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 current 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 product model, see the technical specifications table of the corresponding product model
in Chapter 1.
2.1.4 Electrostatic Discharge Safety
To prevent damage from electrostatic discharge, pay attention to the following points:
Ensure that the grounding screw on the back panel of the device is grounded. Ensure that the AC power socket is a single-phase
three-core power socket with protective earthing conductors (PE).
Keep the indoor installation environment clean and free of dust.
Keep the indoor humidity within a certain range.
2.1.5 Laser Safety
The RG-S2915-L series switches support various types of optical modules available in the market and these optical modules are Class
I laser products. Improper use of optical modules may cause damage. Therefore, pay attention to the following points when you use
them:
When a fiber transceiver works, ensure that the port has been connected with a fiber-optic cable or covered by a dust cap to
keep out dust and prevent it from burning your eyes.
When the optical module is working, do not pull out the fiber-optic cable and stare at the transceiver interface or you may hurt
your eyes.
Do not approach or stare at any optical port under any circumstances, as this may cause permanent damage to your eyes.
2.1.6 Storage Security
To ensure the normal operation of the device, maintain a proper storage environment in accordance with the storage
temperature/storage humidity requirements in the technical specifications table of the corresponding device.
If the storage time exceeds 18 months, you must power on the device and keep it running for 24 hours without interruption for
device activation.
