5.3.2 When the Output Terminal Is Grounded
If the positive output terminal is connected to the chassis terminal, the terminal is at
ground potential as shown in Fig.5-4. 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 the maximum output voltage of the PAT with respect to
the chassis. There is no need to provide insulation greater than the isolation voltage
of the PAT.
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 the maximum
output voltage of the PAT.
Fig.5-4 When the o u tp u t terminal is gro u nded
If the external voltage (Vext) output is grounded for the case shown in Fig.5-4, the
output is short-circuited (which can cause accidents).
For safety reasons, connect either output terminal to the chassis terminal unless your
application requires the output terminal to be floating.
