! IMPORTANT !
It is important that all 3300 ACM
installations include communica-
tions wiring. Refer to Section 2.6
for more information.
2.5.6 CONNECTION FOR SINGLE
PHASE SYSTEMS
Wiring for Single Phase systems is performed by connecting
the two voltage phases (each 180 degrees with respect to
each other) to the V1 and V2 inputs of the 3300 ACM, and
the outputs of the two corresponding current transformers
to the I1 input pair and I2 input pair.
This is illustrated in Figure 2.5.6 below. Note that the V3
input and I3 input pair are unused and should all be
grounded. For Single Phase systems, the VOLTS MODE of
the 3300 ACM should be set to SINGLE PHASE.
NOTES: 1. VOLTS MODE = SINGLE PHASE 2. Note the polarity of each CT.
