1 INTRODUCTION

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 or II 2 G Ex de [ia] IIC T6

II 2(1) G Ex de [ia] IIC T6II 2(1) G Ex de [ia] IIC T6 converter housing in type of protection increased safety "Ex e" in accordance with EN 60079-

• 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(1) G Ex d [ia] IIC T6II 2(1) G Ex d [ia] IIC T6 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).

WARNING!

"Ex d" approved cable glands / blind plugs are not

not part of the standard delivery package and

notnot

must be provided by the customer or explicitly ordered at the manufacturer.

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:

Uo = 8,2 V Io = 210 mA Po = 435 mW Co = 1,3 μF or 0,8 μF Lo = 0,5 mH or 1,2 mH
