1 Safety instructions

1.1 Designated use

The Liquicap M FTI51 and FTI52 are compact capacitive level measuring devices for level limit

detection of liquids.

1.2 Installation, commissioning and operation

The Liquicap M has been safely built with state-of-the-art technology and meets all applicable

standards and EU directives. However, if it is used improperly or if it is not put to its intended use,

it can be a source of application-related dangers, such as product overflow due to incorrect

installation or configuration. Therefore, the installation, electrical connection,commissioning,

operation and maintenance of the measuring device only may be carried out by trained specialist

personnel authorized by the facility's owner/operator for this purpose. The specialist personnel

must have read and understood these Operating Instructions and must follow the instructions they

contain. Modifications or repairs to the device can be carried out only if it is expressly stated in the

Operating Instructions that these are permitted.

1.3 Operational safety

1.3.1 Hazardous areas

If the measuring system is used in hazardous areas, the corresponding national/federal standards

and regulations must be observed. The device is accompanied by separate Ex documentation, which

is an integral part of this documentation. Observe the installation instructions, connection data and

safety instructions provided there.

• Ensure that the specialists are adequately trained.

• Observe the metrological and technical safety requirements for the measuring points.

1.4 Safety conventions and symbols

We have defined the following safety instructions to indicate safety-related or alternative

procedures. Each instruction is identified by a corresponding pictogram.

Safety instructions

#Warning!

This symbol indicates an action or procedure which, if not performed correctly, can result in serious

injury, a safety hazard or the destruction of the device.

"Caution!

This symbol indicates an action or procedure which, if not performed correctly, can result in injury or

destruction of the device.

!Note!

This symbol indicates an action or procedure which, if not performed correctly, can have an indirect

effect on operation or trigger an unexpected response on the part of the device.

Type of protection

0Explosion-protected, prototype-tested apparatus

If this symbol appears on the nameplate of the device, the device can be used in hazardous or non-

hazardous areas according to its approval.

-Hazardous areas

In the drawings in these Operating Instructions, this symbol identifies hazardous areas. Devices

located in hazardous areas and lines for these devices must have corresponding explosion protection.

.Safe areas (non-hazardous areas)

In the drawings in these Operating Instructions, this symbol identifies non-hazardous areas. Devices

in the non-hazardous area also must be certified if the connecting lines lead into the hazardous area.

Electrical symbols

%Direct current

A terminal at which DC voltage is present or through which DC voltage flows.

&Alternating current

A terminal at which AC voltage (sinusoidal) voltage is present or through which AC flows.

)Ground connection

A grounded terminal which, from the viewpoint of the user, is grounded via a grounding system.

*Protective ground connection

A terminal that has to be grounded before other connections can be made.

+Equipotential connection

A connection that has to be connected to the grounding system of the plant. This can be a potential

equalization line or a radial grounding system depending on national and company codes of practice.

Temperature resistance of the connecting cables

Indicates that the connecting cables must be able to withstand temperatures of at least 85 °C.
