2.4.1.4.3 Dual Panel Mode II (Mains-I/II = 1P3W Direct Connection)
The
1-Phase 3-Wire (1P3W)
may only be used with
Dual Panel Mode II
where Mains-I and Mains-II (if
used) may be wired in 1P3W mode as illustrated below.

Dual Panel Mode II (Mains-I/II = 1P3W Direct Connection)
Notes:
1)
Please consult the
Serial Number Label
to ensure that the voltage to be measured is less than or equal to the meter’s rated
Voltage Input specification.
2)
All spare Voltage and Current terminals that are not used should be connected to ground.
2.4.1.5 Custom Panel Mode
The Custom Panel Mode allows the users to freely pair any Branch Input (A, B, C or D) with any Mains
Input (Mains-I/II) using any Wiring Mode (Wye, Delta or 1P3W) with complete flexibility based on the
actual PDU installation, without being restricted by the default Single and Dual Panel Modes that are
supported by the PMC-592. Please refer to the Wiring Diagrams in Sections 2.4.1.1, 2.4.1.2, 2.4.1.3 and
2.4.1.4 for more information on how to connect the PMC-592 in Wye, Delta or 1P3W wiring modes.
2.4.2 Wiring for 5A/10A CT Strip with External CTs
The PMC-592 has been designed for Data Center’s PDU monitoring where the Branch Circuits are
normally under 100A (using the 100A CT Strips or 100A SCCTs). However, for applications such as LV
Distribution Board and Load Center monitoring where the Branch Circuits’ Loading may be higher than
100A. The PMC-592 can be equipped with 5A/10A (5A nominal with 100% over-range) CT Strips to
