WARNING
-
The technical data as set out in the EC type examination certificate are authorita-
tive. Should you not have the current certificate, please request it from us or
download it from our website at http://www.bdsensors.de.
-
Working on live components, with the exception of intrinsically safe circuits, is
strictly prohibited whenever there is any risk of explosion!
-
Make sure that there is equipotential bonding along the entire length of the line,
both inside and outside the explosion hazard area.
-
If there is an elevated risk of the device being damaged by lightning strikes or power
surges, greater lightning protection must also be provided.
-
Pay attention to the limit values set out in the EC type examination certificate. (The
capacitance and inductance of the connecting cable are not included in the values.)
-
Make sure that the entire system of interconnected intrinsically safe components
remains intrinsically safe. The operator is responsible for the intrinsic safety of the
overall system (the circuit as a whole).
-
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 re-
tain any protective cap supplied!
Danger of death from electric shock or
explosion
Disconnect the device from the power supply.
-
Install equipotential bonding along the entire
-
length of the line, both inside and outside the
explosion hazard area.
Do not install the device while there is a risk
-
of explosion.
Danger of injury from media escaping under
pressure
Install in an unpressurised state.
-
Depressurise the system.
