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.
Data is transmitted using an RS-485 Modbus protocol. Each data acquisition board
requires two addresses, one for each set of two current sensor strips and four
auxiliary inputs. Data is updated roughly every two seconds. As a circuit approaches
the user-defined 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.

quIck Install
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
1. Disconnect and lock out power. Use a properly rated voltage sensing device to
confirm power is off.
2. Mount current sensor strips adjacent to breaker terminations.
3.
Verify that the serial numbers on the CT strips match the serial number
on main circuit board (Data Acquisition Board).
4. Configure communication and addressing parameters using DIP switches.
5. Mount the main acquisition board in the electrical enclosure.
6. Connect 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.
7. Wire RS-485 communications.
8. Connect CTs to the auxiliary inputs and connect them onto the main conductors in
the enclosure (optional).
9. Wire control power and voltage taps (E30A and E30B only).
10. Download the free E3x configuration tool from www.veris.com to commission the
device for operation.
