Foreword
The following instructions must be read, among others, together with the Standards EN 60079-17 (Inspection and
maintenance of electrical installations in hazardous areas (other than mines)), EN 60079-14 (Electrical apparatus for
explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)),
EN 60079-19 (Repair
and overhaul for apparatus used in explosive atmospheres), the by-laws, decrees, orders, laws,
directives, implementation circulars, other relevant standards, state of the art and any other document regarding the
relevant installation site. Sammode cannot and will not be liable if these standards are not complied with. The user shall
be fully aware of the electrical hazards as well as the physical and chemical characteristics of the dusts to be found in
the installation. This shall include, among others, the checking of the compatibility between the surface temperatures of
the luminaire and the ignition temperatures of these dusts in particular. The same applies to combustible gas, vapours
or mists.
This luminaire is meant for areas where potentially explosive dust and/or gas atmospheres may be present:
Area 21, Area 2
These area definitions may be as follows:
-
Area 21: Location where an explosive atmosphere, taking the form of a combustible dust cloud in the air, is liable
to occasionally gather under normal operating conditions.
-
Area 2: Location where an explosive atmosphere, taking the form of a combustible gas cloud in the air, is not liable
to gather under normal operating conditions and where, should it occur, it would not be in a frequent way and it
would occur for a short while only.
Determination and delimitation of these areas fall within the responsibility and competence of the person in charge of
the site.
Instructions for a hazard-free installation (to be carried out by trained staff)
1 Installation
Any work on the luminaire should be carried out when voltage is off.
1.1
Position the fixing straps
alone.
1.2 Prior to the installation of the luminaire in its fixing straps :
a) loosen the screw in the middle
,
in order to free the
internal gear tray, the end cap
stays in position,
b) loosen the screw in the middle
,
remove the mobile end
cap
and the gasket
,
c) pull the internal gear tray out of the luminaire, and fit
mount the fluorescent tube(s) on the lamp holders,
d) connect (see § 2),
e) push the gear tray inside the luminaire, and make it slide on the part
;
f) Tighten the middle screw
but turn it no more than 5 or 6 times.
1.3
Install the unit in its straps
after fastening them as described in § 1.1.
1.4
Put carfully the gasket
on the tubular body
.
1.5
Position the mobile flange
so that it properly covers the seal
1.6
Tighten the middle screw
assuring that the mobile flange
properly sits on the seal
.
Fully tighten the
middle screw
to ensure the required tightness of the unit. Avoid excessive tightening (a tightening torque of
1,7 N.m + 0/- 0.1 is to be applied to the middle screw
). To be sure it is well locked, compare the deformation
of your joint (under the screw
) with the following photos:
1.6
Tighten the cable gland (tightening torque of 5 N.m +/- 0.5).
1.7
If necessary, rotate the unit in order to position it in the lighting direction as desired by opening the fixing
straps
