Understanding Your SLC 500/1746 Control System B-35

Once you have determined which way you will calculate the heat dissipation of

your modules, Refer to Example - Worksheet for Calculating Heat Dissipation

on page B-40. This worksheet shows you how to calculate the heat dissipation

for the example 1747-ACN15/-ACNR15 system on Page B-39. Once you feel

comfortable with the layout of the worksheet, go to the worksheet on

Page B-41 and fill it out for your control system.

Calculating the Power Supply Loading

Use the tables below to calculate the power supply loading for each chassis that

you have (step 1 of the worksheet).
