Adjustment and control

DALI interface	Apply the DALI signal between DA+ and DA−. This is the primary-side DALI interface shown in the catalog.

Temperature and operating conditions

Working case temperature	Tcase −40 to +85°C; maximum case temperature +85°C. Case temperature is not ambient temperature.
Ambient-temperature/load curve	Horizontal mounting: 100% load through +50°C at 110 VAC, or +60°C at 230 VAC; derate along the applicable curve to 60% load at +70°C. The ambient curve ends there. Maintain the case-temperature limit simultaneously.
Case-temperature/load curve	The horizontal-mounting Tcase curve shows 100% load from −40°C through +85°C, then ends. This does not override ambient or low-input derating.
Working humidity	20–95% RH, non-condensing
Storage conditions	−40 to +80°C; 10–95% RH
Altitude derating	Above 2000 m (6500 ft), reduce ambient-temperature allowance by 3.5°C per additional 1000 m for this fanless driver.
Vibration	10–500 Hz; 5 G; 12 minutes per cycle; 72 minutes along each X, Y and Z axis.
Specification and performance-plot conditions	Unless otherwise stated, specifications are measured at 230 VAC input, rated current and 25°C ambient. PF plots use Tcase 75°C; THD and efficiency plots illustrate the 1050 mA model at that case temperature and do not replace the specific model ratings.

Installation safety	Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself.
Ventilation and mounting	Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements.
System wiring and protection	Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system.
Environmental and load limits	Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person.
Connection seals and support	If waterproof connectors are fitted, secure their connections to prevent water entry. Verify the mounting structure and luminaire strength; use safety cables for bay-light applications.
Protective-earth installation	Connect the fitted FG/PE conductor to PE according to this Class I model’s wiring diagram.
DALI installation	This DA version uses the primary-side DALI interface identified in the current catalog. Apply the appropriate DALI signal between DA+ and DA− and follow its dedicated control wiring; do not substitute the B/AB analog-dimming connection. Verify the controller and network compatibility for this interface.
