2 Safety instructions

2.1 Requirements for the personnel

The personnel must fulfill the following requirements for its tasks:

‣Trained, qualified specialists must have a relevant qualification for this specific function

and task.

‣Are authorized by the plant owner/operator.

‣Are familiar with federal/national regulations.

‣Before starting work, read and understand the instructions in the manual and

supplementary documentation as well as the certificates (depending on the application).

‣Follow instructions and comply with basic conditions.

2.2 Designated use

Application and media

The measuring device described in this manual is intended only for the flow measurement of

gases.

Depending on the version ordered, the measuring device can also measure potentially

explosive, flammable, poisonous and oxidizing media.

Measuring devices for use in hazardous areas or where there is an increased risk due to

process pressure, are labeled accordingly on the nameplate.

To ensure that the measuring device remains in proper condition for the operation time:

‣Keep within the specified pressure and temperature range.

‣Only use the measuring device in full compliance with the data on the nameplate and the

general conditions listed in the Operating Instructions and supplementary documentation.

‣Based on the nameplate, check whether the ordered device is permitted for the intended

use in the hazardous area (e.g. explosion protection, pressure vessel safety).

‣Use the measuring device only for media to which the process-wetted materials are

sufficiently resistant.

‣If the ambient temperature of the measuring device is outside the atmospheric

temperature, it is absolutely essential to comply with the relevant basic conditions as

specified in the device documentation.

‣Protect the measuring device permanently against corrosion from environmental

influences.

Incorrect use

Non-designated use can compromise safety. The manufacturer is not liable for damage caused

by improper or non-designated use.

LWARNING

Danger of breakage due to corrosive or abrasive fluids and ambient conditions!

‣Verify the compatibility of the process fluid with the sensor material.

‣Ensure the resistance of all fluid-wetted materials in the process.

‣Keep within the specified pressure and temperature range.

Safety instructions Proline 300 Modbus RS485

8 Endress+Hauser

NOTICE

Verification for borderline cases:

‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in

verifying the corrosion resistance of fluid-wetted materials, but does not accept any

warranty or liability as minute changes in the temperature, concentration or level of

contamination in the process can alter the corrosion resistance properties.

LWARNING

Injury from sensor being ejected!

‣The sensor gland should be opened only when in an unpressurized state.

LWARNING

Risk of injury if the process connection and gland of the sensing element are opened

under pressure.

‣The process connection and sensor gland should be opened only when in an unpressurized

state.

NOTICE

Penetration of dust and moisture when the transmitter housing is opened.

‣Only open the transmitter housing briefly, ensuring that no dust or moisture enters the

housing.

Residual risks

LWARNING

If the temperature of the media or electronics unit is high or low, this may cause the

surfaces of the device to become hot or cold. This poses a risk of burns or frostbite!

‣In the case of hot or cold medium temperatures, install appropriate protection against

contact.

2.3 Occupational safety

When working on and with the device:

‣Wear the required personal protective equipment as per national regulations.

For welding work on the piping:

‣Do not ground the welding unit via the measuring device.

If working on and with the device with wet hands:

‣Due to the increased risk of electric shock, wear suitable gloves.

2.4 Operational safety

Risk of injury.

‣Operate the device in proper technical condition and fail-safe condition only.

‣The operator is responsible for interference-free operation of the device.

2.6 IT security

Our warranty is valid only if the device is installed and used as described in the Operating

Instructions. The device is equipped with security mechanisms to protect it against any

inadvertent changes to the settings.

IT security measures, which provide additional protection for the device and associated data

transfer, must be implemented by the operators themselves in line with their security

standards.

2.7 Device-specific IT security

The device offers a range of specific functions to support protective measures on the operator's

side. These functions can be configured by the user and guarantee greater in-operation safety

if used correctly.

For detailed information on device-specific IT security, see the Operating Instructions for

the device.

2.7.1 Access via service interface (CDI-RJ45)

The device can be connected to a network via the service interface (CDI-RJ45). Device-specific

functions guarantee the secure operation of the device in a network.

The use of relevant industrial standards and guidelines that have been defined by national

and international safety committees, such as IEC/ISA62443 or the IEEE, is recommended.

This includes organizational security measures such as the assignment of access authorization

as well as technical measures such as network segmentation.

Transmitters with an Ex de approval may not be connected via the service interface (CDI-

RJ45)!

Order code for "Approval", options (Ex de): BB, C2, GB, MB, NB
