6. Exchanging frontplates
Apply gentle pressure to the transparent cover as shown in
Fig. 3 (left) until it pops out on the opposite side. The label in
the cover can be replaced and used for notes.
After replacing the label in the transparent cover, the trans-
parent cover can be snapped into the front of the device
again. This is done by inserting it behind the edge at the
bottom and pressing it gently down and to the rear with the
finger until it snaps into place (right side of Fig. 3).

7. Mounting
The SINEAX TI 807 can be mounted either on a top-hat rail or
directly onto a wall or mounting plate.
Make sure that the ambient temperature stays
within the permissible limits:
– 25 and + 55 °C for standard instruments
– 20 and + 55 °C for instruments in Ex version!
7.1 Top-hat rail mounting
Simply clip the device onto the top-hat rail (EN 50 022) (see
Fig. 4).
7.2 Wall mounting
While pressing the latch (4) in the base of the device (Fig. 5,
left) pull out the transmitter securing brackets (1). To return
the brackets to their original positions, the latch (5) in the
base of the device has to be depressed before applying
pressure to the securing brackets (1) (see Fig. 5, right).
