environment before making a permanent installation.
The following are general recommendations that will maximize sensor runs and minimize
problems:
•
Avoid sensor runs adjacent to industrial equipment power cables. These cables can have high
voltage spikes that may induce noise on the sensor signals. Similarly, avoid running sensor
cables near any radio transmission antennas or coaxial feed-lines.
• Protect any exposed electrical connections with appropriate weather protection.
• Do not “hot plug” wall mount Temperature/Humidity sensors into a powered X-600M. Use the
internal jumpers in the Temperature/Humidity module to enable/disable the sensors as needed
during discovery and test.
•
Due to the broad range of applications and environments where the X-600M may be employed,
successful installations of long sensor runs may vary significantly.
Cat 5 and Cat 5e network cable have proven to be an effective and low-cost solution for long runs. Other
cable types can be used, but cable capacitance may limit the length. The illustration below shows the
recommended connections using Cat 5 network cable. Connect all unused conductors to ground.
