Electro Industries Nexus 1500+ Power Quality Meter with Phasor Measurement Unit User Guide

Nexus® 1500+ Meter Quickstart Guide

CAUTION! Installation of the Nexus® 1500+ meter must be performed only by qualified personnel who follow standard safety precautions during all procedures. That personnel should have appropriate training and experience with high voltage devices. Appropriate safety gloves, safety glasses, and protective clothing are recommended.
During normal operation of the Nexus® meter, dangerous voltages flow through many parts of the unit, including Terminals and any connected CTs (Current Transformers)  and PTs (Potential Transformers), all I/O Modules and their circuits. All Primary and Secondary circuits can, at times, produce lethal voltages and currents. Avoid contact with any current-carrying surfaces. Do not use the meter or any I/O device for primary protection or in an energy- limiting capacity. The meter can only be used as secondary protection.

IMPORTANT! Refer to your meter’s Installation and Operation Manual for additional safety warnings before performing installation, wiring, or maintenance of your meter. See the link to the manual, below.
NOTE: This Quickstart Guide gives basic installation, wiring, and programming instructions. For additional meter operation and programming information, refer to your meter’s Installation and Operation Manual and the Communicator PQA TM, MeterManagerPQA TM, and EnergyPQA.com Software User manual on EIG’s website:

  You can reach Technical Support from 8 a.m. to 8 p.m. EST, Monday-Friday, at 516-334-0870.

Mechanical Installation

1. Slide the meter into the panel’s cut-out. (See the diagram shown below. You can use either an octagonal or a rectangular cut-out.)
NOTE : You can also mount the meter vertically.

2. From the back of the panel, slide the 4 Mounting Brackets into the grooves on the top and bottom of the meter housing – 2 fit on the top, and 2 fit on the bottom.
3. Snap the Mounting Brackets into place.
4. Secure the meter to the panel with a lock washer and a #8 screw in each of the 4 mounting brackets.
5. Tighten the screws with a #2 Philips screwdriver. Do not over-tighten – maximum torque is 3.5 Lb-In.

Power Supply Connections

Wire gauge: 12-18 AWG for either solid or stranded wire Torque: 3.5 Lb-In
The branch circuit protection size should be 15 A. The Nexus® 1500+ meter requires a separate power source. There are three control power options: 115AC, D2 high-voltage, and D low-voltage.
CAUTION! The power supply voltage and connections vary depending on the power supply Option being used. CAREFULLY follow the instructions and drawings for proper wiring.

115AC/D2 Power Supply Connection

For all three power supply options, add a properly voltage-rated, 4 A, time- delayed (slow blow) fuse in the power supply feed, for example, UL approved Littelfuse® part number FLQ4. For the 115AC and D2 Option power supplies:

1.  Connect the line supply wire to the L+ terminal.
2.  Connect the neutral supply wire to the N(-) terminal.
3. Connect earth ground to the PE GND terminal.

For the D Option power supply:

1. Connect the negative voltage to the V(-) terminal.
2. Connect the positive voltage to the V(+) terminal.
3. Connect earth ground to the PE GND terminal.

Programming the Nexus® 1500+ Meter Using the USB Virtual Com Port  Connecting your PC to the Meter
1. Attach a USB cable from your PC’s USB port to the meter’s front panel USB port. The meter’s USB port uses a USB Type B plug.2. Windows® 7 and above operating systems install the USB driver and display the screen shown on the right. Make note of the Com port being used.
