3.7 Grounding
A PGND is installed on the back of RG-S6220. First connect the PGND to the grounding terminal of the cabinet and
then connect the grounding terminal to the grounding bar of the equipment room.
Precautions
The cross sectional area of the grounding cable should be determined according to the possible maximum current.
Cables of good conductor should be used.
Do not use bare wire.
The grounding resistance for combined grounding should be less than 1Ω.
To guarantee the security of the person and the device, the RG-S6220 must be well-grounded. The grounding
resistance should
be less than 1Ω.
A service person should check whether or not the socket-outlet from which the device is to be powered provides a
reliable connection to the building protective earth. If not, the service person should arrange for the installation of a
protective earthing conductor from the separate protective earthing terminal to the protective earth wire in the
building.
The socket-outlet should be installed at a location near the device easy for operation.
