(see Notes 1, 2,
and 5.) Power cord for EMEA:
3-phase 50 Hz 35
amperes Not applicable Hard-wired

(see Notes 1, 2,
4, 5, and 6.) Power cord for Japan,
U.S., and Canada:
3-phase 50 Hz or 60
Hz, 60 amperes IEC 309 IEC 309
Notes:
1. All power cords are rated at 600 V ac, except power cords for Japan, which are 250 V
ac. Each cord has 3 poles and 4 wires.
2. The conductor size for non-EMEA and Japan power cords is 6 awg. The conductor size
for EMEA cords is 6 mm
² .
3. Connectors and receptacles are supplied by Russellstoll.
4. Preferred connectors and receptacles are supplied by Hubbell.
5. All power cords extend 4.2 m (14 ft) from lowest point where they exit the frame to the
mating face of the plug or bare leads.
6. The IEC309 receptacle must be installed in a metal-backed box with the green wire
ground-connected to the grounding lug within the box. Ensure continuity between the
box and the metallic shielding of the liquid-tight conduit.
7. The 7428-78 in-line connector must have the appropriate JPA adapter that is included in
the assembly. The adapter ensures continuity between the connector housing and the
metallic shielding of the liquid-tight conduit.
8. Single-phase power is supported on Models 951 and 95E. To inquire about single-phase
power support on your existing models, contact your IBM representative.
Power consumption and environmental information
When you are planning to meet the power requirements for the DS8000 series,
consider the power consumption and other environmental points of the storage
unit.
This power consumption and environmental information for the various DS8000
models is provided in Table 56 and Table 57 on page 164.
