Theory of Operation
2–13
WARNING
Hazardous voltages are present inside the equipment cabinet and
the storage enclosure. Installation and service must be performed
only by qualified Digital Services engineers.
The ac power switch for the storage enclosure is in the center of the rear
panel. Setting the ac power switch to the (1) position applies power to the
storage enclosure. Setting the switch to the (0) position removes power
from the enclosure.
As you face the rear panel, the line voltage selector switch is located to
the right of the ac power switch. It is visible through a hole in the rear
panel. The Digital Services engineer sets this switch to the available line
voltage during installation. The number
120
represents 120 Vac at 60 Hz,
and the number
240
represents 240 Vac at 50 Hz.
CAUTION
The storage enclosure power supply is universal for both 120
Vac and 240 Vac. The supply is factory-set to 240 Vac and must
be reset to 120 Vac for some installations. Selecting 120 Vac and
using 240 Vac will damage the power supply.
The power supply fault indicator is behind the panel, in the lower right
corner of the storage enclosure. When the fault indicator is lit, a red
light is visible through the holes in the rear panel. The storage enclosure
automatically shuts down when the dc power supply detects a fault or
overtemperature condition.
