Warnings and Disclaimers

WARNING: HIGH VOLTAGE! HAZARD OF ELECTRICAL SHOCK: The power
supply you are working on contains capacitors that store high levels of electrical
energy that can be extremely dangerous or deadly even when disconnected
from the power source. Extreme caution must be exercised when modifying the
power supply. By adhering to the following safety precautions, you can minimize
the risks associated with working on power supplies containing high voltage
capacitors. Remember, safety should always be your top priority when dealing with electrical
equipment.
1. Power Off and Disconnect: Prior to working on the power supply,
ensure that it is completely powered off and disconnected from the electrical outlet.
Unplugging the power supply alone is not sufficient, as capacitors may still retain a
dangerous charge.
2. Discharge Capacitors: Before attempting any repair or maintenance procedures, it is
crucial to allow the capacitors to discharge properly to eliminate stored electrical energy.
Failing to discharge capacitors can result in electric shock. Ensure that the power supply
has been unplugged for at least 10 minutes before opening the power supply enclosure.
3. Insulation and Protective Gear: When working with high voltage capacitors, it is
imperative to wear appropriate personal protective equipment (PPE), such as insulating
gloves, safety goggles, and non-conductive footwear. Insulation provides an additional
layer of protection against electric shock and potential accidents.
One Hand Rule: Whenever possible, use the "One Hand Rule" while working with high
4.
voltage capacitors. This involves keeping one hand behind your back or in your pocket,
ensuring that only one hand comes into contact with any part of the circuit. By doing so,
the risk of current passing through your chest or vital organs is reduced in case of
accidental contact.
Proceed with Caution: Even with proper precautions, high voltage capacitors can still
5.
pose risks. Exercise extreme caution and attentiveness during the entire repair process.
Avoid unnecessary distractions and maintain a focused approach to ensure your safety
and the integrity of the repair.
WARNING: Modifying the power supply's internal circuitry will void its warranty. It
is recommended to thoroughly research and evaluate the potential risks and
benefits of modifying the power supply before proceeding.
