4. Installation instructions
The maximum ambient temperature must be obser-
ved.
There must be sufficient circulation of air.
Neighboring devices that produce heat must be mounted
at a suitable distance.
The preferred mounting method is on a horizontal rail.
The device must be protected from vibrations.
8. Electrical connections
●
Terminals without internal connections (1, 2, 3, 6
and 12) must remain free and must not be used for
other purposes.
●
Ex devices may only be operated with a DC power
supply of upto Um = 125 V DC.
5. Mounting the device
The SINEAX B 812 device is mounted on a top-hat rail.
Snap the device housing onto the top-hat rail (EN 50 022) (see Fig. 2).

×15 or 35×7.5 mm.
6. Removal of the device
Remove the device from the top-hat rail as shown in Fig. 3.

For the correct functioning of the communication, a
250
Ω communication resistor is required in series with the
measuring circuit. Please observe that the maximum load
on the B 812 output resulting from additional devices and
the resistance of the wires is not exceeded.

9. Commissioning
The installation and wiring must be checked before commissioning, and
in particular the permitted power supply voltage must be checked (see
the rating label).
