6. Packaging / 7. Starting, operation
Inspect the pressure transmitter for possible damage during transportation. Should
there be any obvious damage, inform the transport company and WIKA without delay.
Keep the packaging, as it offers optimal protection during transportation (e.g. chan-
ging installation location, shipment for repair).
Ensure that the pressure connection thread and the connection contacts will not be
damaged.
7. Starting, operation
Required tools: wrench (flats 19), screw driver
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.
Pay attention to any liquid leaking out, for this points to a diaphragm
!
damage.
Use the pressure transmitter only if the diaphragm is undamaged.
Warning
Use the pressure transmitter only if it is in a faultless condition as far as the
safety-relevant features are concerned.

7. Starting, operation
You have to provide for a sealing element; exceptions are instruments with self-
sealing threads (e.g. NPT thread).
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.

Electrical connection
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, if the cable is longer than 30m (2-wire) or 3m (3- or 4-wire), or if
it is run outside of the building.
Use power supplies which guarantee reliable electrical isolation of the operating
voltage as per IEC/DIN EN 60204-1. Consider also the general requirements for PELV
circuits in accordance with IEC/DIN EN 60204-1.
The connection may also be made to „Class 2 Circuits" or „Class 2 Power Units"
according to CEC (Canadian Electrical Code) or NEC (National 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).
Ensure that the cable diameter you select fits to the cable gland of the connector.
Ensure that the cable gland of the mounted connector is positioned correctly and
that the sealings are available and undamaged. Tighten the threaded connection and
check the correct position of the sealings in order to ensure the ingress protection.
