AMTROBOX ATEX for zone 22 (Dust)
9
Commissioning
The installation and start--up of the electro--pneumatic actuators must be according to the best safety practices and
mainly:
Piping
:
Starting--up of a new installation requires cleaning the piping by air before connection to the actuator. This will remove any
impurities impossible to eliminate during construction (fillings, flux, paste, PTFE, etc.)
Electric wiring
:
-- The electric components are “CE” marked in accordance with 89/336/EEC and 94/9/EC european directives.
-- The electric supply voltage and the electric values of the signals must be checked before connecting the components.
-- An external earth terminal allows grounding of the metal parts of the control box.
Never uncouple or disassemble the AMTROBOX or its accessories when pressurized or energized.
Make sure to disconnect electrical cables before dismantling.
During the mounting and dismantling of the boxes, take care the correct installation of all sealing gaskets.
Quality and integrity depends of this correct installation.
During workshop or on- site checking, the valve associated with the actuator and its AMTRONIC EEx- ia box can
be operated from full open to full closed position.
This operation may be of a high significant risk of personnal injury if the safety steps required are not taken to
prevent access between the disc and the seat.
CAUTION !
WARNING
Never exceed the values stipulated in this leaflet!
The dust thickness on the box must not exceed 5 mm.
Do not open the box in dust atmosphere.
Do not clean using a compressed air gun to avoid sending dust in the atmosphere.
To remove dust, use a duster a little bit damp.
Electric connections
The electric connection is obtained via 2 packing--gland M20, plastic (for wire dia. 6 to 12) or stainless steel (for wire dia. 7 to 12) or a
Binder connector.
The good tightness of the box depends on cable selection and the tightening level of the packing--gland.
Pneumatic connection
The pneumatic connection is done directly on the actuator or on the solenoid valve fittedon the actuator.
