1. General information
1.1 Hazard statements
The symbols and hazard statements below may appear in Grundfos
installation and operating instructions, safety instructions and service
instructions.
The hazard statements are structured in the following way:
DANGER
Indicates a hazardous situation which, if not avoided, will result in
death or serious personal injury.
WARNING
Indicates a hazardous situation which, if not avoided, could result
in death or serious personal injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result
in minor or moderate personal injury.
SIGNAL WORD
Description of hazard
Consequence of ignoring the warning.
- Action to avoid the hazard.
English (GB)

1.2 Notes
The symbols and notes below may appear in Grundfos installation and
operating instructions, safety instructions and service instructions.
2. Receiving the product
On receipt of the product, do the following:
1. Check that the product is as ordered.
If the product is not as ordered, contact the supplier.
2. Check that no visible parts have been damaged.
If any visible parts have been damaged, contact the transport company.
Observe these instructions for explosion-proof products.
A blue or grey circle with a white graphical symbol indicates that
an action must be taken.
A red or grey circle with a diagonal bar, possibly with a black
graphical symbol, indicates that an action must not be taken or
must be stopped.
If these instructions are not observed, it may result in malfunction
or damage to the equipment.
Tips and advice that make the work easier.
The membrane at the process connection of the level transmitter
must not come into contact with sharp or hard objects or be
damaged since it may result in incorrect measurements or even
media leakage.
English (GB)

3. Installing the product
DANGER
Explosive environment
Death or serious personal injury
- The products in these installation instructions are not intended
for use in potentially explosive areas.
CAUTION
Electric shock
Minor or moderate personal injury
- Install the product in a currentless condition.
The level transmitter must be grounded. To prevent electrolysis,
the shielding of the level transmitter must be set to the same
potential as the products usually found in the medium, such as
pumps and agitators.
The special cable for the level transmitter must be fitted so that the
pressure compensation in the cable assembly is not crushed. The
cable end must terminate in a dry room or in a suitable terminal
case so that no moisture can get through. In addition, the cable
must not be routed through damp conditions.
For variations in media, a guide tube must be used to prevent
measuring errors in flow caused by sideways movement and by
hitting the level transmitter against the walls of the container.
We recommend using a terminal case with a pressure
compensation element. See section 5.4.2 Terminal case with
pressure compensation element. The terminal case must be
mounted as close as possible to the surface of the medium while
still outside the medium.
The membrane at the process connection of the level transmitter
must not be damaged, otherwise it may result in incorrect
measurements or even media leakage. The membrane must not
come into contact with sharp or hard objects.

Level transmitters in free-field applications without integrated
overvoltage protection must be protected against electrical
discharge. In addition, we recommend using external overvoltage
protection upstream and downstream of the display or processing
unit.

4. Storing the product
The products must be stored in dry, clean conditions and protected against
external and mechanical damage.
The storage temperatures can be found in the technical data. See section
8. Technical data.
5. Product introduction
5.1 Intended use
Level transmitters are used to carry out hydrostatic level measurements in
ventilated tanks or to gauge water levels in open waters. They are designed
to hang vertically from the cable.
The correct level transmitter should be selected with regard to the measuring
range, version and specific measuring conditions on site before mounting,
installation and startup. The specifications provided by the manufacturer are
intended as suggestions only, except those relating to the test series. The
decision is to be made by the operator.
The manufacturer cannot accept liability for damage resulting from improper
use or in the event of use contrary to the intended purpose.
To prevent damage to the level transmitter and to safeguard its process,
mounting, installation and startup must only be performed by qualified
personnel. Personnel must be familiar with local regulations and be aware of
applied standards and directives to prevent bodily injuries and material
damage.
5.2 Pumped liquid
The PE-LD cable is shielded and suitable for use in water such as lake,
water well, and mine water. The cable is UV-resistant.
The FEP cable is shielded and suitable for use in water such as sea, lake,
water well, and mine water as well in different oils, fuels, and solvents. The
cable is UV-resistant.
The EPR cable is a submersible motor cable.

5.4 Accessories
5.4.1 Cable clamp
The cable clamp, part no. 99488578, holds the level transmitter in the liquid
at a defined depth and provides strain relief. Use of the cable clamp ensures
that the cable is not deformed.
The cable clamp is compatible with level transmitters with a cable diameter
of 5.5 to 10.5 mm. The maximum tensile strength is 2.5 kN. The case is
made of hot-dip galvanised steel sheets. The clamping jaws and guide clips
are made of fiberglass-reinforced polyamide.
Fig. 4 Cable clamp
5.4.2 Terminal case with pressure compensation element
The terminal case, part no. 99488577, is used for secure installation of the
level transmitter cable. The end of the pressure equalisation hose is always
protected from deposits and condensation (IP65). The remaining distribution
can be performed with a standard cable without a pressure equalisation
hose.
The terminal case must be mounted as close as possible to the medium
surface while still outside the medium to ensure the system is implemented
cost-effectively and in the best possible way.
