Guidelines for Placing Power Supplies and Modules in a System Chapter 3
To implement a system containing only 1734-IB8S Series B and 1734-OB8S
Series B POINT Guard I/O modules (no POINT Guard I/O Series A modules
used), follow these guidelines.
• Series B POINT Guard I/O modules are used without 1734-CTM spacer
modules with ambient operation up to 55 ° C (131 ° F) See Technical
Specifications for Series B Modules for Series B POINT Guard I/O
module derating requirements for every module with ambient operation
between 40
° C (104 ° F) and 55 ° C (131 ° F).

ATTENTION: Vertical orientation requires careful attention to design details
and panel layout so that all modules in the stack operate within their rated
operating temperature range.
