2.2 ATEX approved execution
WARNING
* The ATEX ame proof certied EL electric actuator
is a Group II category 2 equipment and intended
for use in areas in which explosive atmospheres
caused by mixtures of air and gases, vapors or
mists are likely to occur.
Therefore the ATEX ame proof certied electric
actuator may be used in (ATEX) classied Zones 1
& 2 (Gases)
2.3 ATEX Installation instructions
1 The cable entry device and the closing elements of
unused apertures must be of a certied ameproof
type, suitable for the conditions of use and correctly
installed.
2 Heat resistant cable and cable glands shall be
used, suitable for temperatures of at least 130°C.
3 When the EL actuator is connected to a separate
source of heating or cooling, such as a heated or
cooled process vessel or pipeline, the temperature
transfer should not cause the actuator to exceed the
specied ambient temperature range (Tamb = -20
°C ... +60 °C).
4 Wiring dimensions for external earth connection is
4mm² (12 AWG), for internal earth connection max.
2.5mm² (22-12AWG)
5 Blind plugs or cable gland shall be engaged into the
cable entries minimal 5 threads.
6 When replacing cover screws, use cover screws
according ISO 3506 with property class A2-70.
