③ Push the shell upward and take out the circuit board.
④ Take out the small SIM card and insert it into the card slot correctly.
⑤ After installing successfully, reinstall the product shell.
Step2: Install the silicone pad
Tear off the silicone pad's adhesive and stick the silicone pad to the DB9
terminal of the EPEVER RTU 4G A.
Step3: Install the antenna
Connect the 4G antenna to the antenna port of the EPEVER RTU 4G A.
Caution: As a wireless terminal, keep the antenna away from the human body as far
as possible during the operation process.
Step4: Connect the device
Take the connection with the solar controller as an example.
Connect the DB9 connector of the RS485 communication cable to the
EPEVER RTU 4G A, then connect the ends of the RS485 communication
cable to the master LORA module and the battery separately.
※Thanks for selecting the EPEVER RTU 4G A solar wireless collector.

Note: The EPEVER RTU 4G A supports 9~48V DC power. While a larger transient
current is needed when the wireless network sends the data, it is suggested to
adopt a DC power of 12V/500mA or above.
Note: If the EPEVER RTU 4G A is connected with the inverter or inverter/charger.
Connect the DB9 connector of the RS485 communication cable to the EPEVER
RTU 4G A. Then connect the ends of the RS485 communication cable to the
battery and the device COM port. The master LORA module is no longer needed.

8. Troubleshooting
Faults
Solutions
LED indicators are OFF
1. Check whether to supply power to the EPEVER RTU 4G A.
2. Check whether the power supply's poles are connected inversely. The EPEVER RTU 4G A is equipped with anti-reverse protection. The reverse
connection does not cause fatal damage. However, it affects the normal use before the correct connection is restored.
The network indicator is ON solid
After power is on, the network indicator is on solid for 60 seconds. If it still cannot flash after 60 seconds, please check:
1. Check whether the SIM card is inserted correctly. 2. Check whether the GPRS service is activated.
The Network indicator is on solid again after running for a while:
1. Check whether the server status is normal. 2. Check whether the SIM card is loose or arrear.
Smoke emits along with a pungent
smell
The connected battery voltage exceeds the rated voltage, causing the internal components to burn out. Don't hesitate to contact the supplier in
time and send it to the manufacturer.
Unregister on the network
1. Check whether the SIM card is inserted correctly. 2. Check whether the SIM card has activated the GPRS service.
3. Check whether the input power is sufficient. Input power should be 12VDC/500mA.
Parameters can't be configured
1. Check whether the connection to the PC is correct. 2. Check whether the serial port selection is correct.
