The internal power supply voltage for the module's circuitry is carried out via the I/O bus (pro-
vided by a bus module or a CPU). Thus, the current consumption from 24 VDC power supply at
the terminals L+/UP and M/ZP of the CPU/bus module increases by 10 mA per DO572.
An external power supply connection is not needed.
WARNING!
Risk of death by electric shock!
The terminals of the module can carry 240 V voltage.
Make sure that all voltage sources (supply and process voltage) are switched
off before you begin with operations at the system.
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.
