Instruction Manual
Introduction
The LED power supply is a dedicated LED driving device that delivers a constant current/voltage or generates an
adjustable current controlled by an external dimmer to LEDs.
Installation
（
1
）
Before commencing any installation or maintenance work, please disconnect the power supply from the utility.
Ensure that it cannot be re-connected inadvertently!
(2)
Keep proper ventilation around the unit and do not stack any object on it. Also a 10-15 cm clearance must
be
kept when the adjacent device is a heat source.
(3)
Mounting orientations other than standard orientation or operate under high ambient temperature
may
increase the internal component temperature and will require a de-rating in output current. Please
refer to
the specification sheet to receive the optimum mounting position and information about the de-rating
curve.
(4)
Current rating of an approved primary /secondary cable should be greater than or equal to that of the
unit.
Please refer to its specification.
(5)
For LED power supplies with waterproof connectors, verify that the linkage between the unit and the lighting
fixture is tight so that water cannot intrude into the system.
