3. Target Group, Personnel
Responsibility for planning, assembly, commissioning, operation,
maintenance, and dismounting lies with the plant operator.
The personnel must be appropriately trained and qualified in order to carry
out mounting, installation, commissioning, operation, maintenance, and
dismounting of the device. The trained and qualified personnel must have
read and understood the instruction manual.
Prior to using the product make yourself familiar with it. Read the
instruction manual carefully.
4. Reference to Further Documentation
Observe directives, standards, and national laws applicable to the
intended use and the operating location.
The corresponding datasheets, manuals, declarations of conformity, EU-
type examination certificates, certificates, control drawings, and
temperature tables if applicable are an integral part of this document. You
can find this information under www.pepperl-fuchs.com.
For specific device information such as the year of construction,
scan the QR code on the device. As an alternative, enter the serial number
in the serial number search at www.pepperl-fuchs.com.
Refer to the relevant EU-type examination certificate to see the
relationship between the connected circuit type, the maximum permitted
ambient temperature, the temperature class, and the effective inner
reactances.
5. Intended Use
The device is only approved for appropriate and intended use.
Ignoring these instructions will void any warranty and absolve
the manufacturer from any liability.
The level probe is a hydrostatic pressure sensor for measuring the level
in liquids.
Use the device only within the specified ambient and operating conditions.
Only use the device in media to which the process-contacting materials
of the device are sufficiently resistant.
The EU-type examination certificate in accordance with ATEX Directive
applies only to the use of apparatus under atmospheric conditions.
DOCT-5522B / 2025-01
The device is an intrinsically safe apparatus according to
IEC/EN 60079-11.
The device can be used in hazardous areas containing gas, vapor, and
mist.
6. Improper Use
Protection of the personnel and the plant is not ensured if the device
is not used according to its intended use.
7. Mounting and Installation
Use appropriate protection measures in order to protect persons that have
contact with hazardous or toxic substances.
Do not mount a damaged or polluted device.
Mount the device in a way that the device is protected against mechanical
hazard.
If you expect dynamic loads, support the extension tube of the device.
Secure the device against swinging.
Only use accessories specified by the manufacturer.
Avoid impact effect or friction during mounting.
Optional Avoid inadmissibly high electrostatic charge plastic surfaces.
specifications
Avoid inadmissibly high electrostatic charge of insulated capacities or
insulated metal parts.
–
Regarding the verification of intrinsic safety, observe the maximum
permissible external capacitance of this device and the other devices in
the circuit.
The level of protection is determined by the connected intrinsically safe
circuit.
Use a terminal box for connection.
Requirements for Cables and Connection Lines
Only use cables and connection lines with a temperature range
appropriate to the application.
Install cables and cable glands in a way that they are not exposed to
mechanical hazards.
Observe the minimum bending radius of the conductors.
Observe the permissible core cross section of the conductor.
Crimp wire end ferrules on the conductor ends.
Only use cables and connection lines with an appropriate insulation.
When installing the conductors the insulation must reach
up to the terminal.
Ensure that insulation of the cables and connection lines is not damaged.
Ground the shield according to the requirements.
Close all unused cable glands with the appropriate sealing plugs.
Requirements for Hazardous Area
When connecting intrinsically safe devices with intrinsically safe circuits of
associated apparatus, observe the maximum peak values with regard to
explosion protection (verification of intrinsic safety). Observe the
standards IEC/EN 60079-14 or IEC/EN 60079-25.
For intrinsically safe circuits, the dielectric strength of the insulation against
other intrinsically safe circuits and against the shield must be
at least 500 V according to IEC/EN 60079-14.
Refer to the temperature tables for the relationship between permitted
ambient temperature, range of application and temperature class.
The device may be installed in Zone 1.
If circuits with type of protection Ex i are operated with non-intrinsically
safe circuits, they must no longer be used as circuits with type of
protection Ex i.
8. Operation, Maintenance, Repair
Use appropriate protection measures in order to protect persons that have
contact with hazardous or toxic substances.
If you operate the device in safety-related applications, observe the
requirements for functional safety. In case of operating in low demand
mode, plan appropriate intervals for the proof test.
Do not use a damaged or polluted device.
The device is maintenance-free.
Do not repair, modify, or manipulate the device.
If there is a defect, always replace the device with an original device.
Connection or disconnection of energized circuits is only permitted in the
absence of a potentially explosive atmosphere.
Avoid impact effect or friction during operating.
Avoid inadmissibly high electrostatic charge plastic surfaces.
Avoid inadmissibly high electrostatic charge of insulated capacities or
insulated metal parts.
