Placing Series B Digital
Modules
Always install modules in accordance with their specified operating temperature
ratings, as listed in Appendix C
, and provide a minimum of 5.08 cm (2 in.)
clearance above the modules.
When used in a system that contains only Series B Guard I/O modules, series B
Guard I/O modules are used without 1734-CTM spacer modules in
environments with ambient operation up to 55 °C (131 °F).
