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-NBS5200 series.
The following safety suggestions may not cover all possible dangers.
2.1.1 Installation

Keep the chassis clean and free from dust.

Do not place the equipment in a passage.

Do not wear loose clothes or any other things that may be caught by the chassis 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.

While moving the device, keep its balance and avoid your legs, feet and back from being hurt.

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 non-standard and impropriate electric operations may cause an accident such as a fire or electrical shock,
thus causing severe even fatal damage to human bodies and equipment.
Direct or indirect touch through a wet object on high-voltage and commercial electricity 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 eight identical power supplies, the leakage current of each power supply is equal to or less than 3.5 mA, and
