2. Hardware Installation
A CNM001 module must be installed in the main RX3i rack in any slot except slot
0 or the expansion slot. A CNM001 module in an RX3i Universal Backplane can
be installed or removed while power is applied to the system (hot swapped).
This product is intended for use with the RX3i system. Its components are
considered open equipment [having live electrical parts that may be accessible
to users] and must be installed in an ultimate enclosure that is manufactured to
provide safety. As a minimum, the enclosure 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 (IEC60529) providing at least a pollution degree 2
environment. For use in hazardous areas, see 2.1, "Installation in Hazardous
Areas. "
WARNING
•
Inserting or removing a module with power applied to the system
may cause an electrical arc. This can result in unexpected and
potentially dangerous action by field devices. Arcing is an
explosion risk in hazardous locations. Be sure that the area is non-
hazardous or remove system power before removing or inserting
a module.
