3. Installation
The MLX can be mounted on a wall or a 2” pipe. The housing is NEMA 4X/IP66/IP67 rated so it
can be mounted outside in the field.
"0 Ring" seals MUST be carefully examined after opening to ensure that the NEMA
4X/IP66/IP67 protection is maintained. Damaged seals MUST be replaced.
The complete electrical circuit in the hazardous area MUST be capable of withstanding an AC
test voltage of 500V RMS to earth or frame of the apparatus.
Where there is a possibility of attack by aggressive substances, the MLX must be protected by a
suitable enclosure, capable of protecting it from the environment and the effects of impact,
thermal or mechanical stress.
Do not install the MLX in the following conditions:
• Extreme Temperatures beyond the temperature rating of the instrument.
• High vibration areas above the vibration rating of the instrument.
• Extremely corrosive environments.
Installation MUST comply with the requirements specified in the appropriate standards and must
be performed by suitably qualified staff only.
