Switchgear Cabinet Assembly

Note

Information on EMC-conforming assembly and construction is provided within the overall functions section System Assembly, Construction and Connection.

PLC enclosure

Attention

:strong:PLC damage due to wrong enclosures

Due to their construction (degree of protection IP 20 according to EN 60529) and their connection technology, the devices are suitable only for operation in enclosed switchgear cabinets.

To protect PLCs against:

• unauthorized access,
• dusting and pollution,
• moisture and wetness and
• mechanical damage,

switchgear cabinet IP54 for common dry factory floor environment is suitable.

Maintain spacing from enclosure walls, wire-ways, adjacent equipment, etc. Allow minimum 20 mm of space on all sides, as shown. This provides ventilation and electrical isolation.

Basically, it is recommended to mount the modules on an earthed mounting plate, independent of the mounting location.

Installation of AC500/S500 modules in a switch-gear cabinet

Attention

Horizontal mounting is highly recommended. Vertical mounting is possible, however, derating consideration should be made to avoid problems with poor air circulation and the potential for excessive temperatures (see also the AC500 system data, operating and ambient conditions, for reduction of ambient temperature).

Note

By vertical mounting, always place an end-stop terminal block (e.g. type BADL, P/N: 1SNA399903R0200) on the bottom and on the top of the modules to properly secure the modules.

By high vibration applications and horizontal mounting, we also recommend to place end-stop terminals at the right and left side of the device to properly secure the modules, e.g. type BADL, P/N: 1SNA399903R0200.
