8.3.2 LINE VOLTAGE SELECTION AND FUSE REPLACEMENT
The voltage selection is preset at the factory to your requested line input voltage.
However, the following nominal input voltages can be selected: 100, 120, 220,
240. For a 230 volt supply voltage, the 240 volt option should be used. The two
line fuses are IEC T Type (Slow), 4/10 A, 250 VAC. To change the line voltage
or to replace the fuses, refer to Figure 8-1 and follow the steps below.
Figure 8-1 Power Entry Module
WARNING: To avoid electrical shock or personal injury, disconnect the power
cord before opening the cover on the power entry module.
1. Disconnect the power cord from the power entry module.
2. Using a medium flat-tip screwdriver or similar tool, open the cover on the
power module exposing the two fuses and the voltage selection wheel.
3. Insert the tool into the voltage selection slot and remove the wheel from
the module.
4. Select the desired voltage. Replace the wheel back into the module.
5. If fuse replacement is needed, pull out the fuse holders. Check and
replace fuse(s) with the correct type. Replace the fuse holders back into
the module.
6. Close the module cover, making sure the selected voltage shows through
the window.
8.3.3 GROUND LUG
In particularly noisy environments the MDC-360C should be grounded to the
instrument rack, or other good ground, by means of the grounding lug in the rear
panel. (See Figure 8-3).
