5.6.11 Use of the reader in hazardous areas for gases
Temperature class delineation for gases
The temperature class of the reader for hazardous areas depends on the ambient
temperature range:
Ambient temperature range
-25 °C to +70 °C
Ignitions of gas-air mixtures
When using the RF380R reader, check to ensure that the temperature class is observed in
respect of the requirements of the area of application
Non-compliance with the permitted temperature ranges while using the reader can lead to
ignitions of gas-air mixtures.
5.6.12 Installation and operating conditions for the hazardous area
a) The connector on the RF380R must be grounded via its supply line.
b) Use of the equipment in the vicinity of processes generating high charges is not allowed.
c) The plug of the RF380R must not be disconnected in a hazardous atmosphere or under
load.
d) The supply line for the RF380R is not part of this certificate. The supply line must exhibit a
sufficient temperature resistance.
e) The equipment must be mechanically protected when installed.
