Notes on Safety
Approved usage
The Cerabar S is a pressure transmitter used for measuring gauge or absolute pressure
depending on the version. You can display the measured pressure value as a level value
using the Commuwin II operating and display program or using the handheld operating
terminals for HART or INTENSOR.
Mounting,
commissioning,
operation
The Cerabar S has been designed to operate safely in accordance with current technical,
safety and EU standards. If installed incorrectly or used for applications for which it is
not intended, however, it is possible that application-related dangers may arise, e.g.
product overspill by incorrect installation or adjustment. For this reason, the instrument
must be installed, connected, operated and maintained by personnel that are authorised
by the user of the facility and who are suitably qualified. The manual must have been
read and understood, and the instructions followed. Modifications and repairs to the
device are permissible only when they are expressly approved in the manual. Pay
attention to the technical data on the nameplate.
Explosion hazardous

Instructions listed in this document must be observed. The certificates are designated
by the first letter of the order code on the nameplate (see table below).
