PA interface
Caution!
Have electrical connections installed only by qualified electricians!
The interface must only be connected to circuits which cannot become
dangerously active (SELV / PELV).
The two conductors in the two-core cable have different colors. Usually, red
(B conductor) and green (A conductor) are used. However, other colors can be
used as well.

Fieldbus terminals PROFIBUS
®
PA with connector
The fieldbus is connected to the supply terminals of the device
(terminals 51–54):
• grounding
= terminal 51 / 54
• cable red (B conductor) = terminal 52 +
• cable green (A conductor)= terminal 53 -
The connection to the PROFIBUS
®
depends on the realization on site but
should be shielded.
Note!
The supply voltage of the PROFIBUS
®
PA interface must be bus-powered. It is
not supplied by the converter.
