Yes: Go to step 15 (See page 58).
v
DANGER
Dangerous voltage being measured. (RSFTD005)
No: Use a multimeter to measure the ac voltage at the customer's ac power outlet.
v
Is the ac voltage from 200 V ac to 240 V ac or from 100 V ac to 127 V ac?
–
No: Inform the customer that the ac voltage at the power outlet is not correct.
This ends the procedure.
–
Yes: Continue with the next step.
5.
Is the mainline ac power cable from the AC module, battery charger, power supply or power
distribution unit to the customer's ac power outlet connected and seated correctly at both ends?
No: Connect the mainline ac power cable correctly at both ends.
v
This ends the procedure.
v
Yes: Continue with the next step.
6.
DANGER
Dangerous voltage being measured. (RSFTD005)
Perform the following:
a.
Disconnect the mainline ac power cable from the AC module, battery charger, power supply or
power distribution unit.
b.
Use a multimeter to measure the ac voltage at the AC module, battery charger, power supply or
power distribution unit end of the mainline ac power cable.
Is the ac voltage from 200 V ac to 240 V ac or from 100 V ac to 127 V ac?
Yes: Go to step 9 (See page 57).
v
v
No: Continue with the next step.
7.
Are you working on a power distribution unit with tripped breakers?
Yes: Reset the tripped power distribution breaker and go to the power problem procedure for the
v
unit that is connected to the tripped breaker.
No: Continue with the next step.
v
8.
Exchange the mainline ac power cable or power distribution unit (as installed).
This ends the procedure.
9.
Does the unit you are working on have ac power jumper cables installed? (ac power jumper cables
connect from the AC module, battery charger unit, or the power distribution unit to the power
supplies.)
No: Go to step 14 (See page 58).
v
Yes: Continue with the next step.
v
10.
Are the ac power jumper cables from the AC module, battery charger unit, or power distribution unit
to the power supplies connected and seated correctly at both ends?
No: Connect the ac power jumper cables correctly at both ends.
v
This ends the procedure.
v
Yes: Continue with the next step.
11.
DANGER
Dangerous voltage being measured. (RSFTD005)
Perform the following:
