WARNING:

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 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:

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

WARNING:

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 documentation that ships with the power supply.

CAUTION:

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 12 gauge wires.

IMPORTANT:

IMPORTANT: The minimum nominal thread diameter of a pillar or stud type terminal must be 3.5 mm (0.138 in); the

IMPORTANT:

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).

For more information, see the documentation that ships with the power supply.
