1. Safety information
The non-sparking empty enclosures of the ALUBOX-EX series are classified as Group II, Category
3 GD enclosures that can be used for fixed installations in environments with potential risk of
explosion identified as Zone 2 and Zone 22.
Use the non-sparking enclosures of the ALUBOX-EX series for their approved use only, and keep
them fully intact and thoroughly clean. These enclosures were designed to withstand an impact of
4J, and to be used under normal vibration conditions.
For the wall fastening, use the appropriate fixing slots on the exterior of the product. Carry out the
internal and external earthing connection at the earth symbol. In case of incorrect assembly, the
degree of protection cannot be guarantee. Use only original parts supplied by. No modification/work
can be made to the enclosure unless expressly indicated in this manual.
Always comply with national safety and accident-prevention rules as well
as with the safety instructions contained in this manual when working on
the enclosure.
2. Compliance with standards
The empty enclosures type ALUBOX-EX are designed for:
- Zone 2
- Zone 22
Comply with the following directives:
- EN 60079-0:2012+A11:2013
- EN 60079-15:2010
- EN 60079-31:2014
They are made and tested in accordance with the Directive 2014/34/EU, with the best engineering
practices and pursuant to standard ISO 9001.

3.4 Service temperature
The service temperature should be between -20 °C to +90 °C.
Do not use the enclosure outside this temperature range.
3.5 Limitations of use
The products guarantee impact resistance performance required by the low mechanical risk standard
condition 4J.
Equipment marked as a component: if the enclosure is intended to be used in
a hazardous area, the user is required to subject the entire unit to a
2014/34/EU type analysis, to be carried out by a Notified Body. Instructions
pertaining to installation, use and maintenance must always be included with
the certified electrical device.
4. Installation
The installation must be carried out by qualified personnel pursuant to the
relevant professional code (for example, EN 60079-14), pursuant to national
safety and accident-prevention rules and pursuant to this manual.
4.1 Instructions for safe use
The IP degree of protection of the enclosure must maintained in the area of installation by using
the following arrangement of cable glands, plugs and gaskets as well as in compliance with
installation standards. Should other certified components be assembled in the enclosure, the user
will have to take into consideration any limitations listed on the relevant certificates.
In case holes need to be drilled in the enclosures, use tools suited to the material the
enclosure is made of (Aluminium die-casting) and make sure you are using the proper
drilling and feeding speed. The holes must fall within the drillable area defined for each wall and
must be carried out up to standard, without any burrs.
The thickness of the enclosure (min. 1 mm) DOES NOT allow the holes to be threaded.
These instructions presume that the necessary cable entries have been pre-drilled in the enclosure.
The cable glands are usually assembled during the installation.
The enclosure must be installed intact and free of any damage.
4.2 Accessories
Accessories must be assembled before the enclosure is installed and in accordance with the relevant
instructions.
4.3 Drilling areas
Table 2 - Fig. 2 - page 1
4.4 Protection – Earthing
A threaded hole is provided on an
exterior wall of the enclosure, (Fig.3), for
connection to the earth conductor; use
terminal screws and the non-rotating
bracket supplied with the enclosure as
indicated in the figure.
Carry out the equipotential connection
between the bottom and the cover of the
box using the screws and inserts
supplied as standard equipment.
4.5 Cable glands
Use only cable glands that have been approved Ex e and Ex tc IIIC.
Certified cable glands and plugs can be assembled only if their IP degree of protection is suited to the IP
degree of protection of the enclosure.
Make sure that the cable glands used are suitable for the cable so as to prevent any loosening and
guarantee a permanent seal against humidity.
Other conditions are indicated in the cable gland instructions.
