4. Setup
Follow these steps to set up your KEMOT PROsinus-500 URZ3408 inverter:
- Unpack the Device: Carefully remove the inverter from its packaging and inspect it for any signs of damage. Ensure all components are present.
- Connect the Battery:
- Ensure the inverter is turned OFF.
- Connect the red battery cable to the positive (+) terminal of a 12V DC external battery.
- Connect the black battery cable to the negative (-) terminal of the 12V DC external battery.
- Tighten all connections securely. A small spark may occur during the initial connection; this is normal as internal capacitors charge.
- Connect to AC Input: Plug the inverter's AC input cable into a standard 230V AC wall outlet.
- Connect Loads: Plug your appliances (e.g., central heating pump, TV, refrigerator) into the AC output sockets on the rear of the inverter. Ensure the total power consumption does not exceed 300W.
5. Operating Instructions
5.1. Powering On/Off
- To Power On: Press the ON/OFF button on the front panel. The LED display will illuminate, indicating the device is active.
- To Power Off: Press the ON/OFF button again. The display will turn off.
5.2. Understanding the LED Display
The LED display provides critical information about the inverter's status:
- Input Voltage (V): Shows the incoming AC voltage from the mains.
- Output Voltage (V): Displays the 230V AC output voltage supplied to your appliances.
- Frequency (Hz): Indicates the output frequency, typically 50Hz or 60Hz.
- Battery Level: A bar graph shows the current charge level of the connected external battery.
- Status Indicators: Icons for AC input, battery charging, AC output, and various warning/error conditions (e.g., overload, overheat, low battery).
5.3. Modes of Operation
The KEMOT PROsinus-500 URZ3408 operates in three primary modes:
- Backup Power Supply with Charging Function: When connected to both AC mains and a battery, the device charges the battery. In case of a power outage, it automatically switches to inverter mode, converting 12V DC from the battery to 230V AC for connected appliances. The transfer time is typically less than 4 milliseconds.
- Rectifier (Charger): If only connected to AC mains and a battery, the device will charge the external battery.
- Inverter: If only connected to a battery (no AC mains input), the device will convert 12V DC from the battery to 230V AC to power connected appliances.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter:
- Cleaning: Keep the inverter clean and free from dust. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure that the ventilation openings are not blocked to allow proper airflow and prevent overheating.
- Battery Check: Periodically inspect battery connections for tightness and corrosion. Clean terminals if necessary.
- Storage: If storing the inverter for an extended period, disconnect it from all power sources and store it in a dry, cool place. Ensure the battery is fully charged before storage and recharged periodically to prevent deep discharge.
