Statement 34:
CAUTION:
To reduce the risk of electric shock or energy hazards:
• This equipment must be installed by trained service personnel in a
restricted-access location, as defined by the NEC and IEC 60950-1,
First Edition, The Standard for Safety of Information
Technology Equipment.
• Connect the equipment to a properly grounded safety extra low
voltage (SELV) source. A SELV source is a secondary circuit that
is designed so that normal and single fault conditions do not
cause the voltages to exceed a safe level (60 V direct current).
• Incorporate a readily available approved and rated disconnect
device in the field wiring.
• See the specifications in the product documentation for the
required circuit-breaker rating for branch circuit
overcurrent protection.
• Use copper wire conductors only. See the specifications in the
product documentation for the required wire size.
• See the specifications in the product documentation for the
required torque values for the wiring-terminal screws.
To install a 750-watt -48 V to -60 V dc power supply, complete the following steps:
1. Touch the static-protective package that contains the power supply to any unpainted metal surface on
the server; then, remove the power supply from the package and place it on a static-protective surface.
2. Make sure that the circuit breaker for the dc power supply is off.
3. Attach the dc power cable to the new power supply. Make sure that the power cable wires are
connected securely to the -48 V, ground, and to the -48 V return terminals (as shown in the following
illustration).

4. Facing the rear of the server, insert the power supply spacer into the left side of the power-supply bay
(against the bay wall) against the wall on the left side of the power supply bay, if you removed it.
