ATEX/IECEx Special Conditions for Safe Use
The following conditions relate to safe installation and/or use of the equipment.
•
The permitted ambient temperature range for the PD6606/PD6608 is -40°C to 70°C.
•
The equipment must be installed in an enclosure which provides a minimum degree of protection of
IP20 for the equipment connections.
•
Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this equip-
ment may generate an ignition-capable level of electrostatic charge. Therefore, the equipment shall not
be installed in a location where the external conditions are conducive to the build-up of electrostatic
charge on such surfaces. This is particularly important if the equipment is installed in a zone 0 location.
In addition, the equipment shall only be cleaned with a damp cloth.
•
The equipment loop/power port must be connected to an intrinsically safe barrier with U
o
≥ 11V.
•
Entity parameters must meet the following requirements:
U
i
: 30 V; I
i
: 175 mA; C
i
: 0 μF; L
i
: 0 μH; P
i
: 1.0 W
•
For ATEX Certification, barrier and transmitter must be ATEX Certified with Entity Parameters and must
be connected per manufacturer’s instructions.
For European Community:
The PD6606/PD6608 must be installed in accordance with the Essential Health & Safety Requirements of
Directive 2014/34/EU, the product certificates CML 17ATEX2015X and IECEx CML 17.0008X, and the
product manual.
UL/C-UL Special Conditions for Safe Use
•
Associated apparatus may be in a Division 2 or Zone location if so approved.
•
Under certain extreme circumstances, the non-metallic parts incorporated in the enclosure of this equip-
ment may generate an ignition-capable level of electrostatic charge. Therefore the equipment shall not
be installed in a location where the external conditions are conducive to the build-up of electrostatic
charge on such surfaces. This is particularly important if the equipment is installed in a zone 0 location.
In addition, the equipment shall only be cleaned with a damp cloth.
•
The equipment shall be installed in a tool secured enclosure which provides a minimum degree of pro-
tection of IP20 for the equipment connections.
•
Entity parameters must meet the following requirements:
U
i
: 30 V; I
i
: 175 mA; C
i
: 0 μF; L
i
: 0 μH; P
i
: 1.0 W

For Division 2 and Zone 2 Applications:
Division 2 and Zone 2 installations do NOT require the use
of an intrinsically-safe barrier or intrinsically-safe entity parameters. Class I, Division 2, Groups A, B, C,
and D T4 and Class I, Zone 2, Group IIC T4, -40C <= Ta <= +70C.
Ratings: V = 30 V dc, I = 30 mA; Relay Ratings: 250V ac/dc 1A
For North American Community:
Installation and service of this device and/or associated apparatus (barrier) should be performed only by
trained service personnel and must be installed in accordance with the manufacturer’s control drawing,
Article 504 of the National Electric Code (ANSI/NFPA 70) for installation in the United States, or Section
18 of the Canadian Electrical Code for installations in Canada.
