In exceptional instances, I/O modules can be directly connected to the
field supply!
The 24 V field supply can be connected also directly to a bus module, if the
connection points are not needed for the peripheral device supply. In this case,
the connection points need the connection to the power jumper contacts.

The field-side power supply is automatically derived from the power jumper
contacts when snapping an I/O module.
The current load of the power contacts must not exceed 10 A on a continual
basis.
By inserting an additional power supply module, the field supply via the power
contacts is disrupted. From there a new power supply occurs which may also
contain a new voltage potential.

Re-establish the ground connection when the connection to the power
jumper contacts is disrupted!
Some I/O modules have no or very few power contacts (depending on the I/O
function). Due to this, the passing through of the relevant potential is disrupted. If
you require a field supply via power jumper contacts for subsequent I/O modules,
then you have to use a power supply module.
Note the data sheets of the I/O modules.
Use a spacer module when setting up a node with different potentials!
In the case of a node setup with different potentials, e.g. the alteration from
24 VDC to 230 VAC, you should use a spacer module. The optical separation of
the potentials acts as a warning to heed caution in the case of wiring and
maintenance works. Thus, you can prevent the results of wiring errors.
