Name Color Status Instruction Network indicator (LED2) Red On solid Correct power supply Not registered to the network Slowly Successfully registered to the flashing (5s) network Sync. Indicator (LED1) Green Slowly flashing (5s) Successfully registered to the network Power indicator (LED2) Green Turn off after a flashing Correct power supply 4. Parameter Configuration Step1: Connect the DB9 male connector ❸ to the PC through a DB9 to USB adapter. Note: Connect an external power adapter to the DB9 female terminal to supply the EPEVER RTU 4G A. Step2: Insert the SIM card and power on the EPEVER RTU 4G A. For detailed SIM card installation, refer to chapter 6, Installation. Step3: Open the configuration tool on the PC and click the "connect" button to connect the EPEVER RTU 4G A successfully. Step4: Click the "Read" and "Write" buttons to configure the parameter. Step5: After configuring, power on the product again to make the modified parameters take effect. Common configuration parameters: Parameters Configuration Server Info No modifications are recommended APN Different countries have different APN, and please make sure APN firstly. Products will not be connected to the Internet with fault APN.

System Connection EPEVER RTU 4G A can be applied to the following solar street light systems. Through a 2G/3G/4G signal, users can easily monitor the operating status and modify the related parameters on the Cloud platform. Note: The EPEVER RTU 4G A supports 5~18V DC power. While a larger transient current is needed when the wireless network sends the data, it is suggested to adopt a power adapter of DC 5v/500mA or above. 6. Installation Step1: Install the SIM Card ① Purchase a SIM card and activate the GPRS service. ② Undo the three screws from the EPEVER RTU 4G A. 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. ※ Thanks for selecting the EPEVER RTU 4G A solar wireless collector. Please read this manual carefully before using the product. ※ Please keep this manual for future reference. ❶ Antenna port ❸ DB9 male connector★ ❹ Fixing screws Item Terminal Definition 1/2 NC Floating 3 VCC2 Power2 (12V/200mA) 4 GND2 Power GND2 5 GND1 Power GND1 6 NC Floating 7 RS485-A RS485-A 8 RS485-B RS485-B 9 VCC1 Power1 (5V/400mA) Insert the SIM card in the direction ❷ Hole

Caution: As a wireless terminal, keep the antenna away from the human body as far as possible during the operation process. Step4: Connect the controller Connect the terminal to the controller's com. port through a DB9 adapter. 7. Applications According to different applications, the cloud platform provides two networking connection methods: "one-to-one" and "one-to-more." Controllers can be added into the system convenient and flexible by the two methods. Users can remote control or real-time monitor the controller through the cloud platform. One-To-One connection One-To-more connection After adding the device into the Cloud platform successfully, log in to the cloud platform (https://iot.epsolarpv.com), remotely monitor the real-time condition or set the parameters. Note: For new accounts, devices need to be manually added in the EPEVER cloud before monitoring. 8.

Troubleshooting Faults Solutions LED indicator OFF 1. Check whether the power supply is correct. 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 regular use before the correct connection is restored. Network indicator ON solid After power is on, the network indicator is on solid in 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. Network indicator 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 with a pungent smell The actual 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/0.2A or 5VDC/0.2A. Parameters can't be configured 1. Check whether the connection to the PC is correct. 2. Check whether the serial port selection is correct. 10. Dimension Any changes without prior notice! Version number: 3.2
