Proline Promag 53 2 Endress+Hauser General warnings • For installation, use and maintenance of the flow meter, the instruction manual and the following standards shall be observed: – GB50257-1996 "Code for construction and acceptance of electric device for explosive atmospheres and fire hazard electrical equipment installation engineering" – GB3836.13-1997 "Electrical apparatus for explosive gas atmospheres – Part 13: Repair and overhaul for apparatus used in explosive gas atmospheres" – GB3836.15-2000 "Electrical apparatus for explosive gas atmospheres – Part 15: Electrical installations in hazardous area (other than mines)" – GB3836.16-2006 "Electrical apparatus for explosive gas atmospheres – Part 16: Inspection and maintenance of electrical installation (other than mines)" – GB15577-2007: Safety regulations for dust explosion prevention and protection". (Only if installed in dust hazardous areas.) – GB12476.2-2006 "Electrical apparatus for use in the presence combustible dust – Part 1-2: Electrical apparatus protected by enclosures and surface temperature limitation – selection, installation and maintenance" (only if installed in dust hazardous areas). • The flow meter shall not be modified in order to ensure the explosion protection performance of the equipment. Any change may impair safety. • Installation, connection to the electricity supply, commissioning and maintenance of the devices must be carried out by qualified specialists trained to work on Ex-rated devices. • Compliance with all of the technical data of the device (see nameplate) is mandatory. • Open the device only when it is de-energized (and after a delay of at least 10 minutes following shutdown of the power supply) or in non-hazardous (classified) locations. • It is not permissible to connect the service adapter whilst the atmosphere is considered to be explosive. • Opening the transmitter housing and the connection housing of the remote version is only permitted for a brief time. During this time, ensure that no dust or water enters the housing. • To guarantee resistance to dust and water, the transmitter housing, the connection housing of the remote version and the cable entries must be tightly sealed. • The suitability of the device in the event of simultaneous occurrence of gas-air and dust-air mixtures requires an additional assessment. Special conditions • The device must be integrated into the potential equalization system. Potential must be equalized along the intrinsically safe sensor circuits. Further information is provided in the "Potential equalization" section on Page 9. • The sensors may only be used for those media, for which the wetted parts are known to be suitable. • For the application of the transmitters in an ambient temperature of less than –20 °C suitable cables and cable entries certified for this condition shall be used. Entry holes which are not needed, shall be closed by stopping plugs separately certified for this purpose. Installation instructions • For terminals No. 20 to No. 27 of the transmitter, only devices with ratings Um  260 V and Im  500 mA are allowed to be connected (does not apply to intrinsically safe circuits). • The measuring device must only be used in the permitted temperature class. The values of the individual temperature classes can be found in the temperature tables on Page 6. For Zone 21: The surface temperature of the measuring device must not exceed 2/3 of the ignition temperature of a dust cloud. The maximum surface temperature must maintain a safe distance of 75 °C to the smolder temperature of a dust layer of 5 mm. Example: Operation in temperature class T4 (135 °C) is, therefore, suitable for dust with an ignition temperature of 202.5 °C (1.5 × 135 °C or 135 °C = 2/3 of 202.5 °C) and a smolder temperature of 210 °C (135 °C + 75 °C). • The following applies when using the terminal compartment in type of protection "flameproof/Ex d":  Only cable entries and cable glands, which are approved by NEPSI in accordance with GB3836.1-2010 and GB3836.2-2010 and which are suitable for an operating temperature of up to 80 °C, they shall be used. • The following applies when using the terminal compartment in type of protection "increased safety/Ex e":  Only cable entries, cable glands and blanking plugs, which are approved by NEPSI in accordance with GB3836.1-2010 and GB3836.3-2010 and which are suitable for an operating temperature of up to 80 °C and for an ingress protection of IP67, they shall be used. Alternatively Ex e cable glands specified or provided by Endress+Hauser Flowtec AG can be used. The cables must be installed in such a way, that they are fixed in place in order to ensure adequate strain relief. • Suitable cables and suitable, certified cable glands, cable entries and blanking plugs must be used for measuring devices operated at temperatures below –20 °C. • The cable entries and openings not used must be sealed tight with suitable components.

NEPSI Zone 1, Zone 21 0 Endress+Hauser 3 Installation instructions (continued) • Turning the local display: the screw cap has to be removed before the local display can be turned, and this must be done with the device de-energized (and after a delay of at least 10 minutes following shutdown of the power supply) or when the area is known to be non-hazardous. " Caution! The explosion group for the measuring device can be IIC. However, it is reduced to IIB if the permitted, external capacitance/inductance for the intrinsically safe communication circuits is increased (see Page 13). # Warning! For entity concept, the criteria for interconnection between the I/O circuits and the associated circuits is as follow: • Uo  Ui • Io  Ii • Po  Pi • Co  Ci + Cc • Lo  Li + Lc Cc and Lc stand for the distributed capacitance and distributed inductance of the cable. Turning the transmitter housing 1. Unscrew the grub screw. 2. Rotate the transmitter housing cautiously clockwise until the end stop (end of the thread). 3. Rotate the transmitter housing counter-clockwise (max. 360°) in the wanted position. 4. Tighten the grub screw properly after each manipulation # Warning! Ensure that the grub screw is tightened properly.

In the associated temperature table (compact version), the selection of the measuring device (Promag 53P), the nominal diameter (DN 25), the lining material (PTFE) and the ambient temperature Ta (45 °C) determine the line in which the max. medium temperature can be found. 2. The fluid temperature TM (110 °C), which is smaller or equal to the max. fluid temperature, determines the column, i.e. the temperature class, for gas (110 °C  130 °C T4). 3. The maximum temperature of the calculated temperature class corresponds to the maximum surface temperature (T4 = 135 °C = maximum surface temperature for dust).

The leak-tight of the cable glands and cable entries is to ensure. Cable specification You can find information about the cable specification in the associated Operating Instructions. Potential equalization • The transmitter (compact and remote version) is to be securely connected to the potential equalization system using the screw terminal on the outside of the transmitter housing. Alternatively, the transmitter of the compact version as of serial number 4Axxxxxx000 can be connected to the potential equalization system via the pipeline if a ground connection via the pipeline according to regulations can be assured. • When using the remote version, the connection housing of the sensor must be grounded via the external screw terminal. Alternatively, the sensor can be integrated into the potential equalization via the pipeline as long as the pipeline provides a ground connection conforming to regulations. !Note! Further information about potential equalization, shielding and grounding can be found in the associated Operating Instructions.
