Size the opening from the unit itself. The frame has no fixing holes, so it is normally bonded or clamped in place; check the method against your enclosure design.\u003c\/p\u003e\n\u003cp\u003eThe IP65 protection applies to the front of the driver only, and only when it is built into a sealed enclosure; the rear is open to the enclosure. Mount on a flat panel with a continuous seal around the frame and protect the rear from water and dust; bonding the driver in and fitting a front cover or grille may be needed to complete the protection. Run the leads so that water cannot track along them into the enclosure. Operating temperature range −25 to 70 °C.\u003c\/p\u003e\n\u003cp\u003eSolder to the solder lugs, observe polarity and keep the leads clear of the moving parts. Use a suitable iron and keep the soldering time short so that heat is not conducted into the driver.
