ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in equipment
damage or equipment damage.
Capacitors can store electrical energy when power is off.
Electrical shock can result if you touch the capacitor terminals
and discharge the stored energy. Exercise extreme caution
when working near capacitors. With power off, discharge
stored energy by shorting across the capacitor terminals with a
15,000
−
ohm, 2
−
watt resistor.
Always check capacitors with power off. Attempting to
troubleshoot a capacitor with power on can be dangerous.
Defective capacitors may explode when power is applied.
Insulating fluid inside is combustible and may ignite, causing
burns.
