Using the wrong model presents a risk of explosion!
The EK280 is available in different models for use in zones
1 and 2.
The model designed for zone 2 should not be used in zone
1 as this presents a risk of explosion!
Therefore:
– Before installing the device in zone 1, please check that
the EK280 is suitable for use in zone 1.
– The EK280 should only be operated in zone 1, if cate-
gory "II 1 G" or "II 2 G" have been marked on the ATEX
label.
– If category "II 3 G" has been marked on the ATEX label,
the EK280 should not be used in zone 1, but only in
zone 2.
– The ATEX label is located on the top panel of the
EK280 housing.
The following solely applies for the EK280 model with integrated
power supply unit (ATEX category "II 3 G" for use in zone 2):
– Do not open when an explosive atmosphere may be pre-
sent!
– Electrostatic hazard: Do not rub!
The EK280 can either be mounted on a gas meter, on a pipe-
line, or on a wall.
Should problems arise during assembly, e.g. with regard to
the selection of suitable assembly tools, please contact our
customer service team (see "General" chapter).
