14-2-1-3. Adjusting Method of DC Power Source Voltage Level
(Option for M and L board specifications )
• The DC power output voltage is to be adjusted on the MONI of the power supply unit.
(See Figure 14-2-1-4-1.)
• Adjust the output voltage variable change volume knob of each DC power supply so that
the output voltage values of the Nos. 1 and 2 DC power supply are the specification values.

Note
Note 1. Carefully adjust the variable resistor so that the voltage value does not become beyond
the specified adjustment level.
Note 2. Never connect MONI 1 to 4 pins to the GND line of a power supply unit other than that to
be adjusted.
(Do not connect such GND line.)
Note 3. Before adjusting the voltage of the PS1 or PS2, disconnect the connectors of the electric
bank. (Adjust the voltage in the no-load status.)
