Changing the Internal Voltage Selector
The 6176 can operate at 115V or 230V. To change the internal voltage selector, wait five minutes after
power down, then unplug the AC power cord from the rear chassis and remove the top cover.
As shown in the photograph below, there is a connector that can be plugged into one location or
another to configure the unit for 115V or 230V operation. (This photograph shows the unit configured
for 115V operation.) The connector is part of the wiring that comes from the power transformer located
at rear center of the 6176, and it can be identified by its wire colors: Black, Blue, White, and Orange.
Move the connector to location H8 for 230V operation or location H6 for 115V operation. NOTE: When
changing operating voltage, the fuse value must be changed as well. Make sure the 6176 is properly
set for the voltage in your area before applying AC power to the unit! Failure to do so may damage
the unit.

Changing Fuses
The AC power fuse is located in the AC power connector block. Remove the power cord before
checking or changing the fuse.
A 400 mA time delay (slow blow) fuse is required for operation at 115 V.
A 200 mA time delay (slow blow) fuse is required for operation at 230 V.
 Never substitute different fuses other than those specified here!
