INSTALLATION INSTRUCTIONS
2.1
General Description
BORIS is a fast transfer line-interactive uninterruptible power supply. It is designed to
prevent blackouts, brownouts, sags, swells and surges from reaching the protected load
under normal conditions. It filters out small utility line fluctuations and isolates the
protected load from large disturbances by internally disconnecting from the utility line, while
supplying power from its internal batteries until the utility line returns to normal.
While operating on battery, an internal alarm will intermittently beep. The ON/TEST
button may be pressed to silence the alarm. If the line utility does not return and the
battery continues to power the protected load, a low battery shutdown may occur. Advance
warning of a low battery condition begins approximately two minutes before the final
shutdown. This alarm will be a continuous beeping sound and cannot be silenced. When
used with a Virginia Controls controller, this condition should not occur (if batteries were
previously charged fully) since the controller utilizes the remote shutdown capability of
BORIS.
Special features include surge protection; EMI/RFI filtering, high and low voltage
correction (without draining batteries), as well as automatic battery testing during power up
and every 14 days thereafter. User-replaceable batteries can be replaced without having to
remove power from the loads.
2.2
Location Factors
BORIS is intended for use in a protected environment. Avoid locations where
temperatures exceed 40°C (104°F) or fall below 0°C (32°F) as it will shorten battery life
and discharge time respectively. Do not locate BORIS in an environment, which may
contain excessive dust, dirt, chemicals, toxic gases, etc. Do not block vents located on the
sides of the unit.
2.3
Storage
If it is desired to store BORIS for an extended period, an optional power cord is available
which enables the batteries to be charged by connecting the unit directly to a wall outlet
(120 VAC). Batteries should be charged for 3 hours every 6 months. Repeat every 3
months in hot locations. Store in a cool, dry environment below 29.4°C (85°F).
