Capacitor Discharging Procedure
After disassembling the case as described in
Disassembling the Case (p. 181)
immediately discharge the energy storage capacitor using the capacitor discharge tool as
described in
Using the Capacitor Discharge Tool (p. 178)
located through holes on the interconnect bracket in the rear case.
Using the Capacitor Discharge Tool
To use the capacitor discharge tool:
1.
Place one probe on a discharge point and hold it steady.
2.
Place the other probe on the remaining discharge point and hold both
probes steady.
3.
Observe the neon lamp inside the capacitor discharge tool. If a charge of
approximately 90 volts is present, the neon lamp will light.
4.
Continue holding the probes on the points indicated for at least 30
seconds after the neon lamp is no longer lit.
NOTE:
You may need to disconnect the P51 connector of W20 from the therapy PCB to
gain access to discharge points.
DANGER
SHOCK HAZARD
Lethal voltages may be present even without operator
action. Do not assume the capacitor is uncharged if the neon lamp does not
light! There may still be a charge on the capacitor. Do not touch capacitor
terminals until completing the discharge operation.
