Safety instructions
6.6 Safety instructions for electrical equipment in
hazardous areas
• The MemoLink must never be used in hazardous areas! The MemoLink is
not designed as a field device for installation in industrial environments.
• The MemoLink, which is approved in accordance with EU
type-examination certificate BVS 12 ATEX 079 X, ensures that the
"intrinsic safety" protection type of the Memosens measuring cable and the
Memosens sensor are not compromised during calibration and functional
testing.
The relevant EU Declaration of Conformity is an integral part of this
document.
• The device computers, USB cable, MemoLink, Memosens measuring cable
and Memosens sensor must be located outside the hazardous area during
calibration and functional testing.
• Memosens cables with Memosens sensors may be connected to the
Memosens interface of the Memolink.
• The internal electronics of the Ex-approved Memosens/USB interface
converter MemoLink allow the connection of Ex-approved and
non-Ex-approved passive Memosens measuring cables with Memosens
sensors. The connection of non-Ex-approved Memosens sensors does not
interfere with the intrinsic safety of Ex-approved Memosens sensors
connected at a later stage.
• MemoLink may only be connected to the USB interface of a commercially
available computer.
