1. Indicating LED’s:
a. Load On: When green, this LED shall indicate the load is being supported by the UPS
output.
b. On Battery: When yellow, this LED shall indicate the UPS is running from battery
power.
c. Bypass: When yellow, this LED shall indicate the load is being supported by static
bypass/mechanical bypass.
d. Fault: When red, this LED shall indicate there is a fault condition present in the UPS.
2. Pushbutton User Controls:
a. Up arrow.
b. Down arrow.
c. Help key.
d. Escape key.
e. Enter key.
G. Potential Free (Dry) Contacts: The following potential free contacts shall be available on an
optional relay interface board (AP9610 or equivalent) (note, this may require the use of an
external chassis if used in conjunction with web-based management or other smart-slot type
devices):
1. Normal operation.
2. Battery operation.
3. Bypass operation.
4. Common fault.
5. Low battery.
6. UPS off.
H. Communication Interface: For purposes of remote communications with the UPS the following
shall be available and contained within the UPS on a removable, hot-swappable smart-slot

or APC InfraStruXure Manager.
2. Environmental monitoring feature, capable of locally monitoring temperature and humidity as
well as one additional generic set of Owner-determined dry contacts capable of taking an
input signal from any APC or third party on/off signal, such as water detection, smoke
detection, motion, or fire detection.
2.8 BATTERY
A. The UPS battery shall be of modular construction made up of Owner-replaceable, hot swappable,
fused, battery modules. Each battery module shall be monitored to determine the highest battery
unit temperature for use by the UPS battery diagnostic, and temperature compensated charger
circuitry.
B. The battery jars housed within each removable battery module shall be of the valve regulated lead
acid (VRLA) type.
2.9 ACCESSORIES
A. Extended Runtime (XR) Option:
1. For purposes of extending the UPS battery runtime, external extended runtime options shall be
available. The extended runtime option shall be housed in line-up-and-match type enclosures
and shall contain necessary hardware and cables to connect to the UPS, or between XR
enclosures. Each XR enclosure shall be equipped with removable, hot swappable, battery
units housed in draw-out cartridges.
2. The extended runtime system shall have a 250 volts DC rated, thermal magnetic trip molded
case circuit breaker. Each circuit breaker shall be equipped with shunt trip mechanisms and
