5.1 TERMINAL CONNECTORS INTRINSICALLY SAFE APPLICATIONS
The unit is classified as group IIB/IIIC by default.
Classification of the unit as group IIC is only possible under the following conditions:
The indicator is either supplied by

the internal supply (option -PC);

the external supply connected to terminals 0 and 1 (option -PD);

The maximum values for any of those circuits are those as defined for group IIB/IIIC;

No other active external Intrinsically safe circuits may be connected to the indicator, with
exception of circuits connected to terminals 3 and 4 and/or terminals 5 and 6; the maximum
values for any of those circuits are those as defined for group IIB/IIIC.
Terminal connectors F130-P-XI:
For intrinsically safe applications, consult the safety values in the certificate.
