Safety 13
DANGER!
The connection of non intrinsically-safe or non-
associated equipment presents a risk of explosion!
Operating the EK280 in zone 1 and connecting devices
which are not certified as "associated equipment" present a
risk of explosion.
Therefore:
– When using the EK280 in zone 1, it should only be con-
nected to certified associated equipment as per the
ATEX Product Directive 94/9/EC.
– The EK280 should only be connected to the intrinsically-
safe circuits of associated equipment whose electrical
data corresponds to those requirements stipulated in the
declaration of conformity for the EK280 (see Appendix).
Using incorrect batteries presents a risk of explosion!
Connect only the prescribed Elster battery-types to the de-
vice (see chapter 9.1.4 .)
When connecting and operating the EK280 in explosive gas
atmospheres, the corresponding standards must be ob-
served:
DIN EN 60079-0
DIN EN 60079-14
The device may only be used in zone 1 or zone 2, if instal-
lation has been carried out according to the separate re-
quirements stipulated under DIN EN 60079-14 and the op-
erating conditions (see "Technical Data" chapter) as well as
the connection conditions (see "Assembly, Connection and
Putting into Operation" chapter).
The device may be dangerous if unqualified personnel use it incorrectly or
do not use it according to its intended purpose.
All of those persons who are charged performing works on or with the
device, must have read and understood the manual before commencing
such works. This shall also apply if the person in question has already
worked with the same or a similar device or has been trained by the
manufacturer.
