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 potentially explosive atmospheres (e.g. IEC 60 079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to equipment.
For additional important safety instructions for insturments with ATEX
approval see chapter "2.3 Additional safety instructions for instruments
with ATEX approval".
WARNING!
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.
DANGER!
Danger of death caused by electric current
Operation using a defective power supply unit (e.g. short circuit from
■
the mains voltage to the output voltage) can result in life-threatening
voltages at the instrument!
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.
