Installation Guidelines

• Mounting: Ensure the unit is installed in a vertical position within an IP20-rated enclosure to maintain thermal integrity.
• Ventilation: Maintain adequate clearance above and below the inverter to facilitate airflow as per the cooling requirements for the 3 kW rating.
• Environmental: Ensure the ambient temperature remains within the specified range of -10 degC to +50 degC.
• Grounding: Use the designated grounding terminal to connect the inverter chassis to the common protective earth (PE) point to mitigate EMI.
• Cable Routing: Separate power and control signal cables to minimize electromagnetic interference.
