Power Source Disturbances; Power Entry - Qualstar RLS-8350 Installation And Operation Manual

MODEL
RLS-85XX
Table 3-4 RLS-85XX Power Consumption
Power consumption varies with the number of tape drives installed and the particular
operation being performed. Table 3-3 and Table 3-4 are based on a full complement of
tape drives installed in each model specified. The idle power figures indicate the
power consumed when the changer and tape drives are idle. The peak power figures
indicate the peak power consumed when the carriage accelerates and the tape drives
are active. The peak power levels are not expected to last for more than two seconds at
a time. The current drawn from the power line (mains) is equal to the watts indicted
in Table 3-3 and Table 3-4 divided by the AC voltage.
3.3.1

Power Source Disturbances

The RLS will continue to operate uninterrupted and without damage over a one-cycle
line dropout. It is recommended that the RLS be powered from an Uninterruptible
Power Source (UPS).
3.3.2

Power Entry

All RLS libraries have a line fuse and I.E.C. power receptacle mounted on the rear
panel. An internal AC line filter reduces EMI conducted emissions and protects the
RLS from any noise present on the power lines. A six-foot, seven-inch (2-meter) power
cord is supplied for 120 VAC use in North America. A Harmonized HO5VV-F power
cord is supplied for other destinations.
3.3.2.1 Replacing the Fuse
If you need to replace a fuse due to an equipment failure, first determine the cause of
the failure and solve the problem before replacing the fuse.
TO AVOID THE POSSIBILITY OF PERSONAL INJURY, BE SURE TO TURN OFF
THE RLS' POWER AND DISCONNECT THE POWER CORD BEFORE REPLACING A
FUSE.
The AC power receptacle on the rear of the library contains the fuse. When you pull
the fuse holder out it folds to the right so that the fuse can be easily replaced. (Be
careful not to pull the fuse holder with excessive force.) See Figure 3-3.
