Product Identification
Product Overview
The E30E Series panelboard monitoring system 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.
The E30E consists of a data acquisition module and up to four branch 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 E30E measures
both current and power for the mains and branch circuits. The E30E can easily accommodate dierent panel
congurations, including any combination of multi-phase breaker positions, voltage phase mapping, and breaker
sizes. To congure the E30E for operation, download the E3x Conguration Tool and the E3x Commissioning Guide
from www.veris.com.
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 (2-strip models only require one Modbus address). Data is updated roughly
every two seconds. When a circuit exceeds the user-dened thresholds, the E30E activates the alarm indicators. The
communication interfaces and protocols require some conguration at the time of installation.

Power Monitoring
EESeries TM
The E30E 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 aect them.
• Demand measurements: averages of values measured over a specied time interval. The time interval (typically 15
minutes) can be set from 10 seconds to more than a day. The demand calculation can be congured 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 specic 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 oset, BTU equivalent
calculations, and other applications of overall energy use.
• 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 congured 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.
• 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 alarms. Alarms are reported as both non-latched
events and latched events. Non-latching alarms are active while the current exceeds the threshold, but go inactive if
the current returns to a level within the specic thresholds. Latching alarms become active when the current exceeds
the threshold for a time period greater than the specied delay and remain active until they are cleared remotely.
Alarm status can be polled via any protocol. Via BACnet, Subscribe_COV can be used to generate alarm notications.
Via SNMP, alarms drive SNMP event notications.
Advanced Features - The E30E supports a number of of advanced features. Some are always active, and others are congured
manually via Modbus register 62017, BACnet object AV164, or SNMP MIB variable “spanels/panel1/p1Conguration/p1Setup/
p1UserDenedSettings” (OID .1.3.6.1 .4.1.40845.1.30.1.1.6.3.4.0). For models with 42 channels or more, these features are
congured independently for each panel.
• Logical Circuit support: The E30E can be congured to map any set of 1, 2 or 3 channels that are adjacent in the panel
to 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 aects 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 E30E can be congured 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 older E3x models 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 E30E 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 inuenced by current
phase changes vs. harmonic distortion. Phase angle measurements are instantaneous and always active.
• User CT phase assignment: In the default mode, the E30E 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 allows explicit specication of the phase assignment for each channel. The
explicit assignments set by the user are stored by the E30E in non-volatile memory.
• Phase angle reference: The E30E 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 specic current input channel.
• Signed power factor: By default the E30E reports power factor as an unsigned value. The user can set it to report as a
signed value, where the sign indicates whether the current phase angle leads or lags the corresponding voltage phase.

• Demand/snapshot time interval source: The E30E oers 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 specic 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).

Installation Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Disconnect power to the panel before beginning the installation.
1. Locate a surface inside the electrical enclosure to mount the E30E. Decide whether to mount the E30E vertically or horizontally.
The E30E is shipped with the brackets placed for vertical mounting. If mounting horizontally, loosen the screws on the sides
of the E30E that hold the brackets in place (do not fully remove the screws from the E30E housing). Loosen the screws on the
other two sides of the housing (do not fully remove the screws from the E30E housing), and set the brackets into their new
positions. Tighten all screws.
Vertical Mounting Horizontal Mounting
2. Install the current sensor strips into the panel. Arrange the sensor strips in one of the four congurations shown below.
Adjust orientation of the circuit numbers in the eld during commissioning by writing to Modbus Register 6 or use the
free conguration software at www.veris.com. The examples in this graphic show the 21 current sensor strips. The same
conguration options are available for the 18 and 12 current sensor strips.

3. Verify that the serial numbers printed on the current sensor strips and on the E30E match. The board and the strips are sold as a
calibrated set.
4. Install the E30E in the panel (hardware not provided). A grounding connection is located on the housing (see below). Use this
stud to ground the device when it is mounted on a nonconductive surface.

5. Connect the current sensor ribbon cables to the 50-pin connectors on the E30E. The label on the strip indicates which connector
to use on the E30E (e.g. connect the strip labeled “Panel 1A” to the bottom right connector on the board). Orient the cables so
that the plastic key on the E30E connector aligns with the keyhole cutout on the ribbon cable connector, as shown below.

Note: The E30E measures and reports the phase angle of each voltage input and each CT (when there is active current
through the primary of that CT). Use the E3x Conguration Tool to view the phase angles of active circuits to help verify
that those circuits are connected to and mapped to the proper voltage phases. See the E3x Commissioning Guide (www.
veris.com) for instructions on how to download and operate the tool from a PC.
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 Aux input CTs to the E30E. Note: For Veris CTs, X1 is the white lead, X2 is the black lead.

4. Mechanically secure the RS-485 cable where it enters the electrical panel.
5. If using Modbus RTU or BACnet MS/TP protocol, connect a serial cable(s) from the RS-485 loop to the serial connector on the
E30E. Connect all RS-485 devices in a daisy-chain, and properly terminate the chain. Two sets of connections are provided
to simplify daisy-chain connections and enable retention of each wire. Follow all applicable wiring and termination
connection guidelines for the standard in use. Note that while both the 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 E30E does not implement any RS-485 line polarization/bias or termination internally. For the RS-485 cable,
use shielded, twisted-pair wire, such as Belden 1120A, 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).

WARNING: After wiring
the RS-485 cable, remove

be DANGEROUS!
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 congure the gateway (next section of this document).
7. Once congured, disconnect the local PC. If desired (and the device is congured for operation on the network), connect the
E30E directly to the network for ongoing access to the GUI even if primarily using a serial protocol to access and control the
E30E.
