3 PRELIMINARY INSTRUCTIONS
Be sure to read through this section before using the PSF Series power supply unit.
●
Checking the Source Voltage
Use the PSF Series power supply unit within the rated
source voltage range, which is AC100V to 240V
(allowance: ±10%),single-phase, 50Hz or 60Hz.
●
Connecting the AC Power Cable
Be sure to use the AC power cable supplied with the product.
●
AC Power Cable
Attached AC cable is different according to the destination.
Make sure the rating of the AC cable.
●
Grounding
Be sure to ground the PSF Series power supply unit to
prevent electric shock or electrocution.
A failure of grounding the unit may result in malfunctioning
due to external noises and/or increased noises generated
by the unit.
Be sure to connect the GND terminal if a 2P-3P conversion
plug is used owing to unavoidable circumstances.
●
Instructions on Using the PSF Series in the Floating
Condition
Using the PSF Series power supply unit in the floating
condition is subject to high potential between the frame
and output terminals.
If the frame and output terminals are short-circuited in this
condition, a measuring instrument or load connected with
the PSF Series may be broken. Be very careful. Such
high potential may remain in the noise reduction capacitor
after use. Never short-circuit the terminal or touch them
by hand. Disobedience to this instruction may cause
electric shock or electrocution.
