Verify the Switch Passes Self Test Before mounting the switch, verify it is working properly by plugging it into a power source and confirming that it passes self test. The switch does not have a power switch. It is powered on when the power cord is connected to the switch and to a power source. For safety, the power outlet should be located near the switch installation. The switch automatically adjusts to any voltage between 100-240 volts and either 50 or 60 Hz. No voltage range settings are required. If your installation requires a different power cord than the one supplied with the switch, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the switch. 1.
