Three-Phase Wiring to SNAP-AIPM-3 Module
NOTE: This wiring method is less expensive than the one on
page 13
CAUTION: Be very careful when connecting input channels.
Do not connect line voltage to the current input
channel; such a connection will result in severe damage to
the module. This damage is not covered by warranty. Use a
current transformer instead.
Using this wiring, after you scale the module, the following measurements are available.
All measurements are synchronously updated every second:
IMPORTANT—Voltage change: Older SNAP-AIPM-3 modules used 0–250 volts and 0–10
amps. Before wiring or scaling, check the printed information on the module to make sure
you are using the correct voltage and current.
• Volts, phase A to phase C
• Volts, phase B to phase C
but does not provide as much information.
• 3-phase sum of 1 sec.—signed energy (watt seconds)
• 3-phase sum of 1 sec.—unsigned energy (watt secs)
SNAP Power Monitoring Modules
CAUTION: Use caution when selecting wire gauges for your
application. Use conservative wire gauges with proper volt-
age ratings.
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.
CAUTION: The SNAP-AIPM-3
module does not contain a fuse.
Protect the system by adding a
fuse.
