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
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.
