9 General installation rules Installation 4 Installation 4.1 General installation rules DANGER Explosion hazard from electrostatic discharge or brush discharge Life-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. Modifying the coriolis mass flow meter as well as using unauthorized parts is prohibited and will 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 the transport, storage, installation, electrical installation, commissioning, operation, maintenance and disposal of the Coriolis mass flow meter in hazardous areas. Install according National Electrical Code. Intrinsically safe circuits must be installed according NFPA 70 and ANSI / ISA RP Only media to which the wetted parts are sufficiently resistant may be used. The use of suitable cable connections must be ensured, see Threads for cable connections [} 10]. Ambient and medium temperature must not exceed the respective maximum values for the applicable specification by temperature es [} 49]. The integral type and the remote-type transmitter must not be insulated. Specified maximum ambient temperature of cables (power supply-, I/O- and remote cable) must be 20 C / 41 F above maximum ambient temperature of flowmeter. Regard the Control Drawings, see Control Drawings [} 19]. IM 01U10X03-00EN-R, 1st edition, / 66

It allows the evaluation of ambient and max process temperatures for each temperature. If no Ex-code is shown, temperatures are given in the user s manual. The Ex-Code has the following structure: a.p6.p5.p4.p3.p2 where a, p6, p5, p4, p3 and p2 are integer numbers with the following meaning: a: ambient temperature column number p6: max process temperature row number for temperature T6 p5: max process temperature row number for temperature T5 p4: max process temperature row number for temperature T4 p3: max process temperature row number for temperature T3 p2: max process temperature row number for temperature T2 and T1 evaluation by Ex-Code: The process temperature for each temperature (T6 to T1) is evaluated by choosing the row according to the corresponding row number (p6 to p2) in Table 6 (process temperature). The ambient temperature is evaluated by choosing the applicable ambient temperature table (Table 7 or Table 8) according to the model code of Rotamass. The applicable column is specified by the value of a and temperature (T6 to T1). The row identified by the next larger process temperature compared to the evaluated max process temperature gives the ambient temperature. This ambient temperature value has to be compared with the max process temperature value; the smaller one determines the ambient temperature (see example below).

The ambient temperature is evaluated by choosing the applicable ambient temperature table (Table 9 or Table 10 or Table 11) according to the model code of Rotamass. The applicable column is specified by the value of a and temperature (T6 to T1). The row identified by the next larger process temperature compared to the evaluated max process temperature gives the ambient temperature.

33 General rules Operation, maintenance and repair 6 Operation, maintenance and repair 6.1 General rules DANGER Life-threatening injuries from electric shock Switch off power supply. Secure power supply against inadvertent switch-on. Check that power supply is free of voltage. DANGER Life-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 and will void the certification. The locking screws of the covers may be loosened and tightened only with an Allen wrench. After closing and before commissioning, it must be checked whether the locking screws are tightened and the covers are closed. 6.2 Replacing the sensor If a defective Rotamass TI sensor must be replaced, contact the Yokogawa service. The medium temperature range is indicated [} 4] by the Ex code on the sensor's additional nameplate. Check whether there is a change in Ex code compared to the old sensor. If this is the case, the medium temperature range must be compared to the hazardous area requirements and assessed, see Ex code [} 44]. 6.3 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 3 in the MS code (position 2) IM 01U10X03-00EN-R, 1st edition, / 66
