2 Preparing for Installation
2.1 Safety Precautions
To avoid personal injury and equipment damage, please carefully read the safety precautions before you install the
RG-S5760C-X series.
The following safety precautions may not cover all possible dangers.
2.1.1 General Safety Precautions

Keep the chassis clean and dust-free.

Do not place the device in walking areas.

Do not wear loose clothes , ornaments, or any other things that may be hooked by the chassis during the installation
and maintenance.

Cut off all power supplies and unplug all power cords before dismantling the cabinet.
2.1.2 Handling Safety

Prevent the switch from being frequently handled.

Cut off all power supplies and unplug all power cords before moving or handling the switch.

Keep balance and prevent personal injuries when handling the switch.
2.1.3 Electric Safety

Observe local regulations and specifications during electric operations. Only personnel with relevant qualifications
can perform such operations.

Check whether there are potential risks in the work area. For example, check whether the power supply is grounded,
whether the grounding is reliable, and whether the ground is wet.

Learn about the position of the indoor emergency power switch before installation. Cut off the power switch in cas e
of accidents.

Do not maintain the switch that is powered-on alone.

Check the switch carefully before shutting down the power supply.

Do not place the switch in a wet position, and keep the chassis away from liquid.
Improper or incorrect electric operations may cause a fire, electric shock, and other accidents, and lead to severe
and fatal personal injury and device damage.
Direct or indirect touch on high voltage or mains power supply through wet objects may cause fatal dangers.
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 mA, and the leakage
current of the system totals 24 mA. A leakage protector with 30 mA rated action current supports less than five power
