Instruction on Using the Output Terminals
The PSF Series is a floating type power supply unit.
Connect either output terminal on the rear panel with the
GND terminal of the frame, if output should be grounded.
The output terminals on the front panel are auxiliary output
terminals, whose maximum current is 3A(400H) or
6A(800H). Note that using the front output terminals may
not satisfy the electrical specifications.
Do not use the front and rear output terminals simultaneously.
Using them together may result in troubles.

Instruction on Turning On Power
When the PSF Series power supply unit is turned on, the
version data of the internal ROM are displayed, the model
name, presence or absence of the interface, address and
other data are displayed, and then the set voltage and
current are displayed.

Precaution for turning off power
The PSF Series power supply unit stores set values
immediately before the source voltage is shut off or the
POWER switch is turned off. These stored values serve
as the initial values when it is turned on next time.
Once power is turned on or off, the user should wait for five
seconds or more before turning it off or on. If power is
turned on and off repeatedly at intervals of five seconds or
less, the unit may fail to store the set values, the power
fuse may be deteriorated due to a fault of the rush current
limit circuit, or the POWER switch may become defective.
