Installation and load selection
Confirm that the LED modules require 5V DC and that their combined demand remains within the power supply rating under the actual operating conditions. Keep airflow clear. The specification requires an auxiliary aluminum plate of 400 × 400 × 3mm for full-load operation; use the derating curve when assessing operation at elevated temperatures.
This model is specified for 176–264V AC input. Do not select it for a 110V mains installation. Check the exact model on the unit before wiring, and have installation carried out by a qualified person.
