Connect the device only to intrinsically-safe certified circuits. Observe the following maximum
values for the display when connecting:
•
U
i
= 30 V
•
I
i
= 120 mA
•
P
i
= 1 W
•
L
i
= 0 mH
•
C
i
= 45 nF
CAUTION!
The capacity and inductance of the connecting cable between the supply device, display and
operating unit and connected sensor as well as the capacity and inductance of the sensor must
also be taken into account.
WARNING!
Also, when operating the indicators outside of the hazardous area, the connection must be made
to an intrinsically safe circuit. When connecting to non-intrinsically safe circuits, there is a risk
of damage to the safety-defining components.
