2 Preparation before Installation
2.1 Safety Suggestions
To avoid personal injury and equipment damage, please 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 the 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/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 equipment 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 equipment.
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 (also referred to as "leakage current switch" or
"leakage current breaker"), the rated leakage action current of each leakage protector is greater than twice of the
theoretical 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 each power supply is equal to or less than 1.5mA, and
