1.5 UFC 300 F(/i)-Ex
The UFC 300 F(/i)-Ex is the separate version of the ultrasonic signal converter and has
intrinsically safe connections to the ultrasonic flow sensor in separate version. The ultrasonic
signal converter is either provided with increased safety or intrinsically safe in-/outputs that are
located in the terminal compartment, which can either be configured as “Ex d” or “Ex e”.
The converter is marked with one of the following codes:
• II 2(1) G Ex de [ia] IIC T6 II 2(1) G Ex de [ia] IIC T6 II 2(1) G Ex de [ia] IIC T6 II 2(1) G Ex de [ia] IIC T6 or II 2 G Ex de [ia] IIC T6 II 2 G Ex de [ia] IIC T6 II 2 G Ex de [ia] IIC T6 II 2 G Ex de [ia] IIC T6 for the terminal compartment of the signal
converter housing in type of protection increased safety "Ex e" in accordance with EN 60079-
7.
• II 2(1) G Ex d [ia] IIC T6 II 2(1) G Ex d [ia] IIC T6 II 2(1) G Ex d [ia] IIC T6 II 2(1) G Ex d [ia] IIC T6 or II 2 G Ex d [ia] IIC T6 II 2 G Ex d [ia] IIC T6 II 2 G Ex d [ia] IIC T6 II 2 G Ex d [ia] IIC T6 for the terminal compartment of the signal
converter housing designed as flameproof enclosure "Ex d" according to EN 60079-1. The
customer must provide "Ex d" approved cable glands in accordance with the European
Directive 94/9 EC (ATEX 100a).
The terminal compartment contains the connecting terminals for the mains supply and in-
/outputs. It has three M20 x 1,5 - 6H cable/conduit entry holes for use with appropiate cable
glands, blind plugs or conduit adapters ("Ex e" or "Ex d" approved).
When conduits are used, the terminal compartment must be a flameproof enclosure "Ex d"
according to EN 60079-1. The conduits must be sealed by "Ex d" approved sealing devices, e.g. a
stopping box with setting compound, directly at the conduit entrances.
The intrinsically safe transducer output connections have the following values:
WARNING!
"Ex d" approved cable glands / blind plugs are not
not not not part of the standard delivery package and
