How to use

Install the ballast in accordance with local electrical codes and the fixture manufacturer’s instructions. Ensure mains power is disconnected before beginning installation. Mount the unit in a location that allows adequate ventilation and observe the specified operating temperature range (−20 to 50 °C). Connect input and lamp wiring according to the wiring diagram provided by the lamp and ballast manufacturer, confirm secure connections, then restore power and verify proper lamp ignition and stable operation.

Recommendations

For reliable long-term performance, avoid exposure to temperatures outside the specified range and provide adequate ventilation around the ballast. Use in compatible fixtures designed for single-lamp fluorescent operation and verify wiring polarity and grounding during installation. Periodic visual inspections can help identify wiring deterioration or mechanical damage before they affect operation.
