Note: For indoor use only.
*BCPM internal circuitry (cables and CTs) are not circuits as dened by UL508A, as they do not extend
beyond the BCPM itself without further safety/re isolation.
The PowerLogic™ BCPME is designed to measure the current, voltage, and
energy consumption of up to 92 circuits (84 branch circuits, two 3-phase mains,
two neutrals), enabling users to monitor two panelboards or an entire data
center PDU with a single product. It increases the board’s current monitoring
capability by combining the functions of two boards into one device. It also
includes Ethernet capability, allowing communication in multiple protocols.
The BCPME consists of a data acquisition module and up to four current sensor
strips, with eight auxiliary inputs. The strips have rows of solid-core CTs and
are mounted on each side of the panel board along the termination points of
each breaker. The conductor passes through the appropriate current sensor
before terminating at the breaker. Each strip transmits the current data to the
data acquisition board. The BCPME measures both current and power for the
mains and branch circuits. The BCPME can easily accommodate different panel
congurations, including any combination of multi-phase breaker positions,
voltage phase mapping, and breaker sizes. To congure the BCPME for
operation, use the Schneider Electric ION Setup conguration software tool.
Get the latest version at https://schneider-electric.box.com/ionsetuplatest.
Data is transmitted via Ethernet with Modbus TCP, BACnet IP, or SNMP
protocol, or via RS-485 with Modbus RTU or BACnet MS/TP protocols. Some
protocols can be used simultaneously, and the Ethernet protocols all support
access by multiple masters. Each data acquisition board requires two Modbus
addresses, one for each set of two current sensor strips and four auxiliary
inputs (two-strip models only require one Modbus address. As a circuit exceeds
the user-dened thresholds, the BCPME activates the event indicators. The
communication interfaces and protocols require some conguration at the time
of installation.

The BCPME provides several types of measurements that give a
comprehensive view of power consumption for every load on the panel:
• Real-time measurements: A live and up-to-date view of present power
levels and the factors that affect them.
• Demand measurements: Averages of values measured over a
specied time interval. The time interval (typically 15 minutes) can
be set from 10 seconds to more than a day. The demand calculation
can be congured to use single intervals or the sliding average of
up to 6 sub-intervals. Demand measurements are useful for tracking
or graphing load levels over time to correlate with total energy
consumption.
• Historic maximum measurements: These measurements store the
largest value recorded for a specic measurement since the last time
they were cleared. They are useful for identifying peak levels critical to
equipment sizing or demand limits in utility agreements.
• Accumulated energy measurements: Ongoing totals of cumulative
energy used since the last time the value was cleared. Energy values
provide the informational basis for billing, cost allocation, carbon
offset, BTU equivalent calculations, and other applications of overall
energy use.

Branch Circuit Power Meter with Ethernet Communication
Introduction
Z206856-0D
04/2020
• Energy snapshots: Energy totals that only change when the demand
intervals are updated. They are samples of the free-running energy
accumulators at the end of each demand interval, as congured by the
user. These provide energy readings that are easily correlated to the
demand values to simplify the tasks of sub-billing and cost allocation.
• Over-threshold Events (previously referred to as Alarms): Provide a
warning of excessively high or low current on each branch and aux
channel. The user can set two high-level and two low-level thresholds,
and a delay time for latching events. Events are reported as both
non-latched events and latched events. Non-latching events are active
while the current exceeds the threshold, but go inactive if the current
returns to a level within the specic thresholds. Latching events
become active when the current exceeds the threshold for a time
period greater than the specied delay and remain active until they
are cleared remotely. Event status can be polled via any protocol. Via
BACnet, Subscribe_COV can be used to generate event notications.
Via SNMP, they drive SNMP event notications.
Advanced Features - The BCPME supports a number of advanced features.
Some are always active, and others are congured manually via Modbus
register 62017, BACnet object AV164, or SNMP MIB variable “spanels/
panel1/p1Conguration/p1Setup/p1UserDenedSettings” (OID .1.3.6.1
.4.1.3833.1.30.1.1.6.3.4.0). For models with 42 channels or more, these
features are congured independently for each panel.
• Logical meter support: The BCPME can be congured to map any set
of 1, 2 or 3 channels that are adjacent in the panel to a logical meter,
referred to in the point map as a logical circuit, that provides accurate
multi-phase measurement totals. Map these logical circuits by writing
the desired logical circuit number into a set of registers/data objects
provided for each branch and aux channel (per panel).
• The channels assigned to each logical circuit must be adjacent in
the panel (usually used for multi-phase breakers), but there are no
limitations on where those adjacent channels are aligned in the panel
(any position where a multi-phase breaker can be installed). This
functionality is always active, but a user selection affects the how the
data can be accessed via Modbus. Measurement data via Modbus
for logical circuits is presented in two ways, arranged either by logical
circuit number (looks more like a collection of individual meters) or by
measurement type (arranged similar to the single-phase data section
of the point map).
• Legacy point map or alternate logical circuit point map: The BCPME
can be congured to select a preferred version of the Modbus
registers in the address range 4000 to 9999. If enabled (default), the
logical circuits by measurement type is active. Otherwise, the legacy
point maps for 2-phase and 3-phase breakers used in BCPM models
with a rmware version earlier than 1.023 is active. The logical circuits
functionality can also be accessed via the “Logical Circuits by Circuit”
section of the point map (address range 10000 to 45000), regardless
of the state of this selection.
• Phase angle measurements: The BCPME measures the phase angle
of every voltage and current input and presents these measurements
(in degrees) in additional data registers/objects. These values are
used to verify that current inputs are assigned to the proper voltage
phases and to help determine how power factor variations are
inuenced by current phase changes vs. harmonic distortion. Phase
angle measurements are instantaneous and always active.
• User CT phase assignment: In the default mode, the BCPME assigns
each channel to the corresponding phase that most 3-phase panels
implement, so that the user does not have worry about it. The user
can opt to replace this self-assignment paradigm with a mode that
6

Z206856-0D
04/2020
Branch Circuit Power Meter with Ethernet Communication
Introduction
allows explicit specication of the phase assignment for each channel.
The explicit assignments set by the user are stored by the BCPME in
non-volatile memory.
• Phase angle reference: The BCPME measures the phase angle of
every current and voltage input. The user can select whether the
phase angles are stated relative to an absolute reference (the phase
angle of voltage input V1) or relative to the voltage phase assigned to
that specic current input channel.
• Demand/snapshot time interval source: The BCPME offers two
mechanisms for driving the demand/snapshot time interval, an interval
timer or an RTC (real-time clock). The legacy mode (default) uses an
interval timer that does not need to be set to an absolute time. When
using the interval timer the demand/snapshot interval can be set from
10 to 32767 seconds (over 9 hours). An alternate mode utilizes an
RTC set to a specic date and time to synchronize the results with a
larger system. The RTC must rst be set in order to run and capture
demand values and energy snapshots. When power is interrupted, the
RTC resets to a default date and time and must be set again in order
to run. When using the RTC, the demand/snapshot interval can be set
from 10 to 3600 seconds (1 hour).

Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Installation
The protective ground connection on the housing should be used
if the device will not be mounted to a suitably grounded surface. Assure
conductivity to the protective ground.
1. Always use a properly rated voltage sensing device to conrm power is off.
2. Determine where you will mount the BCMPE measurement unit. The
preferred location is inside the enclosure of the panelboard being
monitored. If sufcient space is not available there, then mount the unit in
an appropriate enclosure nearby. Decide whether to mount it vertically or
horizontally. The meter is shipped with the brackets placed on the two sides
for vertical mounting. If desired, you can move the brackets from the sides
to the ends of the housing. Loosen the screws on the sides of the BCPME
that hold the brackets in place (do not fully remove the screws from the
housing). Loosen the screws on the two ends of the housing (do not fully
remove the screws from the housing), and set the brackets into their new
positions. Tighten all screws to 25 in-lb (2.8 N-m).

3. Install the branch current sensor strips into the panel. Select one of the four
circuit congurations shown below and arrange the CTs strips accordingly.
For more detailed installation diagrams and help identifying what circuit
conguration setting to use, refer to the appendix titled: Panel Conguration
Diagrams and Selection Matrix. Adjust conguration of the circuit numbers
in the eld during commissioning by writing to Modbus Register 6 (or
the corresponding BACnet object or SNMP variable) or use ION Setup
conguration software. Most of the examples in this graphic show the 21
current sensor strips. The same conguration options are available for the

• While removing or installing panels and covers, assure that
they do not contact an energized bus.
• NEVER bypass external fusing.
• NEVER short the secondary of a potential transformer.
• Before closing covers and doors, carefully inspect the work
area and remove any tools, wire scraps or other objects that
may have been left inside the equipment.
Failure to follow these instructions will result in death or
serious injury.
NOTE: For all steps in this section, when tightening terminals, apply
the correct torque: Aux Inputs: 3.5 to 4.4 in-lb (0.4 to 0.5 N-m); all
other terminals: 4.4 to 5.3 in-lb (0.5 to 0.6 N-m).
1. Wire the (optional) 0.333 V Aux CTs to the BCPME (see Figure 10),
observing local codes regarding bending radius. Refer to the appropriate
CT installation instructions for further information.

In 3-wire (ungrounded) Delta applications, the BCPME supports these
applications with the following caveats:
Control Power for the meter cannot exceed 277 Vac. In applications
where the L-L voltage is 277 Vac or less (e.g. 208 V line-to-line) it can be
connected to two of the phases being monitored without exceeding the
limit. For higher voltages (e.g. 480 V line-to-line), this must be supplied
from a source that is 277 Vac or less. It could be a separate source or
a transformer can be used to step it down from two of the phases being
measured.
All of the CT inputs (both branches and Aux inputs) are neutral-referenced.
One side of each CT is essentially connected directly to the neutral voltage
input. If this is left oating, the solid-core CT strips, split-core CT adapter
boards and all CTs will oat at the same potential (while the panel is
energized). This does not present a risk to the equipment as long as it is
within 300 V of ground, but should be considered from a safety perspective
in the overall application. The BCPME will provide measurements in this
application with the accuracy specied, with the exception of line-to-neutral

voltages, which will be calculated and reported, based on a derived virtual
neutral voltage, even though they are not relevant.
Corner-grounded delta: the BCPME does not support these applications at any
voltage level.
The BCPME supports measurement of all 4-wire Wye, 3-wire split-phase and
2-wire single phase and congurations that operate between 90 and 300 Vac
line-to neutral.

Follow all applicable wiring and termination connection guidelines for the
standard in use. Note that while both the Modbus RTU and BACnet MS/
TP standards identify requirements for RS-485 line polarization/bias and
termination, the value and placement of these resistors varies for each
standard. The BCPME does not implement any RS-485 line polarization/
bias or termination internally. Shield the RS-485 cable using twisted-pair
wire. Use cable that is voltage-rated for the installation. The shield is not
internally connected to Earth Ground. Connect the shield to Earth Ground
somewhere on the RS-485 bus (single point connection only).
6. Connect an Ethernet cable to a local PC. Secure a ferrite lter (included)
around the Ethernet cable to ensure the device meets emission
requirements. Use the PC to congure the gateway (next section of this
document). Note: 100 to 277 Vac must be added to control power inputs to
supply power to the gateway during conguration.
Figure 15 Ethernet port location
7. Once congured, disconnect the local PC. If desired (and the device is
congured for operation on the network), connect the BCPME directly to
the network for ongoing access to the GUI even if primarily using a serial
protocol to access and control the BCPME.
