INSTALLATION AND OPERATION
3-1. INSTALLATION
a. The MVC-301 is designed for 'through-the-panel' mounting. Refer to the drilling template of
Figure 3-1 and to the outline drawing Figure 3-2. The front panel of the MVC-301 is detachable by
removal of the four corner screws. The MVC-301 can be installed in any position without affecting
its operating characteristics, however, it is preferable that the device be mounted vertically to
improve ventilation. The MANUAL VOLTAGE ADJUST control can be connected by using termi-
nals 14, 15 and 16 or a Basler motor operated control (MOC 2) with a 10 k ohm control element can
be connected to terminal 14, 15, and 16. See Figure 3-3 Interconnection Diagram. It is imperative
that the MVC-301 be connected to provide an output which corresponds to the voltage regulator
ratings in order to prevent damage to the MVC-301 or the regulator. When the MVC-301 and
voltage regulator are properly matched, the MVC-301 provides smooth control of the generator
output voltage in the manual mode.
b. The chart (Table 3-1) is used to determine the appropriate input voltage and to select the output
voltage. Based on voltage regulator model, from column 1, the proper voltage input rating from
column 3 is selected and connections are made between the generator and terminals 23 and 24
which will supply the specified voltage. The MVC-301 has a wire jumper connected from the printed
circuit board of the MVC-301 to the barrier strip. Column 4 indicates the correct terminal for this
jumper connection.
