supplies (that is, Action current of the leakage protector/2/Maximum leakage current of each power supply = 30/2/3
= 5). In other words, the leakage protector with 30 mA rated action current supports no more than four power supplies.
In this case, the eight power supplies in the system require at least two leakage protectors with 30 mA rated action
current and each leakage protector supports four power supplies. If power supplies in a s ystem 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 les s 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 Electrostatic Discharge Safety
To ensure electrostatic discharge s afety, there are some precautions:
Properly ground the device and floor.
Keep the indoor installation environment clean and dust-free.
Maintain appropriate humidity conditions.
2.1.5 Laser Safety
Among the modules supported by the RG-S5760C-X series, here are many transceiver modules that are Class I laser
products.
Precaution:
When a fiber transceiver works, ensure that the port has been connecte d with a fiber or covered by a dust cap to
keep out dust and prevent it from burning your eyes .
Do not approach or stare at any fiber port under any circumstances, as this may cause permanent damage to your
eyes.
2.2 Installation Environment Requirements
Install the switch indoors to ensure its normal operation and prolonged service life.
The installation site must meet the following requirements.
2.2.1 Ventilation Requirements
RG-S5760C-X should be placed at least 10 cm away from surrounding walls to ensure normal heat dissipation. After
various cables are connected, bundle the cables or place them in the cable management bracket to avoid blocking air
inlets.
