14.4 Electrical data
Connections:
Communication
Due to the arrangement, the
modules automatically contact the
backplane bus of the I/O system
SIMATIC ET 200SP / SP HA.
Load voltage
Due to the arrangement, the modules
automatically contact the power bus of
the I/O system SIMATIC ET 200SP.
exception: The power bus is not con-
tinued at the right-hand interface.
If further function modules of the
SIMATIC ET 200SP I/O system are
added to the right of the valve block,
(not permissible in combination with
SIMATIC ET 200SP HA), the load voltage
must be re-supplied for the modules.

Fuses (load side)
All valve outputs are protected against
short circuits by resettable fuses.
After an occurred short circuit has been
rectified, it might take a few seconds for
the fuse to reset.
Additionally, each electronic base module
and the left-hand connection unit are
equipped with a fuse (blow fuse).
