4.1 Installation and safety instructions
WARNING
-
In case of increased danger of lightning strike or damage by overvoltage, a stronger
lightning protection should be planned.
-
Do not install the device in a pneumatic delivery stream!
-
Excessive dust accumulations (over 5 mm) or complete coverage with dust must be
prevented!
-
A minimum of protection class IP 20 must be ensured for the electrical installation.
Please treat this highly sensitive electronic measuring instrument carefully, both
when packed and when unpacked!
No modifications or alterations may be made to the device.
The device must not be thrown!
Only remove the packaging and, if applicable, the protective cap from the device
shortly before its installation, so as to avoid damaging the diaphragm. Be sure to
retain any protective cap supplied!
Fit the protective cap back over the diaphragm immediately after dismounting the
device.
Treat the unprotected diaphragm with extreme care; it can be damaged very easily.
Do not apply any force to install the device so as to avoid damaging the device and
the system!
When installing outdoors or in humid environments, the following points should be
noted:
-
The device should be electrically connected immediately after installation to ensure
that no moisture is able to penetrate into the plug connector, If this is not possible,
the ingress of moisture must be prevented by using a suitable protective cap. (The
protection class specified in the data sheet applies to the connected device.)
-
Select an installation position that allows splashed water and condensation to drain
away. Ensure that sealing surfaces are not exposed to standing liquid!
-
When using devices with a cable outlet, the outgoing cable should be routed
downwards. If the line must be routed upwards, this is to be achieved by bending it
through a downward-pointing arc.
-
Install the device such that it is protected from direct sunlight. Direct exposure to
sunlight may, in the worst case, cause the maximum permissible operating
temperature to be exceeded.
When the device is connected to the pressure chamber, the user much ensure
proper sealing.
Check that the envisaged or, if applicable, supplied seals are compatible with the
medium used. If it is not possible to guarantee compatibility, other suitable seals
must be employed.
Danger of injury from media escaping under
pressure
Install in an unpressurised state.
-
Depressurise the system.
