When the output terminal is not grounded
The cable and load that are connected to the output terminal (includ-
ing the sensor terminal) must have an insulation capacity that is
greater than the isolation voltage
*1
of the power supply with respect
to the chassis.
In addition, cables and devices that are connected to the following
pins must also have an insulation capacity that is greater than the iso-
lation voltage of the power supply.
• Pins 1 to 19 on the control terminal board on the rear panel.
This is because the above pins are at approximately the same electri-
cal potential as the positive output terminal of the power supply.

*1. Maximum allowed voltage that appears across the output ter-
minal of the power supply unit and the protective conductor
terminal (chassis terminal).
For details on the isolation voltage of each model, see Chap-
ter 7 "Speci
fi cations".

Since the output terminal is floating, the
section indicated in gray must have an
insulation capacity that is greater than
the isolation voltage of the power supply
with respect to the chassis.
