Safety & Warnings
Normal use of test equipment can expose users to electrical shock hazards, especially when testing in areas with exposed high voltage. An electrical shock with a current of 10 milliamps passing through the heart can be fatal. Voltages as low as 35 volts DC or AC RMS are considered dangerous as they can produce lethal currents under certain conditions. Users should adopt safe work habits to avoid contact with high voltage and to prevent current from passing through the heart in case of accidental contact. Specific safety precautions include:
1. The DC output of the power supply poses little shock risk, but certain test conditions can create high voltage hazards:
a. A “hot chassis” type equipment under test poses a serious shock hazard unless unplugged or isolated with a transformer.
b. If the equipment under test is powered and uses high voltage, the power supply outputs may float to high potentials. Do not float the output more than 100 volts peak relative to ground.
c. Discharge high-voltage capacitors in equipment under test before making connections or tests, as some circuits retain high voltage even when off.
2. Use a polarized 3-wire AC outlet to ensure the power supply is grounded, reducing shock risk.
3. Avoid unnecessary exposure to high voltage. Remove covers only when needed, turn off equipment when making high-voltage connections, and discharge capacitors after removing power.
