NTRODUCTION
Congratulations on your choice of the Sola/Hevi-Duty S3K2U Uninterruptible Power Supply (UPS). It
provides conditioned power to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission it may be subject to
voltage sags, spikes, or complete power failure which may interrupt computer operations, cause data
loss, or even damage equipment. The S3K2U protects equipment from these disturbances.
The S3K2U comes in nominal power ratings of 1000, 1440, 2200, or 3000 VA. Refer to 12.0 - Specifi-
cations (Sechnische Daten) for details.
The S3K2U is a 2U, line-interactive UPS that may be installed in a rack or used in a tower configura-
tion. A line-interactive UPS continuously conditions and regulates its output voltage, whether mains
power is present or not. It supplies connected equipment with clean, sinewave power to simulate the
power generated by the mains. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the S3K2U contains Status Indicators to display Load Level, Battery Level, Buck/
Boost, Over Temperature and Battery. It also provides self-diagnostic tests, a combination ON/Alarm
Silence/Battery Test button, an OFF button and Voltage Programming button.
The S3K2U has USB, DB-9 (RS232/contact closure) and Intellislot interface ports for communications
between the UPS and a LAN server or other computer systems. The DB-9 port provides detailed oper-
ating information including voltages, currents, and alarm status to the host system when used in con-
junction with MultiLink software. MultiLink software can also remotely control UPS operation. The
USB port provides detailed operating information and alarm status to the host system when used in
conjunction with Microsoft Power Manager software.
