How to use

Installation should be performed by a qualified electrician to ensure safety and compliance with local electrical standards. Begin by disconnecting the power supply to the lighting fixture. Mount the ballast securely within the fixture housing using the provided mounting points. Connect the lamp wires according to the wiring diagram printed on the ballast casing, ensuring all connections are tight and properly insulated. Once installed, reconnect the power and verify that all connected fluorescent lamps ignite correctly.

What to consider before purchase

• Verify that the total wattage and number of lamps match the ballast specifications.
• Ensure the physical dimensions fit within your existing light fixture housing.
• Confirm that the operating environment temperature remains within the specified -15 to 50 °C range.

Usage recommendations

For optimal performance and longevity, ensure that the ballast is installed in a well-ventilated area within the fixture to prevent overheating. Always replace all lamps in a multi-lamp circuit simultaneously to maintain uniform light output and prevent premature ballast strain.
