conditions
of
use
The HART-Transparent Repeater shall be installed in a controlled environment with suitable
reduced pollution, limited to pollution degree 2 or better.
The non-intrinsically safe circuits may only be connected to an overvoltage category I or II power
source, as defined in EN 60664-1.
If the HART-Transparent Repeater is installed in an explosive atmosphere where the use of
apparatus of equipment category 3 G is required, the following special condition for safe use
applies:
The HART-Transparent Repeater shall be installed in an enclosure in type of protection Ex n or
Ex e, providing a degree of protection of at least IP54.
Cable entry devices and blanking elements shall fulfill the same requirements.
