Smart-UPS 750/1000/1500/2200/3000 VA 120/230 Vac Tower / Rack-Mount 2U 21
Normally closed contacts
1. 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.
2. 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 milliAmps 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.
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.
Battery Replacement
Always recycle used batteries.
For information on recycling a used battery, refer to the Battery Disposal
Information sheet included with the replacement battery.
Battery life is highly dependent on temperature and use. To identify when to replace batteries, Smart-UPS have a
predictive battery replacement date indicator in the “About” menu and automatic (and configurable) self-tests.
Proactively replace batteries to maintain the highest availability. To ensure protection and high performance, use
only genuine APC replacement battery cartridges (RBC™). The APC RBC contains instructions for battery
replacement and disposal. To order a replacement battery go to the APC by Schneider Electric Web site,
www.apc.com.
