Cautions of DC type Din Rail Meter:
1.About AC/DC & Application
(1) AC- Generally speaking alternating current usually means the input voltage , for example 220/230Vac for house appliance, 380Vac.
However DC for industrial field. In a word AC type energy meter is necessary when measuring in such condition.
(2) DC- Comparing with AC type meter, or AC whole current static energy meter, DC type Din Rail Meter was mainly used for direct current
measuring. It also means not for household and it;scarce.
(3) The application of DC din rail meter mainly exist where power storage for example power storage system, power generator, battery
system etc. It was also used for recharging such as EV charging pile.
2.About Function
(1) Measuring- current measuring achieved by shunt sampling which is cost-efficient and of good accuracy.
(2) Communication- RS485 Communication or RS485 & NB-IOT communication optional, which can also serve as DCU -sending data to the icloud.
(3) Tariff-4 tariffs with 8 slots.
3.Cautions
(1)Installation-Experienced electricians or professionals are required to install electricity meters and make sure that you have read this user guide.
In the process of installation, if the cover has obvious damage marks caused by severe impact or fall, please do not install or power up, and contact
with us immediately;Electricity meters can be installed and used directly if they pass the inspection before leaving the factory;The electricity meter
should be installed in the indoor or outdoor electricity meter box.The mounting base shall be fixed on a solid fire-resistant wall, and there shall be
no corrosive gas in the air;Electricity meters should be wired according to the wiring diagram on the terminal.Copper wire or copper wiring connector
are the best ways to access.
(2)Sealing- Plz fasten the sealing bolts or seals after installation in case of tamper events.
(3)If you have further questions while using plz contact us any time.
