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

DC 24 V to AC 230 V, 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.
