Scaling
If you are using PAC Control, when you configure the points on
SNAP power monitoring modules, you must scale them to
match the CT you use. Scaling must be accurate for the
resulting data to be accurate. The examples starting on
can help you determine the correct values for your CT and
module.
IMPORTANT: For all installations of 85 to 250 VAC, both Actual
and Scaled Volts (point 0 on all modules, plus points 4 and 8
on the SNAP-AIPM-3 and SNAP-AIPM-3V) should remain at
the default of 0–250 VAC.
However, for installations over 250 VAC (such as lighting
systems using 277 volts), you will need to scale these points.
For help, see
with PT” on page 7
PT” on page
than 250 VAC require you to use a step-down potential
transformer.

For the SNAP-AIPM, you see four points. For the SNAP-AIPM-3
(shown above) or the SNAP-AIPM-3V, you see 14. You must
configure each point.
In PAC Control, open your strategy. In the Strategy Tree,
right-click the I/O unit containing the power monitoring
module and choose Configure from the popup menu.
Click the I/O points button. Double-click the module’s
position number on the rack. Click Analog Input and
then choose the module’s part number from the list.
Click OK.
Click the plus sign next to the module to open its points.

Double-click point 0, the voltage input, and give it a
name. If you’re not using a PT, leave the scaling as is. The

Click OK.
Continue to configure each point on the module,
following the calculations in the examples on the next
two pages. (For SNAP-AIPM-3V, see the examples on
