Optionally the following modules are allowed to be used:
In type of protection "Intrinsic Safety" (Ex ia IIC resp. Ex ib IIC)
only for the connection to a certified intrinsically safe circuit with
the following maximum values:
Plug-In module for
shutdown-function
(terminals +51 / -52 resp.
+85 / -86)

= 1.1 W
effective internal capacitance: C
i
= 3.7 nF
The effective internal inductance is negligibly small.
IMPORTANT (NOTE)
• The intrinsically safe circuits themselves are safe galvanically separated up to a voltage of
60 V. The "Local interface for communication (LKS) and programming interface (X5)" is
connected with the signal circuit.
