VIII
• Internal elements may be destroyed if a voltage outside the rated voltage is
applied.
• Maintain voltage fluctuations in the power supply within the specified range.
• Use a switch, relay, or other contact so that the rated power supply voltage will be
reached within 0.1 s. If the power supply voltage is not reached quickly enough,
the H8PS may malfunction or outputs may be unstable.
• Do not turn OFF the power supply when changing or deleting settings. The
contents of the EEPROM may be corrupted.
