1 Safety
1.1 Indended Application
The VME system subrack, described in this manual, is indended as a platform
for a microcomputer system based on the VME bus system (VITA 1-1994).
The VME system subracks are designed for protection class IP 20 and can be
used only in the resp. environments.
For higher protection requirements, a.e. IP 54/55 you must install the system
subrack in a protective case.
VMEsystemsubracksare notend-products,sothereis novalidapprovalfor this
unit. In order to enable stand-alone functionality,additional elements are
required. An operational system is achieved only by way of appropiate VME
boards.
The completion and final testing of the units have been carried out, or at least
supervised, by qualified technicians. These instructions are directed exclusively
to these qualified technicians i.e.engineers, trained and qualified electricians
etc.
Make sure that:
• the assembled unit complies with the safety regulations currently applicable
in the country it is going to be used.
• the overall unit complies with all other regulations and specifications at the
place and country of use, e.g. interference limits, approval by the telecom-
munications authorities.
