Important Notes on Wiring
Wiring should be done by a licensed electrician. Be sure to use
appropriate CTs, and never mix CT types on the same device.
The wrong CT can cause severe damage to equipment.
For the SNAP-AIPM-3V module, suitable CTs with a 0.333 VAC
secondary are available from Opto 22. See form #1938, the
Split-Core Current Transformers Data
information.

*Inputs on older modules were 0–250 V and for SNAP-AIPM-3, 0–10 A. Before wiring or scaling, check printed information on the
module to make sure you are using the correct voltage and current. Contact Opto 22 Product Support with any questions.

SNAP-AIPM-3
IMPORTANT—Voltage change: Older SNAP-AIPM-3 and
SNAP-AIPM-3V modules (manufactured before April 2011)
were designed with an input range of 0–250 volts (not 0–300
V) for points 0, 4, and 8. Older SNAP-AIPM-3 modules used 0–
10 A (not 0–5). Before wiring or scaling, check the printed
information on the module to make sure you are using the
correct voltage and current. Older modules can be exchanged
for newer ones; contact Product Support for information.
