Terminals 1.9, 2.9 and 3.9: Process supply voltage ZP = 0 V
With a separate UP3 power supply, the digital outputs can be switched off
externally. This way, an emergency-off functionality can be realized.

WARNING!
Removal/Insertion under power
The devices are not designed for removal or insertion under power. Because of
unforeseeable consequences, it is not allowed to plug or unplug devices with
the power being ON.
Make sure that all voltage sources (supply and process voltage) are switched
off before you
–
connect or disconnect any signal or terminal block
–
remove, mount or replace a module.
Disconnecting any powered devices while energized in a hazardous location
could result in an electric arc, which could create a flammable ignition resulting
in fire or explosion.
Make sure that power is removed and that the area has been thoroughly
checked to ensure that flammable materials are not present prior to proceeding.
The devices must not be opened when in operation. The same applies to the
network interfaces.
CAUTION!
There is no galvanic isolation between the analog circuitry and ZP/UP. There-
fore, the analog sensors must be galvanically isolated in order to avoid loops via
the ground potential or the supply voltage.
CAUTION!
Because of their common reference potential, analog current inputs cannot
be circuited in series, neither within the module nor with channels of other
modules.
