SOLA 610 UPS Installation
Electrical equipment is often rated in VA (volt-amps). This
represents the rated voltage times the rated current, i.e. 230
Volts x 2 Amp = 460VA.
Check your equipment for the manufacturer’s label. This label
should state the equipment’s desired operating voltage (V) and
current (A) drawn by the equipment. The manufacturer’s label is
usually found on the external rear or underside of the equipment,
or in the handbook or operator’s manual.

2.1 Introduction and Product Description
2.2 Sizing your Load
An Uninterruptible Power System is designed to connect between
your utility supply wall outlet or distribution board
and your critical load. Its function is to continually
monitor the availability and quality of the electrical
supply and to recreate the mains voltage to remain
within the UPS specifications, as detailed for each
model.
Your SOLA 610 is an advanced true on-line sine
wave UPS with bypass line, utilising double
conversion technology.
The utility power enters the UPS where it is
rectified to a DC voltage which will float charge the
battery as well as run the DC to AC inverter. The
inverter generates the true sine wave output,
recreating the utility supply voltage. A bypass path
is provided through a transfer switch, should the
UPS become overloaded or an inverter fault occur.
Because the UPS is an on-line design, conditioned power is provided
continuously to your load. During an electrical power failure, the unit
employs its internal maintenance free battery to supply continuous
power for as long as the battery is capable. The UPS autonomy after
a power failure will depend on (a) the size of the UPS and the load of
your equipment (b) the size of the battery used (either the standard
internal battery or external battery pack options), and (c) the state of
the battery and battery charge when the power failure occurs.
Batteries have a finite life that can be affected by excessive use and/
or high ambient temperatures. Under normal operation, you should
expect a 3-5 year life from your UPS battery.
