Preparation before Installation
supplies (that is, Action current of the leakage protector/2/Maximum leakage current of each power supply = 30/2/3.5
= 4.28). In other words, the leakage protector with 30 mA rated action current supports no more than four power
supplies. In this case, the sixteen power supplies in the system require at least four leakage protectors with 30 mA
rated action current and each leakage protector supports four power supplies. If power supplies in a system differ in
models, the rated leakage action current of each leakage protector divided by two is greater than the sum of maximum
leakage currents of all the power supplies. The rated leakage non-action current of a leakage protector shall be 50%
of the leakage action current. Take a leakage protector with 30 mA rated leakage action current as an example. The
rated leakage non-action current shall be 15 mA. When the leakage current is below 15 mA, the protector shall not
act. Otherwise, misoperation may easily occur due to high sensitivity and thus the leakage protector trips, devices
are powered off, and services are interrupted.
To guarantee personal safety, the rated leakage action current of each leakage protector in the system must be equal
to or less than 30 mA (human body safety current is 30 mA). When twice of the total leakage current of the system is
greater than 30 mA, the system must be equipped with two or more leakage protectors.
For the leakage current value of each power supply model, see the power supply model parameter table in Chapter
1.
2.1.4 Static Discharge Damage Prevention
To prevent damage from static electricity, pay attention to the following:
Proper grounding of grounding screws on the back panel of the device.
Indoor dust prevention
Proper humidity conditions
2.2 Installation Site Requirements
To ensure the normal working and a prolonged durable life of the equipment, the installation site must meet the following
requirements.
2.2.1 Installation Site
If the router is installed in the cabinet, the following requirements shall be met:
Make sure sufficient room has been reserved for the air intake and air vent of router to facilitate the heat elimination
of the router chassis.
Make sure the cabinet is equipped with a good ventilation and cooling system.
Make sure the cabinet and workbench is steady enough and capable of withstanding the weight of the router and its
accessories.
Make sure the cabinet is properly grounded.
2.2.2 Ventilation
For the RG-EG210G-E router, a sufficient space (at least 10 cm distances from both sides and the back plane of the
cabinet) should be reserved at the ventilation openings to ensure the normal ventilation. After various cables have been
connected, they should be arranged into bundles or placed on the cabling rack to avoid blocking the air inlets. It is
