Ensure the reverse withstand voltage of the diode is
CAUTION able to withstand 2 times the rated output voltage of
the power supply and the forward current capacity can
withstand twice to 10 times the rated output current
of the power supply.
Ensure the diode is able to withstand the heat
generated in the following scenarios.
When the diode is used to limit reverse voltage,
remote sensing cannot be used.

Grounding
The output terminals of the PHU power supplies are isolated with
respect to the protective grounding terminal. The insulation capacity
of the load, the load cables, and other connected devices must be
taken into consideration when connected to the protective ground or
when floating.

Floating As the output terminals are floating, the load and
all load cables must have an insulation capacity
that is greater than the isolation voltage of the
power supply.

( ) Insulation capacity ≥ isolation voltage
of power supply

If the insulation capacity of the load and load cables
WARNING are not greater than the isolation voltage of the power
supply, electric shock may occur.
