1-6 Installing Your 1394 SERCOS Interface System
System Mounting Requirements
There are several things that you need to take into account when
preparing to mount the 1394:
•
The ambient temperature of the location in which you will install
the 1394 must not exceed Environmental Specifications as shown
in Appendix A.
•
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 have to mount the system vertically.
•
You need to maintain minimum clearances (see Figure 1.2) for
proper airflow, easy module access, and proper cable bend radius.
•
The 1394 can operate at elevations to 1000 m (3300 ft) without
derating, however, the continuous current rating must be de-rated
by 3% for each additional 300 m (1000 ft) up to 3000 m (10,000 ft).
Consult your local Allen-Bradley representative prior to operating
at over 3000 m (10,000 ft)
Refer to Appendix A for mounting dimensions, power dissipation, and
environmental specifications for the 1394.
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.
