Replacement
WARNING: Removing right side cover exposes extremely dangerous voltages on Capacitor/Power
module. Charges on capacitors can remain at lethal levels long after you unplug system
from AC line. Unplug Workstation from AC line, and discharge capacitors in
accordance with following instructions before touching any circuitry.
You must remove the right side cover before you can remove the rear cover, left side cover, or front leg cover. Follow these
steps to remove the right side cover:
1. Make certain Workstation’s AC power plug is disconnected from AC outlet.
2. Turn off battery breaker.
3. Remove front cover as described in previous screen.
4. Remove and retain three screws that secure front edge of right side cover to generator.
5. Slowly move right side cover forward over Interconnect Cable and High Voltage Cable toward the C. Move cover far enough
forward to give unrestricted access to component you wish to service.
5. Using great care to avoid electric shock, use a VOM to check across capacitor bus bars for residual charge on high energy
capacitors. If any charge is present, connect a 300k, half-watt resistor across capacitor bus bars to discharge capacitors.
