LIFE SUPPORT APPLICATION POLICY
As a general policy, APC does not recommend the use of any of its products in life support applications where failure or malfunctions of the APC product can be reasonably expected to cause failure
of the life support device or to significantly affect its safety or effectiveness. APC does not recommend the use of any of its products in direct patient care. APC will not knowingly sell its products
for use in such applications unless it receives in writing assurances satisfactory to APC that (a) the
risks of injury or damage have been minimized, (b) the customer assumes all such risks, and (c) the
liability of APC is adequately protected under the circumstances.
Examples of devices considered to be life support devices are neonatal oxygen and analyzers, nerve
stimulators (whether used for anesthesia, pain relief, or other purposes), autotransfusion devices,
blood pumps, defibrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis systems,
peritoneal dialysis systems, neonatal ventilator incubators, ventilators for both adults and infants,
anesthesia ventilators, infusion pumps, and any other device designated as “critical” by the
U.S.F.D.A.
Hospital grade wiring devices and leakage current may be ordered as options on many APC UPS
systems, APC does not claim that units with this modification are certified or listed as Hospital
Grade by APC or any other organization. Therefore these units do not meet the requirements for use
in direct patient care.

UNPACKING
1. Inspect the battery pack upon receipt. APC designed robust packaging for your product. However, accidents and damage may occur during shipment. Notify the carrier and dealer if there is
damage.
The packaging is recyclable; save it for reuse or dispose of it properly.
2. Check the package contents. The shipping package contains the battery pack, its front bezel
(packaged separately), mounting rails, mounting cleats, hardware packet (necessary for rack
mounting), and a literature kit containing product documentation.
The battery pack is shipped with the front bezel removed (packaged separately within
the main box). You will install the plastic bezel (described later) during the installation
procedure.
POSITIONING THE BATTERY PACK
Place the rack and the battery pack where they will be used. The battery pack is heavy. Select a
location sturdy enough to handle the weight.
Consider that you must install the battery pack in a protected area that is free of excessive dust and
has adequate airflow. Ensure the air vents on the front and rear of the battery pack are not blocked.
Allow at least one inch of space on both sides.
Do not operate the UPS where the temperature and humidity are outside the specified limits. Refer to
Specifications at the APC web site.

OPERATING THE SMART-UPS WITH A BATTERY PACK
SETTING THE SMART-UPS TO RECOGNIZE THE BATTERY PACK(S)
Smart-UPS XL models cannot determine how many external battery packs are connected to them.
You must program the Smart-UPS XL with the appropriate number of external batteries in one of
four ways using:

Smart-UPS Battery Pack Utility (BATTPACK)
PowerChute® plus Version 5.x for Windows 95, Windows 98, Windows NT
Terminal Program to Change the Number of External Battery Packs
HyperTerminal Program to Change the Number of External Battery Packs
Each method is described in this section.
It is important to follow these instructions. The number of batteries affects the run time
calculations the Smart-UPS performs when it is running on battery power.
USING THE SMART-UPS BATTERY PACK UTILITY (BATTPACK)
You can use the BATTPACK program with DOS or at a Microsoft® Windows DOS prompt. BATTPACK cannot be used with a DOS emulator or VDM (virtual DOS machine) like those in Windows
95, Windows 98, or Windows NT.
You must use the APC UPS Link cable to communicate to the UPS. Use either of two black cables:
part numbers 940-0024C or 940-1524C.
At the DOS prompt, type:
battpack com[X] [Y]
where [X] represents the available serial port the Battery Pack Utility uses to access the Smart-UPS.
[Y] represents the number of external battery packs.
In the following example, the black cable is attached to communication port 1. There are four external battery packs. The program confirms that the update is successful.

STORAGE AND REPLACEMENT
STORAGE
STORAGE CONDITIONS
Store the battery pack covered and flat (rack mount orientation) in a cool, dry location, with its battery fully charged. Disconnect any cables connected to the computer interface port to avoid unnecessarily draining the battery.
EXTENDED STORAGE
At -15 to +30 °C (+5 to +86 °F), charge the batteries every six months.
At +30 to +45 °C (+86 to +113 °F), charge the batteries every three months.
REPLACING A BATTERY TRAY
The battery pack has two easy to replace, hot-swappable battery trays. Battery tray replacement is a
safe procedure, isolated from electrical hazards. You may leave the battery pack connected to the
UPS with the protected equipment on for the following procedure. See your dealer or contact APC
for information on replacement battery tray (RBC-27). See the APC website http:// www.apc.com
/support, to confirm the correct replacement battery tray number (RBC) and to see other options.
BATTERY TRAY REPLACEMENT PROCEDURE
The battery trays are accessible from the front of the
battery pack. This procedure requires a Phillips screwdriver.
1. Remove the front bezel. Use both hands and grasp
the finger clips on either side of the bezel. Pull it toward you. The bezel will unsnap from the battery
pack.
Set the bezel aside—you will reinstall it later.
Although both battery tray compartments are visible,
Steps 2 through 11 describe how to remove and replace
one battery tray. Repeat the steps for the other tray.

SERVICE
If the unit requires service, do not return it to the dealer. Instead, follow these steps:
1. Review the problems discussed in the Troubleshooting section of the User’s Manual for your
UPS to eliminate common problems.
2. Verify that no circuit breakers are tripped. A tripped circuit breaker is the most common problem.
3. If the problem persists, call APC Customer Service or visit the APC website (www.apc.com).
n
n
n
Note the model number of the unit, the serial number, and the date purchased. If you call APC
Customer Service, a technician will ask you to describe the problem and try to solve it over
the phone, if possible. If this is not possible the technician may arrange for the unit to be serviced or may issue a Returned Material Authorization Number (RMA#).
If the unit is under warranty, repairs are free. If not, there is a repair charge.
Procedures for servicing or returning your unit may vary internationally. Please contact the
APC Customer Service office in the appropriate country (www.apc.com/support) for questions about warranty and RMA.
4. Pack the unit in its original packaging. If the original packing is not available, ask APC Customer
Service about obtaining a new set.
