1-6 Installing Your Ultra3000
System Mounting Requirements
There are several things that you need to take into account when
preparing to mount the Ultra3000:
• The Ultra3000 must be enclosed in a grounded conductive
enclosure offering protection as defined in standard EN 60529
(IEC 529) to IP22 such that they are not accessible to an operator
or unskilled person, in order to comply with UL
®
and CE
requirements. A NEMA 4X enclosure exceeds these requirements
providing protection to IP66.
• The ambient temperature of the location in which you will install
the Ultra3000 must not exceed 55° C (131° F).
• You must install the Ultra3000 vertically on the panel (refer to
Figure 1.4 for mounting orientation).
• You must install the panel on a flat, rigid, vertical surface that
won’t be subjected to shock, vibration, moisture, oil mist, dust, or
corrosive vapors.
• You need to maintain minimum clearances (refer to Figure 1.4) for
proper airflow, easy module access, and proper cable bend radius.
•
The Ultra3000 can operate at elevations to 1000 m (3280 ft)
without derating, however, the continuous current rating must be
de-rated by 3% for each additional 300 m (984 ft) up to 3000 m
(9842 ft). Consult your local Allen-Bradley representative prior to
operating above 3000 m (9842 ft).
Refer to Appendix A for mounting dimensions, power dissipation, and
environmental specifications for the Ultra3000.
ATTENTION
!
Plan the installation of your system so that you can
perform all cutting, drilling, tapping, and welding
with the system removed from the enclosure.
Because the system is of the open type construction,
be careful to keep any metal debris from falling into
it. Metal debris or other foreign matter can become
lodged in the circuitry, which can result in damage to
components.
