INTRODUCTION
SAVE THESE INSTRUCTIONS
Please read and save this manual!
The on-line series of Uninterruptible Power Supply (UPS) provides continuous and
power to the electronic equipments. It protects against blackouts, brownouts,
voltage fluctuations, power surges, spikes and line noises. During normal operation,
the UPS rectifies the commercial AC power and eliminates any voltage fluctuations
and transients noise before directing the power to the DC Bus. The inverter then
converts the DC power into pure AC for the output.
When a voltage drop is detected, the UPS will switch from normal operation to
backup mode in which the batteries will supply the power to the equipments. As
soon as the commercial power resumes to a suitable voltage level, the UPS will
again route and condition the power to the equipment through the DC Bus. In the
meantime, the batteries will get recharged. During the whole operation, no transfer
time takes place from normal AC to backup or vice versa, and hence is called the
true ON-LINE UPS system.
To protect your equipment, UPS will transfer to bypass mode when overload or
inverter failure. It will automatically transfer back to inverter when overload is
removed.
1. IMPORTANT SAFETY INSTRUCTIONS
