Acrel ADW310 1-Phase Wireless IoT Energy Meter FAQs
ADW310 has its built-in wireless communication module which allow it to realize 4G LTE, WiFi upstream communication without using extra IoT gateways. For the application scenarios when the meters can't be of centralized installation, ADW310 will usually be the best option for monitor 3-phase circuits that were far from each other.
First, check if the wiring of RS485 communication line was loosen or wired incorrectly.(like reversely wiring the A,B terminal).
Next,inspect if the meter’s setting of address, baud rate, check bit was correct by using keypads on the meter.
Normally, only current input wiring via CT and voltage input wiring via direction connection was necessary for ADW310 to realize basic metering function.
Voltage input of ADW310 also serve as the power supply of ADW310 Seires. Be aware the rated/max voltage input range must be within the range of 85~265Vac L-N.
