INSTALLATIoN GUIDe

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 conrm power is o.

2. Mount the main acquisition board in the electrical enclosure.

3. Mount adapter boards to either DIN Rail or SNAPTRACK™.

4. Connect adapter boards to the main board via ribbon cable (sold separately).

5. Connect current transducers to the adapter boards.

6. Snap current sensors onto the conductors to be monitored. Note: ensure that

each split-core CT is closed and ﬁrmly seated.

7. Secure wires using strain relief cable ties.

8. Congure communication and addressing parameters using DIP switches.

9. Wire RS-485 communications.

10. Connect CTs to the auxiliary inputs and connect them onto the main conductors in the enclosure (optional).

11. Wire control power and voltage taps (E31A and E31B only).

12. Download the free E3x conguration tool from www.veris.com to commission the device for operation.

oPeratIon

The E31 Series Branch Current Monitor is 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. One E31 can monitor up to two panels.

The E31 consists of a data acquisition board and up to 84 split-core current sensors (50A, 100A, or 200A), with eight auxiliary inputs. Each conductor passes through a current sensor and terminates at the breaker. Each sensor 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 42 current sensors and four auxiliary inputs. Data is updated roughly every two seconds. As a circuit approaches the userdened threshold, the E31 activates the alarm indicators.

The E31A measures both current and power for the mains and branch circuits. The E31B measures both current and power for the mains, and current only in each circuit. The E31C measures current only for the mains and branch circuits.

1. 50-Pin Ribbon Cable Connectors: Ribbon cables attach here for easy

connection of adapter boards to the data acquisition board. The two connectors on the left are for panelboard 1; the two on the right are for panelboard 2.

Note: Connect Adapter Boards A and B to the correct ribbon cable connectors for each panel. The top connec tor is for Adapter Board A, and the bottom connector is for Adapter Board B.

Note: Ribbon Cable is not included with all E31 models. For ribbon cable options, see Recommended Accessories on page 11.

2. Auxiliary Inputs: These 0.333VAC inputs are used for monitoring the main

breaker or other high amperage source. Inputs on the lef t are for panelboard 1; inputs on the right are for panelboard 2.

3. Control (Mains) Power Connection: Easy 2-wire 90-277 VAC 50/60 Hz

connection.

4. Control Power Fuse: 600VAC, 500mA time lag, factory-replaceable.

5. Alive LED: Red/green/amber LEDs. Blink codes are on page 3.

6. Voltage Taps: 1, 2, or 3 phase plus neutral connections. For voltage sensing and

power calculations (no voltage taps on the E31C). Voltage taps are shared by both panels.

7. Communications Address DIP Switch: Each Modbus device must have a unique

address. Switches are binar y weighted. Left-most switch has a value of 1; rightmost switch has a value of 128. Note: switches set the address for panel 1; panel 2 is automatically set to (Panel 1 address + 1). See Conguration section for details.

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 electrical panel and lock it out.

1. Install the acquisition board mounting bracket in the panel using screws and bolts provided Panels can be oriented side-by-side (Figure 1A) or vertically (Figure 1B). A grounding connection is located on the mounting bracket, near the lower right corner. Use this stud to ground the bracket when mounting on a nonconductivesurface.
