1.4 EMC Protection
1.5 System Security
This section describes all points crucial to the VoIPBox’s sys-
tem security.
The VoIPBox’s location must support normal operation ac-
cording to EN ETS 300 386. Be sure to select the location with
the following conditions in mind:
Use shielded cables.
Do not remove any housing components. They provide EMC
protection.
Location: Make sure you install the system in a clean, dry,
dust-free location. If possible, use an air-conditioned site.
The site must be free of strong electrical or magnetic
fields, which cause disrupted signals and, in extreme cas-
es, system failure.
Temperature:
The site must maintain a temperature between 0 and
35°C. Be sure to guard against temperature fluctuations.
Resulting condensation can cause short circuiting. The hu-
midity level may not exceed 80%.
To avoid overheating the system, make sure the site pro-
vides adequate ventilation.
