2 Preparation Before Installation
2.1 Safety Suggestions
To avoid personal injury and device damage, carefully read the safety suggestions before you install the RG-ES100
series switch.
The following safety suggestions do not cover all possible dangers.
2.1.1 Installation
Keep the chassis clean and free from any dust.
Do not place the equipment in a walking area.
Do not wear loose clothes or accessories that may be hooked or caught by the device during installation and
maintenance.
Turn off all power supplies and remove power sockets and cables before installing or uninstalling the device.
2.1.2 Movement
Do not frequently move the device.
When moving the device, note the balance and avoid hurting legs and feet or straining the back.
Before moving the device, turn off all power supplies and dismantle all power modules.
2.1.3 Electricity
Observe local regulations and specifications when performing electric operations. Relevant operators must be
qualified.
Before installing the device, carefully check any potential danger in the surroundings, such as ungrounded power
supply, and damp or wet ground or floor.
Before installing the device, find out the location of the emergency power supply switch in the room. First cut off the
power supply in the case of an accident.
Try to avoid maintaining the switch that is powered on alone.
Be sure to make a careful check before you shut down the power supply.
Do not place the device in a damp location. Do not let any liquid enter the chassis.
Any nonstandard and inaccurate electric operation may cause an accident such as fire or electrical shock, thus
causing severe even fatal damages to human bodies and the device.
Direct or indirect touch through a wet object on high-voltage and mains supply may bring a fatal danger.
If a power supply system is equipped with a leakage protector (leakage current switch or breaker), the rated leakage
action current of each leakage protector is twice greater than the maximum leakage current of all the power supplies
in the system. For example, if a system is equipped with twenty identical power supplies, the leakage current of
