Three-Phase Wiring to SNAP-AIPM-3V Module
CAUTION: Be very careful when connecting input channels.
Do not connect line voltage to the current input
channel; such a connection will cause severe damage to
the module. This damage is not covered by warranty. Use a
current transformer instead. Use identical CTs on all phases.
CAUTION: Use caution when selecting wire gauges for your
application. Use conservative wire gauges with proper volt-
age ratings.
Using this wiring, after you scale the module, the following measurements are available.
All measurements are synchronously updated every second:
Suitable current transformers (CTs) for use with the SNAP-AIPM-3V are available from
Opto 22. See form #1938, the

CAUTION: Terminals 2 and 3 share a common connection
inside the module. Make sure you observe polarity when
connecting the second channel. To avoid a potentially
hazardous short circuit, double-check wiring before turning
on the current to be monitored.
