2.4 Risks of Use
The housing is made of polycarbonate. On the top lid is placed foil keyboard made of polyester. In
some extreme cases, electrostatic charges may build up on the cabinet surface. Its energy could
cause the initial explosive atmosphere to initialize.
Here are recommendations to avoid the risk of ignition due to electrostatic charges:
If the device is used in a potentially explosive atmosphere, it must not be installed in a
place where external conditions may cause electrostatic charges.
The device may only be cleaned with a damp cloth.
It is also necessary to observe:
the cables must be tightly tightened in the cable glands against pulling out
the device must not be opened if there is an explosive atmosphere
the enclosure must not be damaged
2.5 Connecting of external devices
ATTENTION!
In terms of safety, the device is equipped with connection terminals with
two types of signals:
- terminals with intrinsically safe signals
- terminals with signals with protection “nA”
The terminals of intrinsically safe device can be connected only approved
devices (intrinsically safe device associated apparatus) or so. Simple
devices complying with the standard EN 60079-11 and complying with the
intrinsically safe parameters mentioned in paragraph in the EU Examination
Certificate Type[16].
Terminals with “nA” protected signals can be connected to standard
equipment that meets operating parameters. When connecting wires to
these terminals, it must be non-energized conductor.
The relevant safety standards must be observed when wiring.
The electrical connection
of external devices to the ELCOR
plus
for Zone 2 is described in
paragraph 8 of this Annex.
The designation of intrinsically safe and "nA" terminals
is described in paragraph 8.1 of this
Annex.
The connection of the device must be carried out in accordance with the applicable norms and
standards, in particular:
EN 60079-14 - Explosive atmospheres - Part 14: Design, selection and installation of electrical
installations,
EN 60079-25 - Explosive atmospheres - Part 25: Intrinsically safe electrical systems,
EN 60079-0 - Electrical apparatus for explosive gas atmospheres - Part 0: General requirements,
EN 60079-11 - Explosive atmospheres - Part 11: Protection of equipment by intrinsic safety "i",
EN 60079-15 - Explosive atmospheres - Part 15: Equipment protected by type of protection 'n'
