Overview
The eGauge High Voltage sensor is used in conjunction with the Sensor Hub and an EG4xxx model meter (Core or Pro) which allows EG4xxx meters to read voltages up to 1,000 VDC or 707 VAC. Follow the guidance in this article to install and configure this sensor for use with the eGauge meter.
Prerequisites
The high voltage inputs to the EV1000 can be connected Line-to-Line or Line-to-Neutral as long as the voltage potential does not exceed 1,000 VDC or 707 VAC. Safety grounds cannot be used for voltage measurements.
- This hardware is compatible with EG4xxx meters. Older models are not supported.
- A Sensor Hub is required.
- It is not advisable to extend the RJ11 leads from the Sensor to Sensor Hub. It is acceptable to use a longer RJ45 cable from the Sensor Hub to the eGauge.
- If RJ11 cable between Sensor and Sensor Hub must be extended, it is advisable to use twisted pair wires, such as a CAT5 cable with RJ11 plugs (most commonly used for DSL modems).
- If terminating own cables, both RJ11 and RJ45 cables should be straight-through cables, with the same color order on both ends.
Instructions
Step 1: Install the Sensor Hub and connect the EV1000 to a free port on the Sensor hub using the included RJ-11 cable . For details please see: How to: Install the Sensor Hub.
Step 2: Connect the EV1000 to a voltage reference no greater than 1000 VDC or 707 VAC. Connection will vary between installation types, consult the correct installation example wiring diagram for details.
Step 3: Configure the sensor in the eGauge settings by scanning it with CTid. EV1000 voltage readings connected to eGauge sensor ports via the Sensor Hub can be used in power calculations as shown below:
In the example above, CTs detecting current are connected to sensor ports 1-3 and EV1000 sensors are connected to sensor ports 4-6 which are used as reference voltages to calculate power.
