Pay attention to any liquid leaking out, for this points to a diaphragm
damage.
Check the diaphragm visually for any damage (D-11-9).
Use the pressure transmitter only if the diaphragm is undamaged.
Use the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned.

Remove the protection cap only just before installation and absolutely avoid any
damage to the diaphragm during installation as well (D-10-9).
For Model D-10-9 you have to provide for a sealing element; exceptions are instru-
ments with self-sealing threads (e.g. NPT thread).
For Model D-11-9 the sealing ring is included in delivery.

Connect the instrument to earth via the pressure connection.
Operate the pressure transmitter with a shielded cable and earth the shield at least on
one side of the cable.
This equipment of protection class 3 is designed for connection to safety low voltages
that are separated from the mains voltage or from a voltage greater than AC 50 V or
DC 120 V. It is preferred to connect it to SELV or PELV electric circuits; alternatively, a
safety measure from HD 60346-4-41 (DIN VDE 0100-410) is recommended.
Alternative for North America: The connection may also be made to „Class 2 Circuits“
or „Class 2 Power Units“ according to CEC (Canadian Electrical Code) or NEC (Nati-
onal Electrical Code).
Ingress protection per IEC 60529 (The ingress protection classes specified only apply
while the pressure transmitter is connected with female connectors that provide the
corresponding ingress protection).

Please refer to our data sheet “Pressure gauge sealing washers AC 09.08” in WIKA’s
product catalog Pressure and Temperature Measurement or our website
www.wika.de for details about sealing washers.
When mounting the instrument, ensure that the sealing faces of the instrument and
the measuring point are clean and undamaged.
Screw in or unscrew the instrument only via the flats using a suitable tool and the
prescribed torque. The appropriate torque depends on the dimension of the pressure
connection and on the sealing element used (form/material). Do not use the case as
working surface for screwing in or unscrewing the instrument.
When screwing the transmitter in, ensure that the threads are not jammed.

Diaphragm test for your safety
It is necessary that before starting the pressure transmitter you test the diaphragm visually, as
this is a
safety-relevant component.
