The average value is measured by week. The maximum value is the extreme value within a week, which does
not exceed 30 minutes per day.
3. ESD Requirements
ESD measures have been taken during circuit design, but strong static electricity will still damage the printed
circuit card (PCB). Static electricity on the communication network connected to the router is mainly originated
from the following sources:
 Outdoor high-voltage transmission line, lightning, and other exterior electric fields
 Indoor environment, flooring material, complete appliance structure, and other in-house systems
To avoid the damage caused by static electricity, take the following measures:
 Properly ground the router and floor.
 Apply indoor dust control.
 Maintain proper temperature and humidity.
 Before touching the circuit board, wear an ESD wrist strap and an ESD uniform.
 Place the PCB disassembled face up on the antistatic workbench or in the electromagnetic shielded bag.
 When observing or transferring the circuit board of Router, touch the outer edge of the PCB and avoid direct
contact with the components on the PCB.
4. Anti-Interference Requirements
 Take effective power grid interference control measures against the power supply system.
 Keep the working ground of the Router far away from the grounding device or lightning grounding device of
the power device instead of sharing.
 Keep the router far away from the high-power radio-transmitting station, radar-transmitting station, and other
high-frequency and heavy-current devices.
 Take electromagnetic shielding measures when necessary.
5. Checking the Installation Location
Regardless of whether the Router is installed in the cabinet or on the workbench, comply with the following
requirements:
