WARNING: If the supplied current transducer is placed around a wire carrying
AC current, then extremely high voltages can develop on the output leads of
the current transducer, with severe risk of electrocution. For safety, keep the
output leads of the current transducer(s) shorted or tied together until they are
connected to the proper terminals on the ACM100.
WARNING: User supplied voltage sense cables must be 18 gauge or larger,
have insulation rated to 600V, and must have the conductor connected to the
hot lead of the AC power source protected by a fuse rated at 3A or less (the
current consumed by the voltage sense circuit on the ACM100 is negligible, at
less than 10mA).
Before attempting to connect the ACM100 to the AC source, determine the type of system you
will be monitoring. The ACM100 supports the connection and monitoring of four different system
types; 1) single-phase single line system (Section 2.4.2.1), 2) single-phase dual line system
(Section 2.4.2.2), 3) three-phase wye connected system (Section 2.4.2.3), or 4) three-phase
delta connected system (Section 2.4.2.4).
2.4.2.1 Single-Phase (Phase A) Connection
Please refer to Figure 3 for connecting the ACM100 to a single phase, single line system.

Use the following instructions when you are connecting the ACM100 to a single-phase circuit
connected via one (hot) phase wire and one neutral wire. You will need to install one current
transducer and one voltage sense cable.
Step 1: De-energize the AC Source.
