PC3000 - Installation Guide
The Racking System
The M5 ‘A’ fixing centres are recommended for use in bulkhead (rear) mounting
applications in order to distribute the cantilever load over a wider area. They may
also be used in conjunction with the ‘B’ fixings to provide additional security.
The diagram below shows the ‘footprint’ of the rack on its’ mounting surface. The
rack backplane is covered by a metal shield and the brackets provide adequate
clearance.
Use 'A'. M5 fixing centres

Minimum clearance required in front of bulkhead is 330mm.
It is recommended that screws penetrate the nut or other threaded medium by at least
one diameter (i.e 5 or 6mm)
Extension racks and multi-rack systems
A multi-rack system comprises one main rack
plus 1 to 7 extension racks.
In order for the PC3000 racks to operate
without risk of over-heating, it is
recommended that racks, when stacked
vertically, be positioned at least
3U (133mm) apart.
When mounted adjacent to one another,
no spacing is required. It is also recommended
that the cabinet is vented and force cooled.
