CAUTION: 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 must be met:
• This equipment must 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.
•
This equipment must 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 must be earthed elsewhere.
• The DC supply source is to be located within the same premises as the equipment.
• Switching or disconnecting devices must not be in the earthed circuit conductor between the
DC source and the point of connection of the earthing electrode conductor.
CAUTION: To reduce the risk of electric shock or energy hazards:
• This equipment must be installed by trained service personnel, as defined by the NEC and IEC
60950-1, Second Edition, the standard for Safety of Information Technology Equipment.
•
Connect the equipment to a reliably grounded SELV source. An SELV source is a secondary
circuit that is designed so normal and single fault conditions do not cause the voltages to
exceed a safe level (60 V DC).
•
The branch circuit overcurrent protection must be rated 24 A.
