Kaman 8000 Enclosures - Manual (Page 21)

If you have an MCD 8000 (for other 1/8 DIN panel meter configurations you will need to see
the specific manual on the meter for changing the input voltage) 110VAC or 220VAC is
selectable using a switch on the indicators main circuit board. Check the instruments tag for
the voltage range set at the factory. If you are changing the input voltage to the unit you will
need to set this switch appropriately. To change the input voltage on the MCD 8000 display
module perform the following steps:
Warning: When you change the input voltage on the rear panel
you must also change the MCD 8000 input voltage
or you may damage the unit.
Warning: The integral power supply in racks utilize high voltage
(120 or 240VAC). Unplug the unit before servicing.
a Remove the MCD-8000 unscrew the 4 screws holding the unit in the
chassis. You will need to very carefully pull this out of the enclosure to
get at the voltage selector switch. Be careful not to pull out any of the
wires attached to the terminal block of the MCD 8000.
b Remove the input selector knob and face plate and spread the black box
to remove the PC board. There is a plastic tab on the bottom side that
holds the PC board in place. Spreading the box slightly will allow the PC
board to slip over the top.
c
On the main display board set the voltage switch for the appropriate
input voltage and replace the unit. See fig. 11 for a top view of the main
display board.
d Reinstall the display module in the unit.
