All operations described in this instruction manual have to be carried out by trained
personnel or by an accredited person only. Installation, commissioning, operation and
maintenance of the capacitive level sensors has to be carried out in accordance with this
instruction manual; the provisions of regulations in force regarding the installation of
electrical equipment have to be adhered to.
Improper use, installation or set-up of the sensor can lead to crashes in the application,
(overlling of the tank or damage of system components).
The manufacturer is not responsible for improper use, loss of work caused by either
direct or indirect damage, and for expenses incurred at the time of installation or during
the period of use of the level sensors.

Packing,transPortation and storage
uipment  is paced in a polythene bag and the whole consignment is placed in a card-
board bo. The cardboard bo is suitably lled to prevent mechanical damage during transport. et
the device paced up till the use to prevent possible damage.
Transport to the customer is realied by forwarding company. pon receipt please chec whether
the shipment is complete and corresponds to the etent of the order or whether during the transport
did not occurred the damage of the pacaging or the euipment. The device apparently damaged
during transport do not use and contact the manufacturer to resolve the situation.
f the device is transported further then only wrapped in the original pacaging and protected
against shocs and weather. tore the device in its original pacaging in a dry place sheltered from
the weather with humidity up to  without the effects of chemically active substances. torage
temperature range is from   to  .
Sensor variants CLS–23_–20 a 21 with the electrodes longer than 100 mm are tted with
protective caps at the ends of the electrodes to prevent damage of the electrodes, box
rupture or injury of handling persons. Before commissioning, remove the caps.
