Version 1.A Model IIC-200 Operation Manual 9
The plug on the line cord supplied with the system should be compatible with the
line-voltage outlets in common use in the region to which the system is shipped. If
the line cord plug should prove to be incompatible, a compatible plug should be
installed, taking care to maintain the proper polarity to protect the equipment and
assure user safety.
There is provision for changing the selected line voltage and for changing the fuse.
The line fuse value depends on the line voltage as indicated above the Power
Module. Figure 3 illustrates the fuse access and voltage selection mechanisms. The
Power Module is designed to accept one ¼ × 1-1/8 fuse or two 5 × 20 mm fuses.
Line Voltage Selection
➧ If the IIC-200 has been in operation, turn it off and wait at least 5 minutes for
voltages to decay to safe levels.
Disconnect the power cord.
➧ Insert a small screwdriver under the cover tab at the top of the Power Module.
➧ Gently pry open the voltage selector cover and rotate the voltage selector until the
setting for the local line voltage is facing you.
Check that the appropriate fuse(s) have been installed. (1/2 Ampere T time delay for
100/120 V AC; ¼ Ampere, T time delay for 220/240 V AC).
➧ Close the cover making sure the desired voltage setting appears in the window.
Normally, the correct voltage setting and line fuses for your area will be installed at
the factory, provided that information was specified in the order.
