The following inspection criteria must be observed
:
Use and electrical connection of actuators in areas
subject to explosion hazards
Only ATEX-approved electrical equipment according to ATEX Di-
rective 2014/34/EU for device group II as well as device catego-
ry 2 for zones 1 and 21 and device category 3 for zone 2 and 22,
such as actuators, terminal boxes and thermocouples as speci-
fied by SCHAKO may be used for devices from SCHAKO KG.
For the technical data and connection diagrams, please refer to
the technical documentation.
The connection lines must be installed for permanent use and in
such a way that they are sufficiently protected from mechanical
and thermal damage.
Devices with explosion-protected drives and terminal boxes
have to be attached over the external potential connecting termi-
nal to the potential equalisation provided by the customer with
at least 4 mm² cooper solid-core.
The electrical connection lines of the actuators must be con-
nected in a terminal box according to ATEX Directive 2014/34/
EU for device group II as well as device category 2 for zones 1
and 21 and device category 3 for zones 2 and 22 if the electrical
connection is made in the area subject to explosion hazards.
The dimensioning of the conductor cross-sections must be ob-
served.
The actuators are maintenance-free with respect to their func-
tion, but the relevant maintenance regulations according to
ATEX directives or factory regulations must be observed.
