■■ Site Requirements
Temperature/Humidity
Please keep a proper temperature and humidity in the equipment room. Too high/low humidity may lead to bad insulation, electricity leakage, mechanical property changes and corrosions. Too high temperature may accelerate aging of the insulation materials and can thus significantly shorten the service life of the device. For normal temperature and humidity of the device, please check the following table.
Environment |
Temperature |
Humidity |
|
|
|
Operating |
0 ~ 40 |
10% ~ 90%RH Non-condensing |
|
|
|
Storage |
-40 ~ 70 |
5% ~ 90%RH Non-condensing |
|
|

Clearness
The dust accumulated on the Router can be absorbed by static electricity and result in poor contact of metal contact points. Some measures have been taken for the device to prevent static electricity, but too strong static electricity can cause deadly damage to the electronic elements on the internal circuit board. To avoid the effect of static electricity on the operation of the Router, please attach much importance to the following items:
■■
■■
Dust the device regularly, and keep the indoor air clean.
Keep the device well grounded and ensure static electricity has been transferred.
Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be affected by external interferences, such as conducted emission by capacitance coupling, inductance coupling, and impedance coupling. To decrease the interferences, please make sure to take the following measures:
■■
■■
■■
Use the power supply that can effectively filter interference from the power grid.
Keep the device far from high-frequency, strong-current devices, such as radio transmitting station.
Use electromagnetic shielding when necessary.

Installation
Gigabit Dual-WAN VPN Router
Lightening Protection
Extremely high voltage currents can be produced instantly when lightning occurs and the air in the electric discharge path can be instantly heated up to 20,000 . As this instant current is strong enough to damage electronic devices, more effective lightning protection measures should be taken.
■■
■■
■■
■■
Ensure the rack and device are well earthed.
Make sure the power socket has a good contact with the ground. Keep a reasonable cabling system and avoid induced lightning. Use the signal SPD (Surge Protective Device\ when wiring outdoor.
Note: For detailed lightning protection measures, please refer to Chapter 3 Lightning Protection.
Installation Site
S
When installing the device on a rack or a flat workbench, please note the following items:
■■
■■
■■
The rack or workbench is flat and stable, and sturdy enough to support the weight of 5.5kg at least.
The rack or workbench has a good ventilation system. The equipment room is well ventilated.
The rack is well grounded. Keep the power socket less than 1.5 meters away from the device.
