6. OPERATION PROCEDURES
6.1 . STAND-ALONE OPERATION
When using the power supply in stand-alone mode, simply
operate by manipulation of the panel switches and
adjustment knobs as needed.
However, be sure that MASTER / SLAVE switch is set to
MASTER position.
6.2. SERIAL CONNECTION
Two or more units of the power supply can be hooked up in
series to achieve higher output voltage. The resulted output
will be sum of the outputs of the individual units. In this
situation, however, care must be taken that the voltage of
neither of the terminals with respect to the chassis GND
exceed the ground proof voltage of + 180V
• SINGLE VOLTAGE CONNECTION
For connection as shown in FIG.6.1, the output voltage
will be the sum of individual supplies and output
current will be limited to within the value specified for
a single unit whichever is lower. For positive ground
terminal to output positive point and for negative
ground system, hook-up the ground terminal to the
negative output point.
• PLUS / MINUS CONNECTION
For connection as shown in FIG.6.2 where the intermediate
point is hooked up to ground, the configuration can be used as
Plus / Minus power supply.
