HP dl360 g9 8sff cto server [31/152] Rack warnings

Setup 31

IEC 60950-1, Second Edition, the standard for Safety of Information Technology

Equipment.

• Connect the equipment to a reliably grounded Secondary circuit source. A Secondary

circuit has no direct connection to a Primary circuit and derives its power from a

transformer, converter, or equivalent isolation device.

• The branch circuit overcurrent protection must be rated 27 A.

WARNING: When installing a DC power supply, the ground wire must be connected before

the positive or negative leads.

WARNING: Remove power from the power supply before performing any installation steps or

maintenance on the power supply.

CAUTION: The server equipment connects the earthed conductor of the DC supply circuit to the

earthing conductor at the equipment. For more information, see the HP 800W Common Slot -

40Vdc to -72Vdc or 380Vdc DC Input Hot-Plug Power Supply Kit Installation Instructions.

CAUTION: If the DC connection exists between the earthed conductor of the DC supply circuit

and the earthing conductor at the server equipment, the following conditions 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 should 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 should be earthed elsewhere.

• The DC supply source is to be located within the same premises as the equipment.

• Switching or disconnecting devices should not be in the earthed circuit conductor between

the DC source and the point of connection of the earthing electrode conductor.

To connect a DC power cable to a DC power source:

1. Cut the DC power cord ends no shorter than 150 cm (59.06 in).

2. If the power source requires ring tongues, use a crimping tool to install the ring tongues on the

power cord wires.

IMPORTANT: The ring terminals must be UL approved and accommodate 10 gauge wires.

IMPORTANT: The minimum nominal thread diameter of a pillar or stud type terminal must be

3.5 mm (0.138 in); the diameter of a screw type terminal must be 4.0 mm (0.157 in).

3. Stack each same-colored pair of wires and then attach them to the same power source. The power

cord consists of three wires (black, red, and green).

Power Supply Installation Instructions.
