PMX_MULTI
Installation | Output Terminal Insulation
When the output terminal is grounded
If the positive output terminal is connected to the chassis terminal, the positive output terminal 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 PMX
seres (multiple-output) with respect to the chassis.
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 PMX
seres (multiple-output).
For safety reasons, connect one of the output terminals to the chassis terminal unless your application
requires the output terminals to be floating.
