ETA Systems ® - SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
1100 and 1440 VA models: Receptacles 1 and 2 are Bank 1 and LEDs 1 and 2 will either be on
together or off together. Receptacles 3 and 4 are Bank 2 (LED 3) and receptacles 5 and 6 are Bank 3
(LED 4). It is possible to control Bank 1, Bank 2, and Bank 3 independently from each other.
Site Wiring Fault Indicator – (North American Versions Only)
A red Site Wiring Fault LED is located on the rear panel of the UPM. This LED is designed to illuminate if
the UPM is connected to an improperly wired AC receptacle. This indicator is designed to indicate a missing
safety ground wire or a reversal in phase and neutral wiring. This indicator should be visually checked
during installation and, if illuminated, you should contact a qualified electrician immediately.
Note: Do not operate the UPM if the Site Wiring Fault LED is illuminated. When lit, the LED is indicating a
wiring condition, which may represent a hazard of fire or electrocution. In addition, improper wiring may
create reliability problems for both the UPM and the connected system. Never use a 3 blade to 2-blade
adapter (often called a "cheater") with the UPM. These devices remove the safety ground connection to the
UPM and will cause the Site Wiring Fault LED to illuminate.
Communication Manager Port
Communication Manager provides a connection point on the rear panel of the UPM (both DB9 and USB
ports). Connecting to this port and installing Communication Manager's software package (optional), will
allow you control over important UPM functions and access to operating information from the UPM. Using
Communications Manager's software, you can view such parameters as AC input and output voltage,
powerline frequency, and battery voltage. The following table illustrates the available parameters.

Temperature
Communications Manager also can support simple software programs that rely on basic "contact closure"
signaling from the UPM. An example would be the built in UPS Service provided in Windows® NT. The
functions of basic software control usually include the following:
Indicates the actual input voltage to the UPM
when AC power is present
Indicates the actual output voltage of the UPM
Indicates the actual output frequency of the UPM
Indicates the actual DC voltage of the internal
battery buss
Indicates the battery is incapable of holding a
charge and requires replacement
Indicates the percentage of VA capacity being
used by connected load
Indicates the actual internal temperature of the
UPM
