CAUTION
Special conditions for use:
1.For IIC Ga uses the pressure switches have to be installed and used in such a way, that electrostatic
charging from operation, maintenance and cleaning is excluded.
For IIIC Da uses process-related electrostatic charges, e.g. due to passing media have to be excluded
for pressure switches containing non-metallic parts.
2.Metallic parts have to be included in the local potential equalization.
3.The intrinsically safe supply is connected to the ground potential for safety reasons. Potential
equalization has to exist in the entire area of the installation of the intrinsically safe circuit.
4.For the uses in areas that require EPL Ga the devices have to be installed in such a way, that ignition
hazard due to impact or friction can be excluded.
CAUTION
No inadmissible heating can be expected that affect the maximum surface temperature. The maximum
surface temperature lies only a small amount above the permissible ambient temperature during
operation.

CAUTION
Special conditions for use:
1.The size of the nameplate exceeds the permissible area and can therefore be electrostatically
charged:
For IIC Ga uses the pressure switches have to be installed and used in such a way, that
electrostatic

operation,
For the use in explosive dust atmospheres process-related electrostatic charges, e.g. due to
passing media have to be excluded.
2.All metallic parts of the devices have to be included in the local potential equalization.
3.The intrinsically safe circuit of the device is connected to the earth potential, therefore potential
equalization has to exist in the entire area of the installation of the intrinsically safe circuit.
4.The housings of the devices consist of more than 10% aluminum, therefore in EPL Ga applications
the installation has to be carried out in such a way, that ignition hazard due to impact or friction
can be excluded.
CAUTION
No inadmissible heating can be expected that affect the maximum surface temperature. The maximum
surface temperature lies only a small amount above the permissible ambient temperature during
operation.
