| 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. |
| Weather protection |
This model is IP67 with an adjustment function and must be installed indoors or in a location sheltered from rain outdoors, as required by the installation manual. The IP rating does not permit immersion. |
| Digital-controller installation |
This DA option uses DALI, with the control cable identified as DA+ and DA−. Verify the supplied wiring and compatible controller/network; do not treat these terminals as the analog DIM or timer PROG interface. If standalone dimming conductors smaller than 18 AWG are used, use only SELV controllers or networks and contact MEAN WELL before using FELV control. |
| Auxiliary-output identity |
The A suffix immediately after 650 identifies the auxiliary-output version. Its auxiliary output is 12 V at 200 mA, with AUX+ gray and AUX− black. Keep the auxiliary circuit separate from the LED power and control interfaces and within its stated rating. |
| Input switching |
For the catalog ErP condition, use this driver behind a switch; do not connect it permanently to the mains. |
