Caution
High-potential test equipment should be applied with extreme care.
Incorrect application of dielectric test voltages will damage the
MVC 236.
Connection drawings for typical MVC 236 applications are provided in Figure 5 and Figure 6.
Table 1 serves as a legend for the Auto/Off/Manual Switch of Figure 5.
For Figure 6, switch contacts 1 and 2 are closed for manual operation and switch contacts 3 and 4 are
closed for auto operation.

Connection Guidelines
Observe the following guidelines when making MVC 236 connections.
Input Power
Operating power is applied at MVC 236 terminals 23 and 24. The MVC 236 and operating power wiring
should be protected with fuses. Configure the MVC 236 for the applied, nominal operating power by
connecting the jumper from terminal TB2-TAP to the proper terminal on TB2 (60, 120, or 240).
Output (Field) Voltage
Select the desired output (field) voltage (32 Vdc, 63 Vdc, or 125 Vdc) by connecting the jumper wire from
terminal TB1-COM (Field Voltage) to the proper terminal.
Frequency Selection
Configure the MVC 236 for the operating power frequency. Connect a jumper wire between terminal TB1-
COM (Frequency Hz) and the appropriate terminal for 50 Hz to 100 Hz operation or 100 Hz to 200 Hz
operation. For an operating power frequency within the range of 200 Hz to 400 Hz, omit the jumper.
Manual Voltage Adjust Potentiometer
Connect the manual voltage adjust potentiometer to MVC 236 terminals TB1-14, TB1-15, and TB1-16 as
shown in the connection diagrams. If desired, a Basler Electric Motor Operated Control with a 10 k
Ω
control element can be used instead of the supplied potentiometer.
