Installing the Terminal Assembly

GFK-2749
The Terminal Assembly and PSM module are considered open equipment (having live
electrical parts that may be accessible to users) and must be installed in a protective
enclosure or incorporated into other assemblies manufactured to provide safety. As a
minimum, the enclosure or assemblies shall provide a degree of protection against solid
objects up to 12mm (e.g. fingers). This equates to a NEMA/UL Type 1 enclosure or an
IP20 rating providing at least a pollution degree 2 environment.
When this system is installed into an area designated as Class 1 Zone 2 in Europe,
compliance with the ATEX Directive requires an enclosure with a minimum rating of IP54.
The enclosure must be able to adequately dissipate the heat generated by all components
mounted inside so that no components overheat. Heat dissipation is also a factor in
determining the need for enclosure cooling options such as fans and air conditioning.
Due the the nature of the power systems monitored by the PSM
system, careful consideration must be given to the effects on these
systems before the PSM module is either hot-removed or
hot-inserted into the host controller backplane.
The PSM module must be installed in a main (CPU) rack in an RX3i system. For system-
level installation information, refer to the PACSystems RX3i System Manual, GFK-2314.
The IC694PSM001 Module can be hot-swapped in an RX3i backplane.
The Terminal Assembly must be securely installed on a rigid, conductive, 12 – 14 gauge
steel panel using four user supplied M4 - M5 or #8 - #10 SAE bolts. The Terminal
Assembly should be mounted near the host controller rack containing the PSM module,
close enough to accommodate the 2 meter interface cables provided.
After connecting the power system wiring and before applying
power, the plastic finger guards must be installed on the Terminal
Assembly.
