In this chapter
we explain the steps required for the mechanical assembly of an S7-300.
Note
Note the installation guidelines and notes on safety in this manual when mounting,
commissioning and operating S7-300 systems.
Open components
S7-300 modules are "Open Components" according to IEC 61131-2 and EC
Guideline 73/23/EEC (Low-Voltage Guideline), and to UL/CSA Approval an "open
type".
In order to conform with specifications on safe operation relating to mechanical
strength, inflammability, stability and touch-protection, the following alternative
installation modes are prescribed:
• Installation in a suitable cubicle
• Installation in a suitable cabinet
• Installation in an appropriately equipped and closed operating area
Access to these areas must only be possible with a key or tool. Only trained or
authorized personnel is allowed access to these cubicles, cabinets or electrical
operating rooms.
