Connection of EMM to CT’s
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
The high voltage side of the EMM has a hinged cover, which
must be opened. First, remove the two installation screws
(Figure 61), then ip the cover open. The EMM uses an open
style hinge, so it may be easier to completely remove the
hinged door while installing conductors.
The CT’s have built-in output conductors, which must be
connected to the EMM. Each black conductor must be
connected to an EMM terminal labeled, “CT”, while each white
conductor must be connected to the corresponding terminal
labeled, “A”, “B”, or “C”. The two conductors from each CT
must be connected to the same terminal set, i.e. – “CT” and
“A”, “CT” and “B”, or “CT” and “C”. For each CT, the white wire
must go to terminal labeled ‘CT’ and the black wire must go to
the associated lettered terminal (Figure 62).

Installing CT’s
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
Current Transformers (CT’s) are split-core type, to make
installation easier. Snap split-core CT connected to EMM
terminal CT_A on phase L1, snap split-core CT connected
to EMM terminal CT_B on phase L2, and snap split-core CT
connected to EMM terminal CT_C on phase L3 (Figure 63).
Ensure that the “Load” indicator on the CT is oriented correctly.

Connection of EMM to Line Voltage
(Not on Gateway-on-the-Go, IE Express, or
WMC kits)
The EMM is connected to Line Voltage through the Fuse Block
pre-installed on the mounting bracket. Using the provided 6”
wiring harness, connect the “VinA” (Tan), “VinB” (Orange), and
“VinC” (Violet) terminals on the EMM to the “Load” terminals on
the Fuse Block (Figure 64).
