QUICK INSTALL
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Disconnect and lock out power. Use a properly rated
voltage sensing device to confirm the power is off.
1. Mount the current sensor strips adjacent to the breaker terminations.
2. Verify that the serial numbers on the current sensor strips match the
serial number on the data acquisition board.
3. Congure communication and addressing parameters using the DIP switches.
4. Mount the data acquisition board in the electrical enclosure.
5. Connect the current sensor strip cables to the main board, observing the 2-strip or
4-strip setup and their orientation (A or B) within the panel.
6. Wire the RS-485 communications.
7. Connect the CTs to the auxiliary inputs and connect them to the main conductors
in the enclosure (optional).
8. Wire the control power and voltage taps (E30A and E30B only).
9. Download the free E3x conguration tool from www.veris.com to commission the
device for operation.
PRODUCT OVERVIEW
The E30 Series Branch Current Monitor is a device designed to measure the current,
voltage, and energy consumption of up to 92 circuits (84 branch circuits, 2 3-phase
mains, 2 neutrals) on a single board. It increases the board’s current monitoring
capability by combining the functions of two boards into one device.
The E30 consists of a data acquisition board and up to four 21-unit current sensor
strips, with eight auxiliary inputs. The strips 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 user-dened threshold, the E30 activates the alarm indicators.
The E30A measures both current and power for the mains and branch circuits. The
E30B measures both current and power for the mains, and current only in each circuit.
The E30C measures current only for the mains and branch circuits.

3. Verify that the serial numbers printed on the current strip and on the data
acquisition board match. The board and the strip are sold as a calibrated set.
4. Congure communication and addressing parameters using DIP switches. The
E30 requires two addresses, one for each set of two current sensor strips and four
auxiliary inputs. See the Conguration section on page 7 for more information.
5. Install the E30 acquisition board mounting bracket in the panel using screws and
bolts provided (Figure 3). A grounding connection is located on the mounting
bracket, near the lower right corner. Use this stud to ground the bracket when it is
mounted on a nonconductive surface.
6. Check the labels on the current sensor strip and on the data acquisition board
to make sure the serial numbers match. Additionally, the label indicates which
connector to use on the data acquisition board (e.g. connect the strip labeled
“Panel 1A” to the top left connector on the board; Figure 4). When the device is
powered, if the current sensor strips are installed incorrectly, the Alive LED blinks
amber, three times per second. Check the labels and correct the connections.
Figure 4
Serial numbers on bo ard and strips must match.
Connect strips only to the connec tor designated
on the label (e.g. 1A).

CONFIGURATION
1. Communications Conguration: Communications parameters for the E30 series
are eld selectable for your convenience. Please see the Product Diagram section
(page 2) for selector location. The following parameters are congurable:
• Baud Rate: 9600, 19200, 38400
• Parity On or O
• Parity: odd or even
• Wiring: two or four
INSTALLATION GUIDE
3. The E30 uses two logical addresses. Panel 1 uses the base address as set on the DIP
switches, and Panel 2 uses this base address + 1. Address the E30 as any whole
number between and including 1-246. Each unit is equipped with a set of 8 DIP
switches for addressing. See below.

4. To determine an address, simply add the values of any switch that is on.
For example:
LSB
Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32.
(8 + 32 = 40). Therefore, the address for Panel 1 is 40, and the address for Panel 2 is
41.
See the Address Setup section (page 8) for a pictorial listing of the rst 63 switch
positions.

DEFAULT DIP SWITCH SETTINGS
The E30 includes two DIP switches, as shown below. Switches are shown in their
default positions.
2. Address Conguration: Each Modbus device on a single network must have
a unique address. Set the switch block to assign a unique address before the
device is connected to the Modbus RS-485 network. If an address is selected that
conicts with another device, neither device will be able to communicate.

SAFETY
If Veris E30 products are used in installations with circuits higher than the product
ratings, the circuits must be kept segregated per UL508A Sec. 17.5.
Note: 277/480 VAC Wye connected (center grounded) power systems operate
within the 300 VAC line to neutral safety rating of the E3x series, and the
operational voltage limit (single-phase connection) as the line to neutral
voltage is 277 VAC in such power systems. Corner-grounded delta 480 VAC
systems would not qualif y, as the actual line to earth voltage is 480 VAC on
each leg, exceeding the E3x ratings.
Note: E3x internal circuitr y (cables and CTs) are not circuits as dened by
UL508A, as they do not extend beyond the E3x itself without further safety/
re isolation.
UL listed under standard 508 as an “open type device.”
Maximum ambient air temperature for use is 60°C.
The E30 Series must be installed in an appropriate electrical and re enclosure per
local regulations.
Installation categor y: CAT III
For use in a Pollution Degree 2 or better environment only.
A Pollution Degree 2 environment must control conductive pollution and the
possibility of condensation or high humidity. Consideration must be given to the
enclosure, the correct use of ventilation, thermal properties of the equipment and the
relationship with the environment.
If the equipment is used in a manner not specied by the manufacturer, the
protection provided by the device may be impaired.
IEC/EN 61010-1

TROUBLESHOOTING
Problem Solution
Product is not communicating over Modbus daisy chain
RX LED is solid
The main board has a fast ashing amber light
The main board has a slow ashing amber light
The main board has a ashing green light
The main board is a ashing or solid red light
Power factor reading is not as expected
Current reading is not as expected, or reading is on dierent CT
number than expected
Current is reading zero, even when small currents are still owing
through circuit
E3x Cong Tool returns Modbus error on read/write
E30
• Check the unit Modbus address to ensure that each device on the daisy chain has a unique address.
• Check Parity.
• Check the communications wiring.
• Check that the daisy chain is properly terminated.
• Check for reversed polarity on Modbus comms.
• Check for sucient biasing on the Modbus bus. Modbus physical specication calls for 450-650 Ω biasing. This is
usually provided by the master.
• Check that the 1A and 1B CT strips are connected to the left top and left bottom ribbon cable connections; 2A and 2B
must be connected to the right top and right bottom ribbon cable connections (see illustrations in the product install).
• Verify ribbon cable connectors are inserted in the correct orientation.
• If cables are correct, reset main board to re-initialize product.
• Verify serial number on strips matches serial number on main board.
• One or more channels is clipping. This can be caused by a signal greater than 100 A or 277 V L-N, or by a signal with
high THD near the gain stage switching points (1.5 A and 10 A).
• Everything is wired properly and the main board has power.
• Light may be red briey while device powers up.
• If light is red for more the 60 sec. device has encountered a diagnostic event. Contact technical support.
• Verify voltage taps are connected in appropriate phase rotation.
• Verify strip conguration register matches actual strip installation.
• Verify phase rotation of breakers (rmware rev. 1.012 or higher allows for custom rotation if needed).
• Verify strip conguration register matches actual strip installation.
• Verify ribbon cable is fully seated and in the correct orientation.
• The product cuts o at 50 mA, and will set the reporting register to 0 mA for currents near or below this range.
• Verify using the latest release of E3x Cong Tool as older versions may not support all features in current product
rmware. Latest version is available on our website http://www.veris.com/modbus.aspx
