This document is the manual for the 3 phase max 65A per phase Energy Meter.
The Energy Meter can be used to:
The meter is connected to the Color Control GX. There are two options in its wiring:
When used to measure a PV Inverter, terminals 1, 2 and 3 should face the PV inverter to ensure correct direction of current and power.
In this diagram, a single meter is used to both measure the grid and a single phase PV Inverter.
On the CCGX go to the grid meter in the Wired AC sensor settings. Make sure 'Phase type' is set to 'Single phase' and 'PV inverter on phase 2' is enabled.
Connect the Zigbee to USB converter to the CCGX using the supplied USB cable. A few seconds after connecting, the active LED should be on and the TX/RX LED should be blinking (the converter takes its power from the CCGX, so the CCGX needs to be switched on as well).
Connect the Zigbee to RS485 converter to the ET340 energy meter:
|Zigbee Converter||Energy meter|
Make sure only one Zigbee device is powered up right now: the Zigbee to USB converter connected to the CCGX. Power down all others. If you don't do this, the Zigbee to RS485 converter may be connected permanently to another Zigbee device.
Connect the 12V DC power supply to the Zigbee to RS485 converter. When the power is switched on, check the LEDs again.
Please note that there is a new zigbee converter available now, that is -not- backwards compatible with the old converters. If you have a non compatible set, please ask your supplier for a correct version.
ASS300400100 - Zigbee to RS485 converter partnumber: DRF2619C
ASS300400100 - Zigbee to USB converter partnumber: DRF2618A
ASS300420100 - Zigbee to RS485 converter partnumber: DRF2659C

for the new type Zigbee converters, Venus OS v2.54 is the minimum required software version
Connect the Energy Meter to the CCGX using the USB to RS485 cable. The RS485 to USB interface cable between the CCGX and the Energy Meter can be extended up to 100 meters; make sure that the extensions of the Data+ (orange) and Data- (yellow) wires form a twisted pair.
|RS485 Converter||Energy meter|
|Yellow (Data-)||Terminal 9|
|Orange (Data+)||Terminal 8|
|Black (GND)||Terminal 10|
The red, green and brown wire coming out of the USB to RS485 cable are not used.
After proper connection and powering up, the meter will be visible on the CCGX in the Settings → Energy Meters menu:
The menu lists every meter found. And in the gray box at the right side it shows the configured function.
After selecting a meter, see its detailed settings:
To connect multiple Energy Meters, wire each meter to a separate RS485-USB converter. Which are then each plugged into a separate USB socket on the CCGX.
Connecting multiple ET340 meters to the same RS485-USB cable is not possible: the ET340 meter has no display and its Modbus address can therefor not be changed.
