Installaon in Zone 2 and Div. 2 Areas
Zone 2 Area
Baseefa 06ATEX0113X Ex nA IIC T4 (–40°C ≤ Ta ≤ +85°C)
SPECIAL CONDITIONS OF SAFE USE:
Connect the eld wiring in accordance with Metrix drawing 100515.
When the DPS is being used in accordance with the type of protecon: Ex nA IIC T4 (–40°C ≤
Ta ≤ +85°C), the apparatus must be mounted in an enclosure capable of withstanding a 7 joule
impact (at -40°C if non-metallic) and provide a degree of ingress protecon of at least IP54.
The DPS is cered as a component only and must be installed in a suitable enclosure ac-
ceptable to local authories.
Field wiring from the safe area to the transmier must conform with the local electrical
code. The transmier provides a non-incendive circuit to probe and extension cable, which
therefore require no further electrical protecon.
Do not use Dynamic Signal BNC connector or terminal unless area is known to be non-haz-
ardous.
Transmier is cered as a component only and must be installed in a suitable enclosure ac-
ceptable to local authories.
The driver is not capable of withstanding the insulator test required by Clause 6.4.12 of
EN50020:2002. This must be taken into account when installing the driver.

(-40°C < Tamb < 85°C) Temp Code T4 (–40°C ≤ Ta ≤ +85°C)
Connect the eld wiring in accordance with Metrix drawing 100509 for ATEX installaons and
100506 for UL/CSA installaons. The driver requires a minimum of 17 VDC for proper opera-
on. The voltage drop across the specied zener barriers on the installaon drawings with a
10 mA supply current is 4.1 VDC. The minimum loop power supply voltage required is 25.1
VDC plus 1 volt for each 50 Ω of loop resistance. The maximum loop power supply voltage
that may be applied to the safety barrier is 26 VDC. Therefore, the maximum loop resistance
with a 26 VDC supply is 45 Ω.
