3-1. INSTALLATION
a. The MVC-300 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-300 is detachable by
removal of the knob and locking nut from the MANUAL VOLTAGE ADJUST control and the four
corner screws. The MVC-300 can be installed in any position without affecting its operating charac-
teristics, however, it is preferable that the device be mounted vertically to improve ventilation. The
MANUAL VOLTAGE ADJUST control can be removed and installed remotely by using terminals 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-300 be connected to provide an output which corresponds to the voltage regulator ratings
in order to prevent damage to the MVC-300 or the regulator. When the MVC-300 and voltage
regulator are properly matched, the MVC-300 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-300 has a wire jumper connected from the printed
circuit board of the MVC-300 to the barrier strip. Column 4 indicates the correct terminal for this
jumper connection.
