ATEX and IECEx Safety Instructions for 9376-SP Trunk Surge 
Module

The following information is in accordance with the 
Essential Health and Safety Requirements (Annex II) of the 

 

EU Directive 2014/34/EU [the ATEX Directive - safety of apparatus] 
and is provided for those locations where such requirements are 
applicable.

General

a)

This module must only be installed, operated and 
maintained by competent personnel. Such personnel shall 
have undergone training, which included instruction on the 
various types of protection and installation practices, the 
relevant rules and regulations, and on the general principles 
of area classification. Appropriate refresher training shall be 
given on a regular basis. [See clause 4.2 of EN 60079-17].

b) 

This module has been designed to provide protection 
against all the relevant additional hazards referred to in 
Annex II of the directive, such as those in clause 1.2.7.

c) 

This module has been designed to meet the requirements of
EN 60079-0, EN 60079-1, EN 60079-7, EN 60079-18.

Installation

d)

The installation must comply with the appropriate European, 
national and local regulations, which may include reference 
to the IEC code of practice IEC 60079-14. In addition, 
particular industries or end users may have specific 
requirements relating to the safety of their installations and 
these requirements should also be met. For the majority of 
installations the Directive 1999/92/EC [the ATEX Directive - 
safety of installations] is also applicable.

e)

This module can be mounted in a Safe area or a Zone 2 or 
Zone 1 hazardous area. When mounted in a Zone 2 or Zone 
1 location the module must be provided with an enclosure, 
which offers an additional degree of protection appropriate 
to the area classification.

f)

Unless already protected by design, this module must be 
protected by a suitable enclosure against: 
i) mechanical and thermal stresses 
in excess of those noted in the certification documentation 
and the product specification. 
ii) aggressive substances, excessive dust, moisture and other 

contaminants.

Read also the Schedule of Limitations (below) for any additional or 
more specific information.

Schedule of Limitations

1)

The 9376-SP Trunk Surge Protector must be housed in an 
appropriately certified Ex e enclosure.

2) 

The 9376-SP Trunk Surge Protector must plug into 
equipment that uses the socket part of the connector 
covered by certificate TUV09ATEX555354U.

3) 

Due to the presence of transient protection components 
between the fieldbus and earth connections, the 
9376-SP Trunk Surge Protector will not withstand a 500V 
a.c. dielectric strength test. This must be taken into account 
during installation.

4) 

The ambient temperature must not exeed +75°C.

5) 

The 9376-SP Trunk Surge Protector shall only be powered 
from supplies conforming to IEC 61158.

6) 

The 9376-SP Trunk Surge Protector shall only be connected 
into equipment that causes the secondary latching 
connector to limit movement before the live-demateable 
connector plug and socket metal parts separate by over 
1.9mm.

Inspection and maintenance

Inspection and maintenance should be carried out in accordance 
with European, national and local regulations which may refer to 
the IEC standard IEC 60079-17. In addition specific industries or 
end users may have specific requirements which should also be 
met.

Repair

 

This module cannot be repaired by the user and must be
replaced with an equivalent certified product.

Marking

Each module is marked in compliance with the above
Directive and CE marked with the Notified Body
Identification Number.

This information applies to modules manufactured during or after 
the year 2010.
