3. Setup

3.1 Placement

Place the inverter in a well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure there is sufficient space around the unit for proper airflow, especially around the cooling fan on the rear panel.

3.2 Connecting the External Battery

1. Ensure the inverter is turned off and disconnected from the mains power.
2. Connect the red cable from the inverter to the positive (+) terminal of a 12V DC external battery.
3. Connect the black cable from the inverter to the negative (-) terminal of the 12V DC external battery.
4. Ensure all connections are secure and tight to prevent arcing or poor contact.

3.3 Connecting to Mains Power

Plug the inverter's 230V AC input cable into a standard wall outlet. This will allow the inverter to charge the external battery and provide pass-through power to connected devices when mains power is available.

3.4 Connecting Devices to the Inverter

Plug your appliances (e.g., central heating pump, TV, refrigerator) into the 230V/50Hz output sockets on the rear panel of the inverter. Ensure the total power consumption of all connected devices does not exceed the inverter's rated power of 700W.

Figure 4: Inverter Connection Diagram
This diagram illustrates how the KEMOT PROsinus-700 URZ3406B inverter connects to an external 12V battery and a 230V AC mains input, then provides pure sine wave power to various household appliances such as a grinder, television, refrigerator, and a pellet stove.

4. Operation

4.1 Powering On/Off

1. To Power On: Press the 'Mains On' switch to connect the inverter to the mains power. Then, press the 'Output/Inverter On/Off' button to activate the output.
2. To Power Off: First, press the 'Output/Inverter On/Off' button to disable the output. Then, press the 'Mains Off' switch to disconnect from mains power.

4.2 Operating Modes

• Emergency Power Supply with Charging Function: When connected to mains power and an external battery, the inverter charges the battery and provides 230V AC to connected devices. In case of a power outage, it automatically switches to battery power (inverter mode) with a transfer time of less than 4ms.
• Rectifier (Battery Charger): When only connected to mains power and an external battery, the unit functions as a battery charger, replenishing the external battery.
• Inverter: When only connected to an external 12V DC battery (no mains power), the unit converts the DC power to 230V AC pure sine wave power for connected devices.

4.3 LED Display

The front panel LED display provides critical information about the inverter's status, including input/output voltage, battery charge level, and operational mode indicators. Refer to the display for real-time monitoring.

5. Maintenance

To ensure optimal performance and longevity of your KEMOT PROsinus-700 URZ3406B inverter, follow these maintenance guidelines:

• Cleaning: Regularly clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the cooling fan and vents are free from dust and debris to maintain proper airflow.
• Battery Check: Periodically inspect the external battery connections for corrosion or looseness. Ensure the battery is kept charged, especially if the inverter is not in constant use.
• Environmental Conditions: Operate the inverter within the specified temperature (0 to 40 °C) and humidity (10 - 90 %) ranges. Avoid exposing the unit to extreme conditions.
• Storage: If storing the inverter for an extended period, disconnect it from both mains power and the external battery. Store it in a cool, dry place.

6. Troubleshooting

The KEMOT PROsinus-700 URZ3406B inverter is equipped with several protection features. If the unit is not functioning as expected, consider the following:

• No Output Power: Check if the 'Output/Inverter On/Off' button is pressed. Verify that the external battery is properly connected and sufficiently charged. Ensure the mains power cable is securely plugged in if operating in emergency power supply mode.
• Overload Protection: If the total power consumption of connected devices exceeds 700W, the inverter's overload protection will activate. Disconnect some devices and restart the inverter.
• Short-Circuit Protection: In case of a short circuit in the connected load, the inverter will shut down. Identify and resolve the short circuit before restarting.
• Overvoltage/Undervoltage Protection: The inverter will protect itself and connected devices if the input or battery voltage is outside the safe operating range. Check the mains power supply and the external battery's condition.
• Overheating Protection: If the internal temperature of the inverter becomes too high, it will shut down. Ensure proper ventilation and clear any obstructions from the cooling fan. Allow the unit to cool down before restarting.
• Circuit Breaker Tripped: Check the circuit breaker button on the rear panel. If it has popped out, press it back in to reset.

If issues persist after performing these checks, contact customer support or a qualified technician.
