OPERATION

57

CAUTION

When the Hi-Ω function is activated, the output
terminals of the power supply unit keep on
carrying voltage even after the output is turned
off.
The Hi-Ω LED will blink when Hi-Ω function is
still active as the internal capacitors remain
charged. Voltages as high as 80V may remain at
the terminals when the output is turned off. Such a
state is very dangerous. To avoid accidents,
isolate the output terminals from the load cables
completely with a relay or switch.
