Power Configuration Options
Library Overview 1-11
AC Power Connections
AC wiring from the power source branch circuit must be installed in conduit (flexible
or rigid) with a 90-degree elbow-down fitting. If plugs and connectors are required
instead of using conduit, the table below lists the Hubbell part numbers (or
equivalent) to use.
Circuit Breaker Ratings
The minimum circuit breaker ratings required for the service panel are listed in the
tables below. Wire size should be determined by the electrician.
DC Power Supplies
The tape drives and robots use the same 1200W DC power supplies. The number of
DC load sharing power supplies required depends on the library configuration and
power options selected. Use the tables below to determine the number of power
supplies to order. For ordering information, see "Power Configurations" on page 1-23.
