hazardous areas, whereby special attention must be paid to maintain separation distances
to all non-intrinsically safe circuits according to the requirements in IEC/EN 60079-14.
All separation distances between two adjacent intrinsically safe circuits need to be observed
in accordance with IEC/EN 60079-14.
If "Ex i" protected circuits (intrinsically safe) were operated with non-intrinsically safe
circuits, they must no longer be used as "Ex i" protected circuits.
The respective peak values of the field device and the associated apparatus with regard to
explosion protection should be considered when connecting intrinsically safe field devices
with intrinsically safe circuits of associated apparatus (verification of intrinsic safety).
Make sure to observe IEC/EN 60079-14 and IEC/EN 60079-25.
If more channels of one device are connected in parallel, make sure the parallel connection
is made directly at the terminals of the device. When verifying the intrinsic safety, the
maximum values for the parallel connection must be considered.
1.7 Operation, Maintenance, Repair
The devices must not be repaired, changed or manipulated. If there is a defect, the product
must always be replaced with an original device.
1.8 Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the ones you ordered.
Keep the original packaging. Always store and transport the device in the original
packaging.
Always store the device in a clean and dry environment. The permitted storage temperature
(see technical Information TI00429F) must be considered.
Disposing of devices, packaging material, and possibly contained batteries must be in
