Safety Notes
This equipment is designed to permit the connection of the earthed conductor of the DC supply circuit to the earthing conductor at the equipment. If this connection is made, all of the following conditions must be met:
zThis equipment shall be connected directly to the DC supply system earthing electrode conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode conductor is connected.
zThis equipment shall be located in the same immediate area (such as, adjacent cabinets) as any other equipment that has a connection between the earthed conductor of the same DC supply circuit and the earthing conductor, and also the point of earthing of the DC system. The DC system shall not be earthed elsewhere.
zThe DC supply source shall be located within the same premises as this equipment.
zSwitching or disconnecting devices shall not be in the earthed circuit conductor between the DC source and the point of connection of the earthing electrode conductor.
Connectors and Cabling
System Damage
zMake sure that TPE connectors near your working area are clearly marked as network connectors.
zVerify that the length of an electric cable connected to a TPE bushing does not exceed 100 m.
zMake sure the TPE bushing of the system is connected only to safety extra low voltage circuits (SELV circuits).
zIf in doubt, ask your system administrator.
