2. Safety Information
Read all instructions and warnings carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, serious injury, or death.
- Installation: Ensure the inverter is installed in a well-ventilated area, away from flammable materials, and protected from direct sunlight and moisture.
- Battery Connection: Always connect the inverter to a 48V DC battery system. Connect the negative (-) cable first, then the positive (+) cable. Ensure all connections are tight and secure to prevent sparking and overheating.
- Grounding: The inverter must be properly grounded. Connect the grounding lug on the inverter to an appropriate earth ground.
- Load Capacity: Do not overload the inverter. Ensure the total wattage of connected appliances does not exceed the inverter's continuous power rating (3000W) or peak surge capacity (6000W).
- Polarity: Never reverse the polarity of the battery connections. This will damage the inverter and void the warranty.
- Maintenance: Regularly inspect cables and connections for wear or damage. Replace fuses only with the specified type and rating.
- Emergency: In case of smoke, unusual odors, or abnormal operation, immediately disconnect the inverter from the battery and AC loads.

4. Setup
Proper installation is crucial for the safe and efficient operation of your inverter. Follow these steps carefully.
4.1 Mounting the Inverter
- Choose a dry, cool, and well-ventilated location.
- Mount the inverter securely using appropriate fasteners. Ensure there is sufficient space around the unit for airflow, especially around the cooling fans.
4.2 DC Input Connection (Battery)
The inverter requires a 48V DC battery system. Use the provided battery cables for connection.
- Ensure the inverter is turned OFF before making any connections.
- Connect the negative (-) battery cable (black) to the negative terminal of your 48V battery bank.
- Connect the other end of the negative (-) cable to the black terminal on the inverter.
- Connect the positive (+) battery cable (red) to the positive terminal of your 48V battery bank.
- Connect the other end of the positive (+) cable to the red terminal on the inverter.
- Tighten all connections securely using the provided hardware (flat washer, lock washer, nut).

4.3 Grounding the Inverter
Connect the grounding screw on the inverter chassis to a reliable earth ground using a suitable gauge wire. This is essential for safety.
4.4 AC Output Connection
The inverter provides two standard US AC outlets and a hardwire terminal block.
- Standard Outlets: For connecting typical household appliances directly.
- Hardwire Terminal Block: For connecting high-power appliances or integrating into a distribution panel. Ensure proper wiring (Live, Ground, Neutral) according to local electrical codes.

5. Operating Instructions
Once properly installed, operating the WZRELB inverter is straightforward.
5.1 Powering On/Off
- Ensure all DC and AC connections are secure.
- Press the ON/OFF switch on the front panel to power on the inverter. The digital display will illuminate, showing the input DC voltage and output AC voltage.
- To power off, press the ON/OFF switch again.
5.2 Connecting AC Loads
- Plug your AC appliances into the standard outlets or connect them to the hardwire terminal block.
- Always check the wattage requirements of your appliances to ensure they do not exceed the inverter's capacity.
5.3 Load Considerations
Different types of loads have varying power demands:
- Resistive Loads: Appliances like heaters, toasters, and incandescent lights draw power consistently. Choose an inverter with continuous power higher than the appliance's rated power.
- Inductive Loads: Appliances with motors or compressors (e.g., refrigerators, air conditioners, power tools) have a high startup (surge) current. For these, choose an inverter whose continuous power is 3-7 times higher than your appliance's rated power to handle the initial surge.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your inverter.
- Cleaning: Keep the inverter clean and free from dust and debris. Use a dry cloth to wipe the exterior. Do not use liquid cleaners.
- Ventilation: Ensure the cooling fans and ventilation openings are not blocked. The intelligent cooling fans activate automatically when the internal temperature rises, helping to dissipate heat.
- Connections: Periodically check all DC and AC connections for tightness. Loose connections can cause overheating and power loss.
- Fuse Replacement: If the inverter stops working due to an overload or short circuit, check the fuses. Replace blown fuses only with spare fuses of the correct type and rating provided with the unit.
