Installaon 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 1113106.
When the apparatus is being used in accordance with the type of protecon: Ex nA IIC T4
(–40°C ≤ Ta ≤ +85°C), the apparatus must be mounted in an enclosure capable of withstand-
ing a 7 joule impact (at -40°C if non-metallic) and provide a degree of ingress protecon of at
least IP54.
Driver is cered as a component only and must be installed in a suitable enclosure accept-
able to local authories.
Field wiring from the safe area to the transmier must conform with the local electrical code.
The transmier provides a non-incendive circuit to probe and extension cable, which there-
fore require no further electrical protecon.
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.
