Risk of Electric Shock
There is a risk of electric shock during replacement of the low voltage power supply.
Use insulating gloves or avoid direct contact with any conducting part of the
power supply, and caution should be exercised during replacement.
The capacitor may take one minute to complete discharge after the AC cable
is unplugged. Also, there is a possibility that the capacitor doesn’t discharge
