Product Introduction
Thank you for selecting this Uninterruptible Power Supply (UPS). It provides you with protection for connected
equipment. Please read this manual before installing the S70 Series UPS models S70-500, S70-700, S70-1000,
S70-1500, and S70-2000 as it provides important information that should be followed during installation and main-
tenance of the UPS and batteries, allowing you to correctly set up your system for the maximum safety and per-
formance. Included is information on customer support and service, if it is required. If you experience a problem
with the UPS, please refer to the Troubleshooting section in this manual to correct the problem. If the problem is
not corrected, please collect information so that the Technical Support personnel can more effectively assist you.
Product Overview
Many different kinds of sensitive electrical equipment can be protected by an Uninterruptible Power Supply (UPS)
including computers, workstations, process control systems, telecommunications systems, sales terminals, other
critical instrumentation, etc. The purpose of the UPS is to protect these systems from poor quality utility power,
complete loss of power, or other associated problems.
Electrical interference exists in many forms, causing problems in AC power, from lightning, power company ac-
cidents and radio transmission motors, air conditioners, and vending machines. Protection of sensitive electrical
equipment is vital to protect against power outages, low or high voltage conditions, slow voltage fluctuations,
frequency variations, differential and common-mode noise, transients, etc.
To prevent power line problems from reaching critical systems causing damage to software, hardware, and equip-
ment malfunctions, the UPS maintains constant voltage, isolating critical load output and cleaning the utility AC
power.
Line Interactive Technology
A line interactive technology UPS provides basic power protection and Automatic Voltage Regulation (AVR) to the
load when AC input power is available. When AC input power is unavailable, the line-interactive UPS will switch to
batteries to supply the load with power. In the event that the power failure lasts longer than the UPS backup time,
the UPS will shut down avoiding battery damage. When the input AC voltage returns, the UPS will automatically
return online to recharge the batteries.
• AC input flows into and through the AVR to the load.
• When AC input varies outside the acceptable specification, the AVR switches taps on the transformer to
better regulate the output.
• If AC input power fails, the inverter turns on an supplies power from the batteries to the load.
• When AC input power returns, the UPS automatically begins supplying the load with power through the
AVR circuit.
• The charger circuit provides recharge for the batteries.
