1. Introduction
1.1. This “Appendix Exd.IECEx” applies to transmitters of types APC-2000ALW/XX, APR-2000ALW/XX,
APR-2200ALW/XX, APR-2000GALW/XX and APR-2000YALW/XX in Exd versions only, marked on
the rating plate as shown in p.3 and denoted Exd in the Product Certificate.
1.2. The appendix contains supplementary information relating to the Exd (flame-proof) versions compatible
with IECEx certificate of mentioned transmitters.
During installation and use of Exd transmitters, reference should be made to DTR.APC.APR.ALW.03(ENG)
in conjunction with “Appendix Exd.IECEx”.
2. Use of APC…, APR… transmitters in dangers zones
2.1. The transmitters are produced in accordance with the requirements of the following standards:
IEC 60079-0:2011 ed.6, IEC 60079-1:2014 ed.7, IEC 60079-11:2011 ed.6, IEC 60079-31:2013 ed.2,
IEC 60079-26:2006 ed.2.
2.2. The transmitters may operate in areas where there is a risk of explosion, in accordance with the rating
of the explosion protection design:
Depending on type and device version the following markings are used:
2.2.1. Equipment protection level EPL Ga/Gb and Da/Db: (Not applicable to APR-2000GALW / XX)
Ex db ia I Mb (version with enclosure 1.4401 (316))
Ex ia/db IIC T6/T5 Ga/Gb
Ex ia/t IIIC T85ºC/T100ºC Da/Db
IECEx KDB 14.0001X
marking T6 and T85°C applies to range -40ºC <Ta ≤ 45ºC
marking T5 and T100°C applies to range -40ºC <Ta ≤ 75ºC
2.2.2. Equipment protection level EPL Gb, Db and Mb:
Ex db ia I Mb (version with enclosure 1.4401 (316))
Ex ia /db IIC T6/T5 Gb
Ex ia /t IIIC T85ºC/T100ºC
Db
IECEx KDB 14.0001X
marking T6 and T85°C applies to range -40ºC <Ta ≤ 45ºC
marking T5 and T100°C applies to range -40ºC <Ta ≤ 75ºC
2.3. Equipment protection level (EPL) and hazard areas.
Equipment protection level (EPL) Ga/Gb (Da/Db) means that the transmitter may be installed within a type 1
(21) or 2 (22) danger zone and process connections can connect to zone 0 (20) (example shown below – fig.
1a). Equipment protection level EPL Gb (Db) means that the transmitter together with process connections
may be installed within a type 1 (21) or 2 (22) danger zone (example shown below – fig. 1b).
Transmitter marked Mb turn off if there is risk of an explosive atmosphere.
