3.2 Power Requirements
The LC-4C and (optional) LC-22C instruments are operated with either 100, 120, 220, or
240 V AC and 50 or 60 Hz power, but the correct voltage must be selected at the cord con-
nector before use. Maximum power consumption is less than 120 watts. The units should
be shipped with the voltage option already matched to the destination, but double check
the settings to be sure they match the power requirements of your laboratory.
Figure 3.5.
Power selection on the LC-4C.
Should the power option need to be changed, unplug the line cord and slide the plastic
window to the left (as shown in Figure 3.5). The orientation of the small circuit board now
exposed in this socket determines the voltage option. If the voltage labeled on the outer
edge of this board is incorrect, pull out the board and turn it (either by rotation or inver-
sion) so that the desired voltage is readable. Reinsert the board and push the fuse holder
back into the cavity. Also check Table 3.2 to see that the fuse is the proper rating.
