2 Basic safety instructions
2.1 Requirements for 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 these Instructions is intended only for flow measurement
of liquids and 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, in hygienic applications 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:
‣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 measuring device is not operated at atmospheric temperature, compliance with the
relevant basic conditions specified in the associated device documentation is absolutely
essential.
‣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!
‣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.

LPGmass Basic safety instructions
Endress+Hauser 7
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.
Residual risks
LWARNING
The electronics and the medium may cause the surfaces to heat up. This presents a burn
hazard!
‣For elevated fluid temperatures, ensure protection against contact to prevent burns.
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/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, gloves must be worn.
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.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet state-
of-the-art safety requirements, has been tested, and left the factory in a condition in which it
is safe to operate.
It meets general safety standards and legal requirements. It also complies with the EU
directives listed in the device-specific EU Declaration of Conformity. Endress+Hauser confirms
this by affixing the CE mark to the device.
2.6 IT security
We only provide a warranty 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 device settings.
IT security measures in line with operators' security standards and designed to provide
additional protection for the device and device data transfer must be implemented by the
operators themselves.

7.1.3 Shielding and grounding
Modbus
The shielding and grounding concept requires compliance with the following:
• Electromagnetic compatibility (EMC)
• Explosion protection
• Personal protection equipment
• National installation regulations and guidelines
• Observe cable specification →  16.
• Keep the stripped and twisted lengths of cable shield to the ground terminal as short as
possible.
• Seamless cable shielding.
Grounding of the cable shield
To comply with EMC requirements:
• Ensure the cable shield is grounded to the potential matching line at multiple points.
• Connect every local ground terminal to the potential matching line.
NOTICE
In systems without potential matching, the multiple grounding of the cable shield causes
mains frequency equalizing currents!
Damage to the bus cable shield.
‣Only ground the bus cable shield to either the local ground or the protective ground at one
end.
7.1.4 Preparing the measuring device
1. Remove dummy plug if present.
