Section 13 Servicing–Capacitor Bank Module
WARNING: Even when the laser is off and the AC line cord is disconnected, DC voltages
on various laser components, such as capacitors may exist. This can present a potentially
fatal electrical hazard during service procedures. Proceed with caution
!
Removing the Cap Bank Module
Hazardous voltage. Capacitor bank may contain stored energy. Make
sure capacitors are fully discharged before servicing
1. Turn off and unplug the laser. Check the remaining charge on the cap bank with a DVM.
2. Disconnect the two high voltage wires (red and black) to the blocking diodes of the
IGBT shelf.
3. Disconnect the two signal fibers from the cap bank module.
4. Loosen the two 1/4-20 nuts at the bottom of the cap bank shelf, and then slide the module
a third of the way out of the laser.
5. WARNING: Be careful not to injury yourself when removing and installing the
module—it weighs sixty pounds and should be handled with care.
6. Disconnect the two high voltage wires from the output of the HVPS.
7. Remove the entire module.
8. Reassemble by reversing the previous steps.
9. Recalibrate the High voltage power supply and the high voltage readback as described in
“Calibrating the HVPS” on page 83.
WARNING: Do not attempt to short directly (i.e., with a screwdriver) or a potentially fatal
electrical shock can occur.
Replacing a Cap Bank Fuse
1. Turn off and unplug the laser.
2. Using a shorting stick, discharge each capacitor unto zero volts is reached.
3. Remove the fuse. If the fuse cannot be reached, remove the cap bank module as detailed
in the section above.
4. Install the new fuse, and then reassemble.
