Model: EV1000

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

• Necessary hardware (not included):
  • EG4xxx or newer eGauge meter
  • eGauge Sensor Hub (ESH044)
• Read the EV1000 Manual 
• Configuration required: Software configuration is necessary in addition to physical installation. Valid login credentials and familiarity with basic eGauge configuration is needed.

Important Installation Notes

• Signal input: 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.
• Only use straight-through RJ11 cables to connect powered sensors to the Sensor Hub. See this article for more information on verifying the correct RJ-11 wiring. 
• 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, RJ11 cables should be straight-through cables, with the same color order on both ends. RJ-45 cable should be wired to T-568B as shown on the Sensor Hub.

Instructions

Before beginning, check that you have all of the included parts:

Step 1: Mount the Sensor Hub to a DIN rail (35mm top-hat)  and connect the EV1000 to a free port on the Sensor hub using the included RJ-11 cable . Be sure to adjust the selector switch on the Sensor hub port to the left and plug the breakout cable2-pin connector with the same color into an available sensor port on your eGauge. See: Sensor Hub Installation for more details.

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.

In other words, voltage readings from an EV1000 sensors are used the same way the AC line voltages are used in a typical installation.
