Congratulations on your choice of the Sola/Hevi-DutyS4K5U6000-5 Uninterruptible Power System
(UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.
Upon generation, AC power is clean and stable. However, during transmission and distribution it
may be subject to voltage sags, spikes, or complete power failure that may interrupt computer opera-
tions, cause data loss, or even damage equipment. The S4K5U protects equipment from these distur-
bances.
The S4K5U comes in nominal power ratings of 4500 VA and 6000 VA. Complete model specifications
appear at the end of this manual.
The S4K5U is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its out-
put voltage, whether mains power is present or not. It supplies connected equipment with clean sine-
wave power. Sensitive electronic equipment operates best from sinewave power.
For ease of use, the S4K5U features a light-emitting diode (LED) display to indicate both load per-
centage and battery capacity. It also provides self-diagnostic tests, a combination ON/Alarm Silence/
Manual Battery Test button, a Standby button, user configurable program, and two levels of alarms
when the unit is operating on battery.
The S4K5U has an interface port for communication between the UPS and a network server or other
computer systems. This port provides detailed operating information including voltages, currents,
and alarm status to the host system when used in conjunction with Sola/Hevi-Duty MultiLink™ soft-
ware. MultiLink software can also remotely control UPS operation.
