Humidity. Operating humidity should be kept between 10 and 95% relative humidity (noncondensing).
Electrostatic Discharge (ESD)
Your system must be protected from static electricity. Take the following measures to ensure optimum
system performance:
• Keep relative humidity at 50 to 70%.
• Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
closet. Check the appropriateness of floor mats and flooring.
• Connect conductors (metals, etc.) to ground, using dedicated grounding lines.
• Use electrostatically safe equipment and the ESD straps that are provided with your equipment. All
Alpine and BlackDiamond switches come with ESD wrist strap connectors and wrist straps as
shown in Figure 10.
