Legal information
Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be
used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property
damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions. Qualified
personnel are those who, based on their training and experience, are capable of identifying risks and avoiding
potential hazards when working with these products/systems.

1.8 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines and
networks. Systems, machines and components should only be connected to the enterprise
network or the internet if and to the extent necessary and with appropriate security measures
(e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit:
http://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more secure.
Siemens strongly recommends to apply product updates as soon as available and to always
use the latest product versions. Use of product versions that are no longer supported, and
failure to apply latest updates may increase customer’s exposure to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under

Installation variations
Note
Requirements for safe installation
● Remote sensor FCS300 can be installed in Zone 1, Div. 1 as Intrinsically Safe or
Flameproof.
● Standard remote installation with FCT030 because the connection is certified Intrinsically
Safe. however flameproof seals and conduit (for IS cable) can be used.
● Requirement for IS circuit is that the maximum input voltage Vi to DSL is 20 VDC, Ii is
maximum 484 mA, Pi < 2.3 W
2.4.2 Maximum temperature specifications for Ex use
Maximum temperature specifications for Ex use
FC310 flowmeter
Temperature classification with and without dust is related to the process temperature and
ambient temperature as listed below.
The maximum allowable process fluid temperatures with respect to temperature class for the
device when used with potentially explosive gases in a maximum ambient temperature of
+60°C are:
Ta (°C) Maximum Process Temperature per Temperature Class (°C)
T6 T5 T4 T3
60 70 70 70 70
55 85 100 100 100
50 85 100 130 130
45 85 100 135 160
40 85 100 135 190
35 85 100 135 200
30 85 100 135 200
For installation in environment with max 5 mm dust, the maximum process temperatures shall
be as follows:
Ta (°C) Maximum Process Temperature per Temperature
Class (°C)
60 70
55 100
50 130
45 160
40 190

Operating Instructions, 06/2018, A5E44036384-AA 19

Ta (°C) Maximum Process Temperature per Temperature
Class (°C)
35 200
30 200
Additionally, the maximum surface temperature of the overall device shall be:
● If Tprocess ≤ 85°C, maximum surface temperature = 85°C.
● If Tprocess > 85°C, maximum surface temperature = process temperature.
For installation in environment with max 500 mm dust, the maximum process temperature shall
be as follows:
Ta (°C) Maximum Process Temperature per Temperature
Class (°C)
60 -40
55 -10
50 20
45 50
40 80
35 110
30 140
Additionally, the maximum surface temperature of the overall device shall be:
● If Tprocess ≤ 85°C, maximum surface temperature = 85°C.
● If Tprocess > 85°C, maximum surface temperature = Tprocess.
