3 Electrical connection
As far as the electrical installation of
the device is concerned, the relevant
national regulations governing the
installation of electrical equipment
and the national accident prevention
regulations of the country of destina-
tion must be adhered to. In Ger-
many, these are the VDE regulations
and accident prevention regulations
of the employer's liability insurance.
For assembly and installation in haz-
ardous areas, the following stand-
ards apply: EN 60079-14: 1997;
VDE 0165 Part 1/8.98 "Electrical
apparatus for explosive gas areas"
and EN 50281-1-2: VDE 0165 Part
2/11.99 "Electrical apparatus for use
in the presence of combustible dust."
For intrinsically safe electrical ap-
paratus that are certified according
to the Directive 79/196/EEC, the
data specified in the certificate of
conformity apply for connection of
intrinsically safe circuits.
For intrinsically safe electrical ap-
paratus that are certified according
to the Directive 94/9/EC, the data
specified in the EC type examination
certificate apply for connection of in-
trinsically safe circuits.
Note: It is absolutely necessary to
keep to the terminal plan specified
in the certificate. Reversal of the elec-
trical connections may cause the ex-
plosion protection to be ineffective!
Do not tamper with screws inside or
on the case which have been sealed
with paint.

Note on the selection of cables and wires:
To run several intrinsically safe circuits in a
multi-core cable, read paragraph 12 of EN
60079-14; VDE 0165/8.98.
For generally used insulating materials, for
example polyethylene, the radial thickness
of the conductor insulation has to be at least
0.2 mm.
The diameter of a single wire in a flexible
conductor shall not be smaller than 0.1 mm.
The conductor ends are to be protected
from unlaying, e.g. by using wire end fer-
rules.
