nal range might cause a zero point offset. In this case a zero point adjustment might be
necessary.
3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.
Permissible supply voltage:
U
v
= 14…30 VDC
Permissible load:
R
a
= (U

Connecting the switching outputs (optional)
The switching outputs are potential-free.
They are electrically isolated from the sup-
ply side (see Figure 2).
Therefore you can connect the load on the
high-side (PNP-style) or the low-side (NPN-
style) as long as you use only one switching
output.

Figure 2: Switching outputs isolated from supply
Due to the limited number of pins either the low-side or the high-side is combined internally
and routed to Pin 5. Therefore you have to connect both loads as shown below if you want
to use both switching outputs.
