
Important Notes on Installation
The S7-400 racks are designed for wall mounting, mounting on rails, and for
installation in frames and cabinets. Their mounting dimensions comply with
DIN 41 494.
According to the UL/CSA and the EU Directive 73/23/EEC (low-voltage directive),
installation in a cabinet, a casing, or a closed operations room is necessary in order
to fulfil the requirements for electrical safety (see
Reference Manual
, Chapter 1).
In principle, the M7-400 is mounted like an S7-400 except that preassembly is
required (see Section 8.4 “Installing the M7-400”).
Step 1: Retaining Distances Between Devices
You must observe the minimum distances between the rack and neighboring
devices. You need these minimum clearances during installation and operation.
•
For fitting and removing modules
•
For fitting and disconnecting the module front connectors
•
To ensure the air flow required for cooling the modules during operation
The following figure shows the minimum space you must provide for a rack.
