SPECIFIC CONDITIONS OF USE: YES as shown below:
The NAMUR Pulse Isolator 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 IEC 60664-1.
If the NAMUR Pulse Isolator is installed in an explosive atmosphere where equipment protection level Gc is required 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 fulfil the same requirements.
