( ) Insulation capacity ≥ isolation voltage
of power supply
If the insulation capacity of the load and load cables
are not greater than the isolation voltage of the power
supply, electric shock may occur.
If the positive or negative terminal is connected to
the protective ground terminal, the insulation
capacity needed for the load and load cables is
greatly reduced. The insulation capacity only
needs to be greater than the maximum output
voltage of the power supply with respect to
ground.

If using external voltage control, do not ground the
external voltage terminal as this will create a short
circuit.
