Introduction
Safety Marking
3
This apparatus is an intrinsically safe device suitable that is intended to be installed in hazardous areas
characterized by the presence of gases, vapours or mists formed by groups IIA or IIB dangerous substances. The
Mag-FLEX is in compliance with the Directive 94/9/EC (ATEX). The sample of the type has been tested by TÜV
NORD CERT GmbH, ID 0044, Langemarckstraße 20, 45141 Essen, Germany, and approved by the issue of the
EC type certificate, where the complete name Mag Plus 1 Flex is used.
TÜV 12 ATEX 105828
The manufacturing process has been approved by BASEEFA which has authorized the use of its ID 1180 after the
symbol of the CE marking.
When used in potentially explosive atmospheres, the maximum service temperature depending on the temperature
class and category is shown below:
EC-TYPE CERTIFICATES FOR AN INTRINSICALLY SAFE SYSTEM
TLS Monitoring Systems are installed according to the conditions specified in the applicable ATEX Certificates.
ATEX Certificate Number DEMKO 06 ATEX 137480X is the system certificate that details all of the equipment
that is approved for use in a TLS Monitoring System. Except for the cables used to connect intrinsically safe
apparatus, information contained on the system certificate and each of the device certificates, provide the safety
related information (i.e., Ex ia) required to install a TLS Monitoring System. Cables used to connect intrinsically
safe apparatus must be considered in determining ATEX compliance and are limited to the maximum allowable
cable parameters listed in this manual. For assistance in calculating the required (Ex ia) safety parameters, contact
GVR as described on the inside cover of this manual. Additional equipment compliance information is available on
the EC Declaration of Conformity including the technical standards applied by the Notified Body in creating the
respective ATEX Certificates.
