Guidelines for Placing Power Supplies and Modules in a System

Placing Series A Digital and
Analog Modules

Always install modules in accordance with their specified operating temperature
ratings, as listed in

Appendix

, and provide a minimum of 5.08 cm (2 in.)

clearance above the modules.

Limit ambient temperature operation to 40 °C (104°F) if Series A POINT

Guard I/O modules are used without 1734-CTM spacer modules.

Figure 21 - Placing Series A Digital Modules for up to 40 °C (104 °F) Operation

In any system where you have any Series A POINT Guard I/O modules,

use a 1734-CTM spacer between every POINT Guard I/O module with
ambient operation between 40 °C (104 °F) and 55 °C (131 °F).

Insert a 1734-CTM module next to each standard I/O module (gray) if
that module’s thermal dissipation specification is more than 1 W.

Figure 22 - Placing Series A Digital and Analog Modules for Operation from
40 °C (104 °F)…55°C (131°F) max.

When using Series A POINT Guard I/O modules in your system limit the

power supply to 24V DC maximum, to limit the Series A POINT
Guard I/O module’s thermal dissipation.

for more information.

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.

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

For Vertical installations, be sure that 1734-CTM spacer modules are installed next
to any Series A POINT Guard IO modules operating above 40 °C ambient.
