The two top pins are voltage inputs. The bottom pin is ground. As shown
in Figure 10, the top input voltage pins are labeled A and B, from left to
right, and the bottom pins are labeled C. Confirm the following
measurements:
 The voltage from A to A or B to B should be less than 4 V.
 The voltage from A to B or B to A should be between 200 and 240 V.
 The voltage between any A or B pin to either C pin should be about
120 V.
Power Rating
Each library frame is rated at 200-240 VAC at 13 amps (2600 watts
maximum). This power rating is based on a main frame with 24 LTO drives
and 6 RIMs, which is the configuration for maximum power consumption
by a single frame. The frames are not rated at 120 VAC due to the high
current required to supply the product.
Power Cord Specifications
The power cords included with the library are considered part of the
library and are not intended for use with any other equipment. See Supply-
End Connector Types on page 27 for the different types of cords available
from Spectra Logic.
Notes:  The supply-end connector is considered the disconnect for
the unit. Make sure that the socket-outlet for the AC
connection is in an accessible location near the library.
 The power cord must meet the specifications for the country
where the library will be installed.
