B.7.3 Electrical Connections
External wires or connections of external ATEX-certied apparatus via the conduit entry
of an additional extension must be wired to the internal cards of the ICON3000, in
accordance with the wiring diagram and general instructions on the actuator label.
B.7.3.1 Connection for Ex-e Terminals Enclosure
The wires must be terminated in accordance with the following method:
Type of terminal: Insulated ring tongue
Eye dimensions: 5.5 mm (0.22 in) for power cable
3.2 mm (0.13 in) for control cables
Recommended tightening torques: 2.0 - 2.8 Nm (17.7 - 24.8 lb.in) for power cables
1.0 - 1.5 Nm (8.9 - 13.3 lb.in) for control cables
Wires section: 4 mm² (0.006 in²) for power cables
2.5 mm² (0.004 in²) for control cables
B.7.4 Cable Connection
When optional extensions for additional entries or additional electronic cards are
connected to external cables or conduits, the sealing of these entries must be carried
out in accordance with the national standards or regulatory authorities that certied
the extension(s). The method of sealing and cable glands used must be approved and
separately certied for use in hazardous areas.
Two earth connection points - one internal and one external - are located on the
ICON3000 base model (see Figure B-8) for connection to ground cables.
NOTICE
To prevent water inltration through the line cable conduits, ensure that the cable glands used
possess the minimum degree of protection required by the plant and are specied on the
actuator label. If a rigid conduit makes a connection to the plant, it is recommended to place a
exible pipe connection between the conduit and the conduit entry of the additional extension.
To guarantee that the weather-proof and explosion-proof characteristics are maintained,
screw the cable gland or the external ATEX-certied apparatus tightly (at least 5 turns of
engagement) and coat them with a thread sealant.
NOTICE
All accessories (including cable glands) must comply with approved specications for the
site requirements and be certied according to the standard directive. When selecting
cables and cable glands, the maximum temperature of the cable (indicated on the
product label of the base ICON3000) must be considered.
