Introduction
Power Supplies
MSL5000 series libraries support one or two power supplies that are accessible from
the rear of the unit (see Figure 1–3). These auto-ranging power supplies are capable of
using any nominal AC voltage between 100 VAC and 240 VAC power, at 50 Hz or 60
Hz, and are easily removed without requiring special tools.
Power to the library is supplied through AC connectors at the rear panel of each power
supply receiver. Library power is normally controlled from the Graphical User
Interface (GUI) touch screen; however, a manual power disconnect switch, located at
the rear of each power supply is provided.
CAUTION:
The power supply is not to be removed by the operator. Hazardous voltage
is present in the cavity if the power cord is not removed.
Power supplies can be easily replaced in maintenance/service mode using a #1 Phillips
screwdriver to remove the power supply bracket.
For the MSL5052/MSL5060 libraries, two power supplies are supported to provide
redundancy for mission critical operations. Both power supplies share the load under
normal operating conditions, however, if one of the power supplies fail the remaining
power supply assumes the full load (see Figure 1-3 on the following page).
