Safety Notes
MITX-430/MITX-440-DVI-2E Installation and Use Guide (6806800K37B) 119
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
RJ-45 connectors on some products are either twisted-pair Ethernet (TPE) or E1/T1/J1 networ k
interfaces. Connecting an E1/T1/J1 line to an Ethernet connector may damage your system.
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
100m.
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.
