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

The Nexus® 1500+ Meter is a sophisticated power quality meter designed for comprehensive energy monitoring and analysis. It is intended for installation and operation by qualified personnel who are trained and experienced with high-voltage devices and follow standard safety precautions. The meter is not to be used for primary protection or in an energy-limiting capacity, but rather as secondary protection.

Function Description:

The Nexus® 1500+ Meter provides advanced power quality monitoring, including phasor measurement unit (PMU) capabilities. It is designed to measure and analyze various electrical parameters, offering insights into power quality, energy consumption, and system performance. The meter can be integrated with software like CommunicatorPQA™, MeterManagerPQA™, and EnergyPQA.com™ for detailed data analysis, configuration, and reporting. It supports various wiring configurations, including WYE or DELTA Direct 3 Phase (4-wire and 3-wire) and WYE or DELTA with PTs (4-wire and 3-wire), accommodating different electrical system setups. The device also features multiple communication ports, including USB Serial, RS-485, and optional Ethernet, allowing for flexible connectivity and remote management.

Important Technical Specifications:

• Power Supply: The meter requires a separate power source with three control power options: 115AC, D2 high-voltage, and D low-voltage.
