Specifications 100

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.
