Grounding
A good grounding system is the basis for the stable and reliable operation of the RG-2910C-XS-P 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.
The correct connection of grounding lines guarantees the lighting and interference resistance of switches and
must be performed with precision.
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, downlead
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.
