1.5 General Safety Information
Responsibility for planning, assembly, commissioning, operation, maintenance,
and dismounting lies with the plant operator.
Installation and commissioning of all devices may be performed only by trained and qualified
personnel.
It is dangerous for the user to make changes and/or repairs. Additionally, doing so voids the
warranty and excludes the manufacturer from any liability. In the event of any serious errors,
stop using the device. Secure the device against unintended operation. To have the device
repaired, return it to your local Pepperl+Fuchs representative or your sales center.
Warning!
Risk of fire due to improper use.
Damaged or faulty lithium-ion batteries are a major fire hazard. Ensure that the battery is pro-
tected from mechanical damage, short circuits, and excessive heat load during servicing and
while the wireless ultrasonic sensor is in operation. The permissible ambient temperatures from
-25 °C to +70 °C and the permissible storage temperatures from -40 °C to +85 °C must always
be observed. The device enclosure and ultrasonic sensor enclosure comply with flammability
class V-0(AO) according to IEC 60695-11-10 and therefore must not be operated in areas with
an automatic extinguishing system. Devices with damaged batteries must be removed immedi-
ately, taken out of operation, and stored safely in accordance with local fire prevention regula-
tions.
Warning!
Risk of injury if battery is faulty!
This device uses a high-energy cell for its voltage supply. This battery contains lithium and thi-
onyl chloride. If these substances are released, the appropriate protective measures must be
observed. Refer to the safety datasheet.
In case of leakage, contact with the skin or eyes may cause severe irritation and burns. Inhala-
tion of electrolyte vapors may affect the upper respiratory tract and lungs.
Note
The safety datasheet for lithium thionyl chloride batteries can be found online at www.pepperl-
fuchs.com, on the product detail page for the respective WS-UC*-F406-B41-* wireless
ultrasonic sensor under "Documents."
Caution!
Risk of unauthorized sensor access due to unprotected access data.
To use and operate the WILSEN.sonic.distance wireless ultrasonic sensor safely, access data
such as passwords and the application key must be protected. The plant operator is responsi-
ble for protecting this data; the operator must document the access data, protect it from unau-
thorized access, and keep it safe.
Note
Disposal
Electronic waste is dangerous. When disposing of the equipment, observe the current statutory
requirements in the relevant country of use and local regulations.
