Electronic Housing Rotating
The electronic housing can be rotated in order to have a better position of the digital display. To
rotate it, use the Housing Rotation Set Screw. (See Figure 1.4).
The local indicator itself can also be rotated. (See Figure 2.4).
Electric Wiring
Reach the wiring block by removing the Electrical Connection Cover. This cover can be locked by
the cover locking screw. To release the cover, rotate the locking screw clockwise.
The wiring block has screws on which fork or ring-type terminals can be fastened.

For convenience there are two ground terminals: one inside the cover and one external, located
close to the conduit entries. (See Figure 1.5).

The FY303 uses the 31.25 kbit/s voltage mode option for the physical signaling. All other devices on
the same bus must use the same signaling. All devices are connected in parallel along the same
pair of wires.
Various types of Profibus devices may be connected on the same bus.
