2 Preparing for Installation
2.1 Safety Precautions
To avoid personal injury and device damage, carefully read the safety precautions before you install the RG-S2915-L series
switches.
The following safety precautions may not cover all possible dangers.
2.1.1 Installation Safety
 Keep the chassis clean and free from any dust.
 Do not place the device in walking areas.
 During the installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be hooked by the
chassis.
 Cut off all the power supplies and unplug all power cords before handling the switch.
2.1.2 Handling Safety
 Prevent the device from being frequently handled.
 Keep balance and prevent personal injuries when handling the switch.
 Cut off all the power supplies and unplug all power cords before moving or handling the device.
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.
 Find out the position of the indoor emergency power switch before installation. Cut off the power switch in case of accidents.
 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 switch in a damp location, and keep the switch away from liquid.
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 sixteen identical power supplies, the
leakage current of each power supply is equal to or less than 3.5 mA, and the leakage current of the system totals 56 mA. A
leakage protector with 30 mA rated action current supports less than five power supplies (that is, Action current of the leakage
