1.
MAINFRAME ASSEMBLY (P/N 126000)
The 3060-MS unit. The mainframe assembly contains the main cabinet
components, input transformer and input and output power contactors.
2.
POWER SUPPLY PANEL ASSEMBLY (P/N 126100)
A ±200 VDC power supply for the inverter assemblies. This assembly is not
a replaceable piece, but individual components such as fuses, filter
capacitors and rectifier diodes are field replaceable.
3.
DISCHARGE PCB ASSEMBLY (P/N 126075)
This PCB assembly contains a soldi-state switch which is active during
shutdown sequences to load the high voltage DC supply so that the DC
voltages are discharged to safe levels, less than 48 VDC. This board also
contains signal conditioning circuits that scale down high voltages to low
voltages which are required for the control and display PCB's.
[With the CE Option. a High Voltage DC blocking PCB Assembly (P/N
126370) is mounted with the Discharge PCB Assembly.]
