Initial Actions
Disconnect the AC power cord from the wall outlet.
WARNING
Improper connection of the grounding conductor can result in the risk of electrical
shock. The following must be observed:
• Never use a ground adapter plug to connect the machine to a power source.
• Never attempt any maintenance function which is not specifically called out in the
service procedures.
• Never remove any covers which are fastened with screws, unless so instructed in
the service procedures.
CAUTION
If any of the voltage measurements are not as specified in the following steps, the cause must
be corrected. Caution the customer NOT to connect the machine to the wall outlet. Advise the
customer that a licensed electrician must correct the wiring. Do not attempt to correct the wir-
ing yourself. If you later find the condition has not been corrected, inform your manager in writ-
ing of the improper wiring.
Procedure
Perform one of the following line voltage checks:
US, XCI, and AO (115 VAC)
Figure 1 . Perform the following:
Measure the AC voltage between AC Line and Neutral, between AC Line and Ground, and
between AC Neutral and Ground. The voltage between Line and Neutral and between Line and
Ground is 90 to 140 VAC and the voltage between Neutral and Ground less than 3 VAC.
Figure 1 US, XCI, and AO (115 VAC) Outlet.
XL, UK and AO (220 VAC) Figure 2 . Perform the following:
Measure the AC voltage between Line and Neutral, between Line and Earth/Ground, and
between Neutral and Earth/Ground. The voltage between Line and Neutral and between Line
and Earth/Ground is 198 to 264 VAC and between Neutral and Earth/Ground is less than 3
VAC.
Figure 2 XL, UK, and AO (220 VAC) Outlet.
XL, Europe (220 VAC) Figure 3 . Perform the following:
Measure the AC voltage between the supply pins, then between a supply pin and earth, then
between the other supply pin and earth. The voltage is 198 to 264 VAC between the supply
pins and between one of the supply pins and earth. Between the other supply pin and earth is
less than 3 VAC.
Figure 3 XL, Europe (220 VAC) Outlet.
The voltage measured is correct.

Inform the customer of insufficient voltage or improper wiring.
Check the continuity through all connections of the power cord. The measurement is less
than 10 ohms for each connection.
