2. Safety
WARNING!
Before installation, commissioning and operation, ensure that the appropriate level switch
has been selected in terms of measuring range, design and specic measuring conditions.
Non-observance can result in serious injury and/or damage to the equipment.
WARNING!
Observe the working conditions in accordance with Chapter 3 "Specications".
Further important safety instructions can be found in the individual chapters of these
operating instructions.
2.1 Intended use
The level switch is used to convert a level into an electrical signal indoors and outdoors.
The level switch has been designed and built solely for the intended use described here, and may only
be used accordingly.
The technical specications contained in these operating instructions must be observed. Improper
handling or operation of the level switch outside of its technical specications requires the instrument to
be taken out of service immediately and inspected by an authorised WIKA service engineer.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended
use.

2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
Improper handling can result in considerable injury and damage to equipment.
The activities described in these operating instructions may only be carried out by skilled
personnel who have the qualications described below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training, knowledge
of measurement and control technology and on their experience and knowledge of country-specic
regulations, current standards and directives, are capable of carrying out the work described and
independently recognising potential hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
2.3 Special hazards
WARNING!
For hazardous media, in addition to all standard regulations, the appropriate existing codes
or regulations must also be followed.
WARNING!
Residual media in dismounted level switches can result in a risk to persons, the
environment and equipment.
Take sucient precautionary measures.
CAUTION!
Operate the level switch only at a minimum distance of 1 m from electromagnetic elds.
