Determining Power Consumption
Use
Table 3-1
to identify and
Table
3-2
to calculate the power
requirements for the configuration of your FB107. If the power input is
not sufficient, you must either provide an alternative power supply for
external devices or reduce power demands. See
Table 3-3
for an example
of a completed power consumption worksheet.
Note:
The worksheet shown in
Table 3-2
is available to registered users
as a Microsoft Excel
®
spreadsheet on the Remote Automation
Solutions SupportNet
™
website. Access
www.EmersonProcess.com/Remote/Support/Support_login.html
and look for
FB107_Power_Wksht.xls
under
Downloads.
Download the spreadsheet to calculate—and manage—variations
on your particular power requirements.
