Smart-UPS X Series Uninterruptible Power Supply

Overview

About the UPS

The APC® by Schneider Electric Smart-UPS® X is a high performance uninterruptible power supply (UPS). It provides protection for electronic equipment from utility power blackouts, brownouts, sags, and surges; small utility fluctuations and large disturbances. The UPS also provides battery backup power until utility power returns to safe levels or the batteries are fully discharged.

The Smart-UPS X has both high and low voltage models

Low Voltage (100-127 V)
SMX2000RMLV2U
SMX2200RMLV2U
SMX3000RMLV2U
SMX3000RMLV2UNC
SMX3000RMJ2U

High Voltage (200-240 V)
SMX2200RMHV2U
SMX3000RMHV2U
SMX3000RMHV2UNC

Safety

Read the Safety Guide included in the package before installing the UPS.
Inspect the UPS upon receipt. Notify the carrier and dealer if there is damage.
Recycle the packaging.
Heavy: The external battery packs (XLBPs) are heavy. Always install the XLBPs at the bottom of the rack. Install the UPS above the installed XLBPs.

Switched Outlet Groups

Overview

The Switched Outlet Groups can be configured to independently turn off, turn on, shut down, put to sleep, and reboot connected equipment.

The Switched Outlet Groups can be commanded to do the following:

Turn off: Disconnect from power immediately and restart only with a manual command
Turn on: Connect to power immediately
Shutdown: Disconnect power in sequence, and automatically reapply power in sequence when utility power becomes available
Reboot: Shut down and restart
Sleep: Reboot after a long delay

In addition, the Switched Outlet Groups can be configured to do the following:

Turn on or off in a specified sequence
Automatically turn off or shut down when various conditions occur

Note: Whether the Switched Outlet Groups are configured or not, all of the outlets provide battery back-up power.

Using the Switched Outlet Groups

Connect critical equipment to a Switched Outlet Group.
Connect peripheral equipment to the other Switched Outlet Groups.
– During a power outage, to conserve battery runtime, non-essential equipment can be configured to shut down after a short delay
– If equipment has dependent peripherals that must restart or shut down in a specific order, such as an ethernet switch that must restart before a connected server, connect the devices to separate groups
– Equipment that needs to reboot independently from other equipment should be added to a separate group
Use the Configuration menus to configure how the Switched Outlet Groups will react in the event of a power outage.

Customize the Switched Outlet Groups

Use the Control menus to customize the Switched Outlet Groups.

Emergency Power Off

EPO Overview

he Emergency Power Off (EPO) option is a safety feature that will immediately disconnect all connected equipment from utility power. The UPS will immediately shut down and will not switch to battery power.
Connect each UPS to the EPO switch.
The UPS must be manually restarted to reapply power to connected equipment. Press ON/OFF on the front panel of the UPS.

Normally open contacts

If the EPO switch or relay contacts are normally open, insert the wires from the switch or contacts at pins 1 and 2 of the EPO terminal block. Use 16-28 AWG wire.
Secure the wires by tightening the screws.
If the contacts are closed, the UPS will turn OFF and power will be removed from the load.

Normally closed contacts

If the EPO switch or relay contacts are normally closed, insert the wires from the switch or contacts at pins 2 and 3 of the EPO terminal block. Use 16-28 AWG wire.
Insert a wire jumper between pins 1 and 2. Secure the wires by tightening the three screws at positions 1, 2, and 3.
If the contacts are opened, the UPS will turn OFF and power will be removed from the load.

Note: Pin 1 is the power source for the EPO circuit, it provides a few milliampere of 24 V power.

If the normally closed (NC) EPO configuration is used, the EPO switch or relay should be rated for “dry” circuit applications, the rating should be for low voltage and low current applications. This normally implies the contacts are gold-plated.

Adhere to all national and local electrical codes when wiring the EPO. Wiring must be performed by a qualified electrician.

The EPO interface is a Safety Extra Low Voltage (SELV) circuit. Connect the EPO interface only to other SELV circuits. The EPO interface monitors circuits that have no determined voltage potential. SELV circuits are controlled by a switch or relay properly isolated from utility power. To avoid damage to the UPS, do not connect the EPO interface to any circuit other than a SELV circuit.

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.
Installation in Canada: Use only CSA certified, type ELC, (extra-low voltage control cable).
Installation in countries other than Canada and the USA: Use standard low-voltage cable in accordance with national and local regulations.

Troubleshooting

Problem and Possible Cause	Solution

The UPS will not turn on or there is no output
The unit has not been turned on.| Press the ON button to trum on the UPS.
The UPS is not connected to utility
power.| Ensure that the power cable is securely connected to the unit and to the utility
power supply
There is an internal UPS fault.| Do not attempt to use the UPS. Unplug the UPS and have it serviced
immediately.
The UPS is operating on battery, while connected to input utility power
There is very high, very low, or distorted
input line voltage or frequency| Move the UPS to a different outlet on a different circuit. Test the input voltage
with the utility voltage display. If acceptable to the connected equipment,
reduce the UPS sensitivity.
Test the utility input power to ensure the unit is receiving input power
UPS emits an audible beeping sound at long intervals
The UPS is in normal operation.| The UPS is protecting the connected equipment. See the display interface to
view the status of the UPS.
UPS does not provide expected backup time
The UPS battery is weak due to a recent
outage or is near the end of its service
life.| Charge the battery. Batteries require recharging after extended outages and
wear out faster when put into service often or when operated at elevated
temperatures. If the battery is near the end of its service life, consider
replacing the battery even if the replace battery indicator is not yet
illuminated.
The UPS is overloaded.| Check the UPS load display. Unplug unnecessary equipment, such as printers.
The Fault indicator is lit and the UPS displays a fault message and emits a constant beeping sound
Internal UPS fault.| Do not attempt to use the UPS. Turn the UPS off and have it serviced
immediately.
The replace battery indicator is illuminated
The battery has a weak charge.| Allow the battery to recharge for at least four hours. Then, perform a self-test.
If the problem persists after recharging, replace the battery.
The replacement battery is not properly
connected.| Ensure that the battery connector is securely connected.
The display interface has a Site Wiring Fault message
Wiring faults detected include missing
ground, hot-neutral polarity reversal,
and overloaded neutral circuit.| f the UPS indicates a site wiring fault, have a qualified electrician inspect the
building wiring. (Applicable for Low Voltage (120 V) units only.)
