ATEXInstallation General installation rules


5 Installation

5.1 General installation rules

DANGERExplosion hazard from electrostatic discharge or brush dischargeLife-threatening injuries or ignition of explosive atmospheres▶ Avoid actions that could lead to electrostatic discharges. For example, do not wipe the

coated surface of the transmitter using a piece of cloth.▶ Install the device in zone 1 or 21 so as to avoid the risk of electrostatic discharges and

brush discharges caused by rapid dust flow.

Modifying the coriolis mass flow meter as well as using unauthorized parts is prohibited andwill void the certification.

▪ Only trained personnel may install and operate the device in an industrial environment.

▪ The instructions have to be read and understood by all persons authorized with thetransport, storage, installation, electrical installation, commissioning, operation, mainte-nance and disposal of the Coriolis mass flow meter in hazardous areas.

▪ The respective applicable national safety regulations concerning the installation of theCoriolis mass flow meter in hazardous areas must be followed.

▪ Only media to which the wetted parts are sufficiently resistant may be used.

▪ The use of suitable cable glands must be ensured, see Threads for cable glands[} 13].

▪ Ambient and medium temperature must not exceed the respective maximum values forthe applicable Temperature specification by temperature classes [} 46].

▪ The integral type and the remote-type transmitter must not be insulated.

Threads for cable glands

ATEXInstallation


5.2 Threads for cable glands

The terminal box in the transmitter for connecting the sensor is certified as Ex i. IP66/67-certified cable glands and blind plugs must be used for this connection. At a minimum,the allowable temperature range for cable glands and blind plugs must extend from -40...+80 °C. Blind plugs for redundant bushings and cable glands are factory-installed.

The housing of the transmitter is designed as type of protection Ex db. Optionally, the ter-minal box for the power supply and the inputs/outputs is also certified as Ex e. Properlycertified cable glands and blind plugs must be used for this purpose. At a minimum, theallowable temperature range for cable glands and blind plugs must extend from -40...+80 °C. The type of protection is to be indicated on the nameplate's identificationfields, see Nameplates [} 6].

If the device is to be operated without communication lines, the cable gland providedmust be replaced by a blind plug of the same classification.

ATEXElectrical installation General rules


6 Electrical installation

6.1 General rules

DANGERInsufficient connection to the potential equalization systemLife-threatening injuries from electric shock or ignition of explosive atmospheres▶ Connect remote-type sensor via the grounding terminal outside of the housing to the

potential equalization system, see Grounding connections and intrinsically safe circuits[} 17].

▶ Connect transmitter to the potential equalization system via the grounding terminal out-side of the housing, see Grounding connections and intrinsically safe circuits [} 17].

▶ Connect grounding cable of power supply cable to the grounding screw in the terminalbox, see Grounding connections and intrinsically safe circuits [} 17].

▪ The relevant national standards must be considered for the electrical installation.

▪ Rotamass must be integrated into the potential equalization system of the hazardousarea.

▪ The potential equalization must be ensured alongside the intrinsically safe circuit.

▪ The power supply must be established with a voltage ≤ 250 V at the terminals L/+ andN/-.

▪ The grounding screw in the terminal box must be mechanically firmly connected withthe threaded hole.

▪ If the type of protection Ex e is used, cable cross sections of 0.8 to 2.5 mm2 must beused for the cables of the power supply and the cables of the inputs/outputs. The insu-lation of the cores must be stripped off 5 to 6 mm.

▪ The cable connections for the inputs/outputs must be established according to the con-nection tables [} 18]. In the process, it must be ensured that the connection typematches the corresponding position of the MS code on the nameplate.

▪ The maximum input parameters of the intrinsically safe outputs must not be exceeded.

ATEXOperation, maintenance and repair General rules


7 Operation, maintenance and repair

7.1 General rules

DANGERLife-threatening injuries from electric shock▶ Switch off power supply.▶ Secure power supply against inadvertent switch-on.▶ Check that power supply is free of voltage.

DANGERLife-threatening injuries from ignition of explosive atmospheres▶ Wait 20 minutes before opening the housing until the capacitors have discharged and

components have cooled off.▶ Avoid electrostatically charging the device, e.g. by rubbing it with dry cloths.

Modifying the coriolis mass flow meter as well as using unauthorized parts is prohibited andwill void the certification.

▪ The locking screws of the covers may be loosened and tightened only with an Allenwrench.

▪ After closing and before commissioning, it must be checked whether the locking screwsare tightened and the covers are closed.

7.2 Replacing the sensor

If a defective Rotamass TI sensor must be replaced, contact the Yokogawa service.

The medium temperature range is indicated [} 6] by the Ex code on the sensor's addi-tional nameplate. Check whether there is a change in Ex code compared to the old sen-sor. If this is the case, the medium temperature range must be compared to the haz-ardous area requirements and assessed, see Ex code [} 42].

7.3 Replacing the transmitter

If a defective transmitter must be replaced, contact the Yokogawa service.

Observe the following items in order to obtain the replacement:

▪ Replace transmitter with option /EPT with a transmitter featuring the same option

▪ Transmitters as replacement for Rotamass 3 transmitters are identified by the value 3in the MS code (position 2)

The following figure shows the relevant positions of the MS code:

For the temperature classes, this results in the following values for the maximum processtemperature:

▪ Temperature class T6 (column T6) and value of Ex code p6 (value = 68) define theintersection: Tpro, max = 49 °C






These maximum process temperatures established must be used for further determina-tion of the ambient temperatures.
