2. Safety
2.4 Special hazards
WARNING!
Observe the information given in the applicable type examination certifi-
cate and the relevant country-specific regulations for installation and use
in hazardous areas (e.g. IEC 60079-14, NEC, CEC). Non-observance can
result in serious injury and/or damage to equipment.
For additional important safety instructions for instruments with ATEX
approval see chapter 2.3 "Additional safety instructions for instruments per
ATEX".
WARNING!
■
Only connect or disconnect the CPG1000 once the system has been
depressurised!
■
Observe the working conditions in accordance with chapter 3 "Specifi-
cations".
■
Always operate the pressure indicator within its overpressure limits.
■
For hazardous media such as oxygen, acetylene, flammable or toxic
gases or liquids, and refrigeration plants, compressors, etc., in addition
to all standard regulations, the appropriate existing codes or regulations
must also be followed.
■
If it is obvious that safe operation of the instrument is no longer possi-
ble, the instrument must be put out of operation and marked in order to
secure it against inadvertent use.
■
The circuitry for connection to other devices should be designed with
particular care. Under certain circumstances internal junctions in exter-
nal devices (e.g. GND junctions with screen) could lead to impermissi-
ble voltage potentials that could impair the function of the device itself or
a device connected to it, or even destroy them.
■
The measurement signal of the reference (or test sample) can be influ-
enced by massive electromagnetic irradiation and/or the indication of
the signal could be completely absent.
■
If the CPG1000 is used in applications with oil as a pressure medium,
make sure it will not be used with flammable material or gases directly
afterwards since it can lead to dangerous explosions and danger to
personnel and machinery.
■
Residual media in the dismounted instrument can result in a risk to
persons, the environment and the equipment. Take sufficient precaution-
ary measures.
