Important installation notes

Connect only an LED load designed for a constant 24 V DC voltage. Allow a sufficient safety margin in the power rating and verify the polarity before commissioning.

Fixed connections on the 230 V AC side must be made by a qualified electrician. Always check the product’s nameplate and the manufacturer’s installation instructions before making any connections.
