Description
Online
The UPS is drawing utility power and performing double conversion to supply
power to connected equipment (see Troubleshooting).
On Battery
The UPS is supplying battery power to the connected equipment.
Bypass
The UPS is in bypass mode, sending utility power directly to connected equipment.
Bypass mode operation is the result of an internal UPS fault, an overload condition
or a user initiated command either through an accessory or the manual bypass
switch. Battery operation is not available while the UPS is in bypass mode (see
Troubleshooting).
Fault
The UPS detects an internal fault (see Troubleshooting).
Overload
The connected loads are drawing more power than the UPS power rating (see
Troubleshooting).

Feature
Function
Normal /Bypass
Manually switch connected equipment to bypass mode, so that utility power is
sent directly to connected equipment. Battery operation is not available while
the UPS is in bypass mode. (See Troubleshooting.)
Cold Start
This is not a normal condition.
Supply immediate battery power to the UPS and connected equipment (see
Troubleshooting). Press and hold the
button to power up the UPS and
connected equipment. The UPS will emit two beeps. During the second beep,
release the button.
Self-Test
Automatic: The UPS performs a self-test automatically when turned on, and
every two weeks thereafter (by default). During the self-test, the UPS briefly
operates the connected equipment on battery.
Manual: Press and hold the

The UPS has a diagnostic feature that displays the utility voltage. Plug the UPS
into the normal utility power.
The UPS starts a self-test as part of this procedure. The self-test does not
affect the voltage display.
Press and hold the
button to view the utility voltage bar graph display.
After a few seconds the five-LED, Battery Charge
display on the right of
the front panel shows the utility input voltage.
Refer to the figure at left for the voltage reading (values are not listed on the
UPS).
The display indicates the voltage is between the displayed value on the list and
the next higher value.
On Battery Operation
The UPS switches to battery operation automatically if the utility power fails. While running on
battery, an alarm beeps four times every 30 seconds.
Press the
button to silence this alarm. If the utility power does not return, the UPS continues to
supply power to the connected equipment until the battery is fully discharged.
When two minutes of runtime remain the UPS emits a continuous beep. If PowerChute or the
Web/SNMP card is not being used, files must be manually saved and the computer must be properly
shut down before the UPS fully discharges the battery.
The UPS battery life differs based on usage and environment. Refer to www.apc.com/products for
on battery runtimes.

EPO (Emergency Power Off) Option
The output power can be disabled in an emergency by closing a switch connected to the EPO.
Adhere to national and local electrical codes when wiring.
The switch should be connected in a normally open switch contact. External voltage is not required;
the switch is driven by 12V internal supply. In closed condition, 2mA of current are drawn.
The EPO switch is internally powered by the UPS for use with non-powered switch circuit breakers.
The EPO circuit is considered a Class 2 circuit, (UL, CSA standards) and an SELV circuit (IEC
standard).
EPO
switch
Both Class 2 and SELV circuits must be isolated from all primary circuitry. Do not connect any
circuit to the EPO terminal block unless it can be confirmed that the circuit is Class 2 or SELV.
If circuit standard cannot be confirmed, use a contact closure switch.
Use one of the following cable types to connect the UPS to the EPO switch:
•
CL2: Class 2 cable for general use
•
CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air.
•
CL2R: Riser cable for use in a vertical run in a floor-to-floor shaft.
•
CLEX: Limited use cable for use in dwellings and for use in raceways.
•
For installation in Canada: Use only CSA certified, type ELC (extra-low voltage control cable).
•
For installation in other countries: Use standard low-voltage cable in accordance with local
regulations.
