Installation in explosive atmospheres, installation zones 1 und 2

Danger!
The same functional and design characteristics apply to the maintenance instructions for the
use of SCPs in potentially explosive atmospheres as described in the respective applicable
operating manual.
In addition to this, the following extensions apply:
1. All components relevant for the use of SCPs in relation to their use in potentially explosive
atmospheres (concerns both electrical and non-electrical components) are separately
designed and documented – see product description!
2. Extension to the method of working
The use of SCPs is extended to use in potentially explosive atmospheres, including the
compression of process gases (only compression for the purposes of pressure increase).
The SCPs are not suitable for pumping potentially explosive mixtures. This means, when
the compressor is in intake condition, the pumped liquid must not contain any oxygen.
The intake condition always refers to pressure layers in the overpressure range.
The owner operator and the system builder must use monitoring devices reflecting the
respective state of the art standards, to positively monitor and ensure this effect.
3. Safety equipment extension
If oil heaters are used in potentially explosive atmospheres (see also component specifi-
cations in the product description) additional, separate oil level monitoring is absolutely
necessary to ensure a minimum oil level above the heating elements. To this end, a sepa-
rate oil level switch is used in each use case according to the necessary explosion protec-
tion specifications – see also the component specifications in the product description.
