3.0 Introduction

Congratulations on your choice of the SDU Uninterruptible Power System (UPS).
The SDU is a compact, "Off-Line" DIN rail mountable UPS, which provides condi-
tioned power to sensitive electronic equipment. It supplies connected equipment
with stepped approximation to sinewave power to simulate the power generated
by the utility.
The SDU is a powerful, microprocessor-controlled UPS. Input voltage range is
80% to 110% (ideal protection for the critical connected loads). Battery charging
occurs automatically when ac power is applied, no need to switch ON the UPS.
When power fails, the UPS can be automatically turned OFF, as long as the
connected loads are not operating to save the battery energy. The SDU also
includes an automatic self-test feature to test the UPS function and battery. If the
battery is no longer useful, the unit will sound an alarm and an LED indicator will
illuminate.
NOTE: This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in an
industrial installation. This equipment uses, generates and can radiate radio
frequency energy and, if not installed and used in accordance with the instruc-
tions, may cause harmful interference with radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment OFF and ON, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the UPS and the receiver.
• Connect the UPS into a circuit different from that which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help.
