Rockwell Automation 141A Mounting System Temperature Rise Calculation Software Tutorial - Manual (Page 11)

In our Tutorial Project, we want to enter the dimensions manually. Confi gure your enclosure as
in the screen shot below:
Th ere are three possibilities to enter or to calculate the power loss:
1. If known, enter the power loss manually. Example: Th ere is only one big drive in one panel.
2. From temperature measurements. Example: Th ere is an existing panel and tests show that
the inside temperature exceeds the limits. TRCS can help to evaluate the required measures
to be taken (e.g. openings, ventilation or cooling fans) to meet the requirements.
3. Evaluation by use of the power loss data of the individual components and conductors.
In this Tutorial Project, we want to use method 3. Usually, this can be time consuming if a
panel contains a lot of diff erent components with diff erent operating currents. But with this
method, the software provides the capability to import component lists we have generated
with MCS Star. Of course, some additional components and the power conductors still need
to be entered or selected manually.

Power Loss
Number of enclosures: 1 •
Enter the dimensions manually: W = 1,000, H = 1,400, D = 400 mm •
Confi gure the type of installation: rear face covered, all other surfaces free •
Note: Th e term “covered” means the enclosure surface is against another structure such as the wall of
the building or another enclosure.
