Hardware Installation and Reference Guide

 

Preparation before Installation

 

Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements, as such 

poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The equipment room 

should be protected from the intrusion of harmful gases such as sulfur dioxide, sulfured hydrogen, nitrogen dioxide, and 

chlorine), whose requirements are listed in Table 2-3.

Both average and maximum value are measured for a week. The switch cannot be placed in the environment with 

the maximum density for over 30 minutes every day.

Grounding

 

A good grounding system is the basis for the stable and reliable operation of the RG-S1920 series switch. It is the chief 

condition to prevent lightning stroke and resist interference. Please carefully check the grounding conditions on the 

installation site according to the grounding requirements, and perform grounding operations properly as required.

 

 

Effective grounding of the switch is an important guarantee for lightning protection and interference resistance. 

Therefore, connect the grounding line of the switch properly.

 

Safety Grounding

 

The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable. Otherwise, 

when the insulating resistance decreases the power supply and the enclosure in the equipment, electric shock may occur.

 

 

The building must provide protective grounding connection to ensure that the device is connected to the protection 

location.

 

 

The installation and maintenance personnel must check whether the A.C. socket is well connected to the protection 

location of the building, if not, they should use a protective grounding wire to connect the grounding end of the A.C. 

socket to the building's protection location.

 

 

The power supply socket must be installed in a place that is near to the device and where users can operate the 

device easily.

 

 

Before the installation of the device, make sure that ground connection is connected at first and disconnected finally.

 

 

The sectional area of the protective grounding wire should be at least 0.75 mm

2

 (18 AWG).

 

 

Use the 3-core power supply line. The sectional area of each pin should be at least 0.75 mm

2

 or 18 AWG.

 

Lightning Grounding

 

The lightning protection system of a facility is an independent system that consists of the lightning rod, download 

conductor and the connector to the grounding system, which usually shares the power reference ground and yellow/green 

safety cable ground. The lightning discharge ground is for the facility only, irrelevant to the equipment.
