Chapter 2 Installation Preparations
2.1 General Site Requirements
The SecPath V100-S must be used indoors. To guarantee normal operation and
longevity of your device, its installation site should meet the requirements described in
this chapter.
2.1.1 Temperature and Humidity
The equipment room must maintain proper humidity to prevent poor insulation,
electricity creepage and corrosion accompanying high humidity, or washer contraction
and electrostatic discharge accompanying low humidity. In dry environments where the
relative humidity is very low, electrostatic discharge (ESD) is more likely to happen
causing the complementary metal-oxide-semiconductor (CMOS) circuitry to fail.
The following table lists the temperature and humidity requirements.

2.1.2 Cleanness
Dust is hazardous to the operating safety of your device. Dust buildup on the chassis
may result in static absorption, causing poor contact of metal components or points.
When indoor humidity is extremely low, this is more likely to happen to shorten the
useful life of the device and cause communication failures.
The equipment room must be free of explosion hazards and the electrical and magnetic
conductible dust as well. The following table lists the limits on dust particles:
