The voltage is automatically supplied when the I/O modules are snapped to-
gether. Self-cleaning power jumper contacts (P.J.C.s) ensure safe connections.
The current capacity of the power contacts is 10 A max.

The PE contact is a preceding ground (earth) contact corresponding to the
standards which can be used as a protective earth. The contact has a leakage
capacity of 125 A.

Warning
Produce a low impedance connection from the carrier rail to the PE contact
point in the switch cabinet.

Attention
Depending on the I/O function, some modules do not have P.J.C.s. It is im-
portant to note this when assembling a node. Many modules require field side
power, many do not. Please review the circuit diagrams of the individual mod-
ules. An additional power supply module may be necessary.
Refer to the individual terminal/module data sheets!

When adding a power supply module, the field supply is always interrupted at
the power contacts. From this point a new power supply is made, which can
also include a potential change. This feature guarantees a high degree of sys-
tem flexibility.
