CAUTION:
If the reading is other than infinity, do not proceed! Have the customer
make necessary wiring corrections before continuing. Do not turn on the
branch circuit circuit breaker until all the above steps are satisfactorily
completed.
6. Have the customer turn on the branch circuit circuit breaker. Measure for
appropriate voltages between phases. If no voltage is present on the receptacle
case or grounded pin, the receptacle is safe to touch.
7. With an appropriate meter, verify that the voltage at the outlet is correct.
8. Verify that the grounding impedance is correct by using the ECOS 1020, 1023,
B7106, C7106, or an appropriately approved ground impedance tester.
Note: Do not use the 120-volt convenience outlets inside a machine to power
the tester.
9. Skip to “Step 6.4. Connect the Power Distribution Bus.”
Step 6.4. Connect the Power Distribution Bus
1. Most systems in Model S00 racks are preconfigured in the factory with all
drawers and devices properly cabled and connected to the power distribution
bus. If this is not the case, plug any unconnected drawer power cables into the
outlets on the rear of the power distribution bus. For information about
connecting drawer and device power cables, see the installation or service guide
for the system or devices installed in your rack.
2. Plug the power distribution bus power cable into the customer's electrical outlet
or power cable.
3. Skip to “Step 7. Connect Drawer and Device Cables” on page 2-35.
