Physical Installation - Allen-Bradley AADvance T9110 Safety Manual

Physical Installation

Although these modifications will not affect the system's operation until the
system configuration and application program have been modified, caution
shall be exercised to ensure that the modifications do not affect other safety
related functions.
The procedures to perform an on-line update are written in the AADvance
Configuration Guide(s), Rockwell Automation references
EN-P & ICSTT-RM-458-EN-P.
On-line modifications must follow the end users' MOC process as required by
the applicable industry safety standards. On-line modifications must include
any specific checks recommended by Rockwell Automation for the product.
IMPORTANT For Releases 1.3x onwards you can change the I/O module configuration
with an on-line update without having to stop the running application.
However, if you are still using an earlier product release the I/O module
configuration cannot be changed with an on-line update.
ATTENTION: Changes that affect the system's ability to respond safely, or
that may cause other plant disruption shall not be performed on-line unless
alternate protection measures can be implemented for the duration of such
modifications.
The installation environment is a potential source of common cause failure,
therefore it is vital that compatibility of the equipment with the environment is
known. The environment for these purposes includes the prevailing climatic,
hazardous area, power, earthing and EMC conditions. In many cases, there will
not be a single installation environment. Elements of the system may be
installed in differing locations; in these cases, it is important to know the
environment for each location.
ATTENTION: You must use installation and commissioning procedures that
comply with the applicable international or local codes and standards.
ATTENTION: The AADvance controller equipment (base units and modules)
is designed for use when it is installed upright, that is with the base units in a
vertical plane and the ventilation slots on the modules at the top and
bottom. This orientation is essential to ensure non-forced air cooling is
effective and the controller meets the specified MTBF of the modules. This
rule applies to all installations regardless of ambient temperature and any
additional forced air cooling that may be applied.
