When the output terminal is grounded
If the positive output terminal is connected to the chassis terminal, the positive output termi-
nal is at ground potential. The cable and load that are connected to the output terminal
(including the sensing terminal) will only require an insulation capacity that is greater than or
equal to the maximum output voltage of the PWX series with respect to the chassis. There is
no need to provide insulation that is greater than or equal to the isolation voltage of the PWX
series.
The same holds true when the negative terminal is connected to the chassis terminal. The
cable and load require an insulation capacity that is greater than or equal to the maximum
output voltage of the PWX series.
For safety reasons, connect one of the output terminals to the chassis terminal unless your
application requires the output terminals to be floating.

Because the positive output
terminal is at ground
potential, the section shown
on a gray background must
have an insulation capacity
greater than or equal to the
maximum output voltage
relative to the chassis.
