Ex-marking in case of connected FHX50 remote display
If the device is prepared for the remote display FHX50 (product structure: feature 030:
Display, Operation", option L or M), the Ex marking of some certificates changes according
to the following table 1):
Feature 010 ("Approval") Feature 030 ("Display, Operation") Ex-marking
BE L or M ATEX II 1D Ex ta [ia] IIIC T500 xx°C Da
BF L or M ATEX II 1/2 D Ex ta [ia Db] IIIC Txx°C Da/Db
BG L or M ATEX II 3G Ex nA [ia Ga] IIC T6 Gc
BH L or M ATEX II 3G Ex ic [ia Ga] IIC T6 Gc
B3 L or M ATEX II 1/2G Ex d [ia] IIC T6 Ga/Gb,
ATEX II 1/2D Ex ta [ia Db] IIIC Txx°C Da/Db

Endress+Hauser 13
2 Basic safety instructions
2.1 Requirements for the personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣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.
The operating personnel must fulfill the following requirements:
‣Are instructed and authorized according to the requirements of the task by the facility's
owner-operator.
‣Follow the instructions in this manual.
2.2 Designated use
Application and measured materials
The measuring device described in these Operating Instructions is intended only for level
and interface measurement of liquids. Depending on the version ordered the device can
also measure potentially explosive, flammable, poisonous and oxidizing materials.
Observing the limit values specified in the "Technical data" and listed in the Operating
Instructions and supplementary documentation, the measuring device may be used for the
following measurements only:
‣Measured process variable: Level and/or interface
‣Calculated process variable: Volume oder mass in arbitrarily shaped vessels (calculated
from the level by the linearization functionality)
To ensure that the measuring device remains in proper condition for the operation time:
‣Use the measuring device only for measured materials against which the process-
wetted materials are adequately resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣For special measured materials and cleaning agents, Endress+Hauser is glad to provide
assistance in verifying the corrosion resistance of wetted materials, but does not accept
any warranty or liability.
Residual risk
The electronics housing and its built-in components such as display module, main
electronics module and I/O electronics module may heat to 80 °C (176 °F) during operation
through heat transfer from the process as well as power dissipation within the electronics.
During operation the sensor may assume a temperature near the temperature of the
measured material.
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order 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.
With divisible probe rods, medium may penetrate into the joints between the indivual
parts of the rod. This medium may escape when loosening the joints. In the case of
dangerous (e.g. aggressive or toxic) media this may cause injuries.
‣When loosening the joints between the individual parts of the probe rod: Wear
appropriate protective equipment according to the medium.
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.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers.
‣If, despite this, modifications are required, consult with the manufacturer.
Repair
To ensure continued operational safety and reliability,
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to repair of an electrical device.
‣Use original spare parts and accessories from the manufacturer only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the
hazardous area (e.g. explosion protection, pressure vessel safety):
‣Based on the nameplate, check whether the ordered device is permitted for the
intended use in the hazardous area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of these Instructions.
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.
NOTICE
Loss of degree of protection by opening of the device in humid environments
‣If the device is opened in a humid environment, the degree of protection indicated on
the nameplate is no longer valid. This may also impair the safe operation of the device.
2.5.1 CE mark
The measuring system meets the legal requirements of the applicable EC guidelines. These
are listed in the corresponding EC Declaration of Conformity together with the standards
applied.
Endress+Hauser confirms successful testing of the device by affixing to it the CE mark.
