WARNING
SHOCK HAZARD: The large electrolytic capacitor(s) (blue-cased cylinder(s)) store large amounts of
energy in the form of electric voltage. Even if the power is off, dangerous voltages exist at the capacitor
terminals, on the chopper, and the diode heatsinks. Never discharge the capacitor(s) with a screwdriver or
other implement…explosion, property damage and/or personal injury will result. Wait at least five minutes
after turning the power supply off before touching the chopper or the capacitor(s).
