ATTENTION 

The AWK-4252A is NOT a portable mobile device and should be 
located at least 20 cm away from the human body. 

The AWK-4252A is NOT designed for the general public. To 
ensure that your AWK-4252A wireless network is safe and 
configured correctly, consult a well-trained technician to assist 
with the installation process. 

ATTENTION 

Use the appropriate antennas for your wireless setup: Use 2.4 
GHz antennas when the AWK-4252A is configured for IEEE 
802.11b/g/n. Use 5 GHz antennas when the AWK-4252A is 
configured for IEEE 802.11a/n/ac. Make sure that the antennas 
are located in an area with a lightning and surge protection 
system installed. 

ATTENTION 

Do not locate the antenna near overhead power lines or other 
electric light or power circuits, or where it can come into 
contact with such circuits. When installing the antenna, take 
extreme care not to come into contact with such circuits, 
because they may cause serious injury or death. For proper 
installation and grounding of the antenna, refer to national and 
local codes (for example, U.S.: NFPA 70; National Electrical 
Code (NEC) Article 810; Canada: Canadian Electrical Code, 
Section 54). 

NOTE 

To meet the standard for IP68 protection, all unused ports 

should be covered with the protective caps.
