dangers.
2.2 Installation Environment Requirements
The RG-AP820(AR) must be used indoors. Install theAP indoors to ensure its normal operation and prolong the
service life. The installation site must meet the following requirements.
2.2.1 Installation Requirements
Install the AP in an open environment. If the AP is installed in a closed environment, ensure that the
environment has proper ventilation and heat dissipation.
Ensure that the installation location is sturdy enough to support the weight of theAP and its accessories.
Ensure that the dimensions of the installation location for the AP are proper with sufficient clearance around
the AP for heat dissipation. The installation location must be at least 2 m away from base station antennas
to prevent mutual interference.
2.2.2 Ventilation Requirements
Reserve sufficient clearance around the AP for heat dissipation when installing the AP, because the AP adopts
a fan-free design.
2.2.3 Temperature and Humidity Requirements
To ensure the normal operation and prolonged service life of the AP, maintain an appropriate temperature and
humidity in the equipment room. An equipment room with too high or too low temperature and humidity for a
long period may damage the device.
In an environment with high humidity, the insulating material may have poor insulation or even leak electricity.
Sometimes it is also prone to changes in the mechanical properties and causes rusting of metal parts.
In an environment with low relative humidity, the insulating strip may dry and shrink, static electricity may
occur and damage the internal circuits of the AP.
Too high temperatures can accelerate the aging of insulation materials, greatly reducing the reliability of the
AP and severely affecting its service life.
The following table describes the temperature and humidity requirements for the RG-AP820(AR).
