Introduction
Congratulations on your purchase of a BEST 510 Uninterruptible Power
System (UPS)! We trust you will find it to be a valuable peripheral for
your electronic equipment. Please take just a few moments to read this
manual to obtain the maximum benefit from this product.
The BEST 510 UPS is an advanced sinewave UPS which is designed to
filter surges and sags that could potentially harm your equipment. It is
specifically engineered to protect a wide variety of systems, ranging from
computers and communication systems to industrial equipment. Under
normal AC utility power, the UPS filters out all small fluctuations. During
AC power failure, or if line voltage exceeds proper levels, the BEST 510
will automatically transfer to battery without any interruption to your
equipment. If the line voltage is low, it regulates incoming voltage to the
appropriate level without depleting the battery.
The UPS is equipped with many features which will make both your
equipment and UPS operation more reliable. See Table 1 below.
If the commercial line is frequently or
constantly low, the booster will lift the
output voltage to normal without draining
the internal battery.

Automatic function and
battery test
This test is performed whenever the UPS is
turned on. It tests the function of the UPS
and the batteries status, thus preventing
unforeseen problems.
The DB-9 communication port provides a
signal to link with computers. Further
details are on pages 15-16 of this manual.
SNMP ready.
Computer communication
The UPS can operate in either a 50 or 60 Hz
environment. The UPS will automatically
select the correct frequency for your
environment.
The UPS will switch to backup mode and
provide power from its internal battery when
input line voltage is too high.
