1. Introduction
The information provided in this manual covers single phase 1000 – 1200 VA
uninterruptible power systems. Included in this manual is information on the
installation, operation, safety precautions, shipping, and storage of the equipment.
Installation must be carried out in accordance with this manual. Electrical
installations must also follow local legislation and regulations. Only qualified
personnel should install this equipment. Failure to comply with the warnings and
precautions could prove to be fatal.
2. System Description
The purpose of the UPS is to protect sensitive systems from poor quality utility
power, complete loss of power, or other associated problems. System types include
computers, workstations, process control systems, telecommunications systems, sales
terminals, or other critical instrumentation.
Electrical interference may occur causing problems in AC power. Interference may
come from lightning, the power company, radio transmissions, or motors. Normal
operation of sensitive electrical equipment requires protection against power outages,
low or high voltage levels, frequency variations, differential and common-mode
noises, and transients.
In order to prevent power line problems from reaching critical systems and causing
damage to software, hardware or causing equipment to malfunction, the UPS helps
by maintaining a constant voltage, isolating critical load output, and cleaning the
utility AC power.
