The external clamp is suitable for wires up to 4 mm2 cross section. Disconnection from the equipotential bonding system is only allowed when the flowmeter is not in contact with power supplies or ground voltages outside the hazardous area. 3.2 Terminal arrangment To connect external devices to the signal output terminals, the wiring requirements for the type of protection of the compartment must also be conform to the international or national standard involved (e.g. EN 60079-14).

Binary outputs Terminals B1 and Bgnd can be configured as pulse or status output through software. Terminals B2 and Bgnd can be configured as pulse or status output to NAMUR. Galvanical separation of circuits The internal electrode circuit with type of protection "EEx ib" is galvanically connected to the aluminum signal converter housing (i.e. PE potential). The current output, the additional power supply and the internal field current circuit are galvanically connected to each other. 10 www.krohne.com 09/2010-7312232100-AD EX OPTIFLUX 4040 C R01 en OPTIFLUX 4040 C M ELECTRICAL CONNECTIONS p 3.3 Description of the output circuits The terminal compartment of the OPTIFLUX 4040 C-EEx is, with respect to the explosion protection, available in two versions. The version can be identified by the information that is listed on the data plate, which is mounted on the signal converter housing. Version A:terminal compartment "EEx de [ib]"with Um= 60 V The customer can decide in which type of explosion protection the output circuits - current output, additional power supply and binary outputs (i.e. pulse and/or status outputs) - can be driven: in type of protection "EEx ib", "EEx e" or"EEx d". If type of protection EEx e or EEx d is used, the markings for "Intrinsically safe" - that are blue o-ring around the cable gland and the blue sticker in the connection compartment - should be removed. The safety-technical maximum voltage Um (maximum effective AC or DC voltage) of the mains power supply system for the terminal compartment in type of protection EEx de [ib] is restricted to 60 V.With this maximum voltage it is guaranteed that the protective components on which the intrinsic safety of these circuits depends are not overloaded. This condition is met if the mains power supply system satisfies the PELV requirements in accordance with IEC 364/ IEC 536. WARNING!all It is nottallowed to mix two different types of protection kg. current output in type of protection ' EEx ib"and pulse/status outputs in "EEx e"or "EEx d 7 a /NFORMA T/ON! /t is allowed to change the type of protection of the terminal compartment afterwards, if it is garuanteed that the maximum voltage Um of the mains po wer supply system is always limited at 60 V! Version B: terminal compartment "EEx de"with Um= 250 V This version is intended for applications where the mains power supply system provides a maximum safety-technical voltage of Um = 250 V. The terminals can either be provided with type of protection increased safety"EEx e" according to EN 50019 or flameproof enclosure "EEx d" conform to EN 50018. Type of protection intrinsical safety"EEx ib" is not allowed for this version. Important notes (applicable for versions A and B) • The intrinsically safe "EEx ib" internal electrode circuit is supplied by the IFC 040-EEx signal converter electronics unit inside the electronics compartment. This circuit is separated from all other circuits up to a maximum voltage of Um = 250 V according to EN 50020. The internal electrode circuit with type of protection intrinsic safety"ib" is galvanically connected with the PE (housing potential). • The current output (terminals I, Igr,d) and the additional power supply (terminals 1 L=, OL=) must be galvanically separated from each other. To avoid voltage or current summation, at least one of the two circuits must be isolated from earth potential. It is not allowed to drive both circuits at the same time with grounded zener barriers. Both current circuits, including all connection cables, must be galvanically separated at all times according to the valid regulations. • Also in case of non-intrinsically safe connections, it is absolutely necessary to maintain a galvanic separation between the current output circuits and the additional power supply connections. 09/2010-7312232100-AD EX OPTIFLUX 4040 C R01 en www.krohne.com 11 El ELECTRICAL CONNECTIONS • A safe connection of the IFC 040-EEx signal converter electronics with the equipotential bonding system is achieved through the zinc-plated mounting frame,which must be securely screwed to the aluminum signal converter housing WE potential) by means of two long- shafted screws.To access the two long-shafted screws it is necessary to unscrew the display unit and fold it aside. The screws must be tightly secured with a torque of 1.3 Nm (a 2 Pt. Phillips screwdriver is recommended). 3.4 Safety-technical data A CA UT/ON!

The upper limit is determined by the maximum working voltage of the zener barrier, which in general lies a few volts below the maximum open voltage value Uo of the used zener barrier. The lower limit is determined by the sum of the minimum working voltage of the additional power supply of the OPTIFLUX 4040 C-EEx flowmeter of 14 V and the voltage drop over the zenerbarrier caused by the end-to-end resistance of the barrier and (if not neglectable) the serie cable resistance. This voltage drop can be significant. The above described determination of the external power supply voltage is explained by the following example. 14 www.krohne.com 09/2010-7312232100-AD EX OPTIFLUX 4040 C R01 en ELECTRICAL CONNECTIONS p Example with typical parameters: Zener barrier data: Uo =28 V to =93 mA Maximum working voltage =25.5 V End-to-end resistance 340 Q The voltage drop across the end-to-end resistance of the zener barrier is 22 mA x 340 52 = 7.5 V This means that the external power supply must supply an output voltage to the zener barrier that lies in the range somewhere between 21.5...25.5 V. The voltage over the terminals of the additional power supply of the OPTIFLUX 4040 C-EEx is in that case between the required 14.0...18.0 V 09/2010-7312232100-AD EX OPTIFLUX 4040 C R01 en www.krohne.com 15 OPERATION - The OPTIFLUX 4040 C can be programmed in the hazardous area with a bar magnet,without opening the flameproof housing of the converter.
