DS8000 Service Documentation Version 6.3.3
Checking customer voltage with customer CB on (wired)
Procedure
- Measure the voltage between the ground pin and each voltage
pin (for three phase A , B ,
and C or
for single phase A and B ) on
each mainline power cable. Refer to Figure 1 or Figure 2. For the top exit line
cord feature, refer to Figure 3 and Figure 4.
Are the voltages within 10% of each other?
- Yes, continue with the next step.
- No, inform the customer that the voltages are not correct. Do not continue until the voltages are correct.

- Locate the agency label on the inside
front left wall of the rack, halfway from the top (near the front
of PPS E2). See Figure 5.
The label will include the voltage, current, and phase specifications
for this model. Measure the voltage between each pair of voltage
pins (for three phase A to B , B to C ,
and C to A ; or for single phase A to B )
on each mainline power cable. Refer to Figure 1 or Figure 2. For the top exit line
cord feature, refer to Figure 3 and Figure 4. Verify
that the customer AC input voltage that you just measured matches
the machine input voltage information on the label.
Does the voltage measured match the voltage on the DS8000® information label?
- Yes, continue with Connecting the mainline power cables on the racks (wired).
- No, do not continue with the installation. Contact the marketing representative to confirm that the DS8000 was ordered with the correct power input feature.
