Lamp and circuit compatibility: check the LED lamp manufacturer's dimmer compatibility and the permitted load range. Do not mix incandescent and LED loads. For two-way switching, use one dimmer with a conventional two-way switch; the manufacturer instructions do not permit dimming from two dimmers on the same circuit.
Follow the manufacturer instructions and verify that the supply is isolated before work. Disconnect the dimmer before high-voltage or insulation-resistance testing.
