or until commercial AC power returns.
LED 5 Battery Weak: When this LED is illuminated, the battery requires either recharging or
replacement. If the LED remains illuminated after a 12-hour charge period, the internal battery
should be replaced.
LED 6 Overload: When this LED is illuminated, the UPM is overloaded. Remove load from the UPM by
determining, which of the connected pieces of equipment is the least critical, and disconnect it
from the UPM. Operating the UPM in an overloaded condition, may cause the UPM to protect
itself by shutting down and removing power unexpectedly to all connected components.
Configuration Manager Receptacle Indicators
The four clustered LEDs in the center of the front panel indicate the output receptacle status as controlled by
Configuration Manager. Configuration Manager addresses receptacle control differently for some of the
models (See following explanation).
350 VA models: Configuration Manager treats receptacles 1and 2 as a group (Bank 1) and receptacles
3 and 4 as a group (Bank 2). For these models, LED 1 and 2 (Bank 1) will either be on together or off
together. LEDs 3 and 4 (Bank 2) will also be on or off together. It is not possible to control receptacles
1 and 2 or receptacles 3 and 4 separately. It is only possible to separately control Bank 1 and Bank 2.
500 and 800 VA models: The top two receptacles are Bank 1 and the bottom four receptacles are Bank
2. On these models, LED 1 and 2 (Bank 1) will either be on together or off together. LEDs 3 and 4
(Bank 2) will also be on or off together. It is not possible to control receptacles 1 and 2 or receptacles 3,
4, 5 and 6 separately. It is only possible to separately control Bank 1 and Bank 2.
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.
