Grounding
The output terminals of the PSW 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.

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