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. Those 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, includ-
ing: 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

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
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.
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
