Operation safety

WARNING!

- Hazardous electrically-charged parts inside the UPS are energized from the
battery supply even when the AC power is disconnected. Follow Total Power Off
procedure to completely de-energize the system.

- Remove all conductive jewel ry such as chains, wat ches, and rin gs befor e handling
the Battery Units.

- Battery Units do not contain serviceable parts. Do not open.

- Do not dispose of Battery Units in a fire, as they may explode. Do not mutilate
Battery Units, as released electrolyte is harmful to the skin and eyes and may be
toxic.

WARNING!
After the UPS has been electrically wired, do not start it up. Start-up is
commissioned to APC-authorized personnel only.

For configurations including customer-supplied external batteries, refer to
manufacturer’s battery installation and maintenance instructions.

Total Power OFF procedure

WARNING!
Before electrical installation begin s, verify that the UPS is in the Total Power Off
mode by following this procedure.

Shutdown Configure the following system shutdown conditions:

Low Batt Dur: Low battery duration is the time from low battery signal to the

shutdown of the load. This signal is sent to the server using shutdown software
(PC + PCNS).

Shutdwn Dly: Shutdown delay is the time from when the UPS receives a
shutdown command (usually sent by a server) to the shutdown of UPS power to
the load equipment. This delay allows load equipment to finish shutdown
processes.

Alarms Redundancy: The state of redundancy that will trigger an alarm. Choices are:

Bypass Set the conditions in which the UPS will automatically go into bypass operation.
Copy Copy the UPS settings.
Other Self Test: Set the UPS to perform a self-test automatically at periodic intervals.

• N+0 – an alarm will occur only when there is more load than all functioning
power modules can support;

• N+1 – an alarm will occur when there are no spare power modules in good
condition;

• N+2 – an alarm will occur when there is only one functioning power module.

Load: When the load is greater than this threshold, an alarm will sound.

Runtime: When the UPS time duration for powering the load is les s th an this

threshold, an alarm will sound. This alarm is the result of an increase in load or a
decrease in battery capacity.

USP ID: Type in a unique name for the UPS.

How to obtain replacement Modules

To obtain a replacement module, contact APC Customer Support.

1. In the event of a module failure , the displa y inte rface may di splay addi tional “f ault lis t” screen s.
Press any key to scroll through these fault lists, record the information, and relay it to the
customer support representative.

2. If possible, call APC Customer Support f rom a telepho ne that i s withi n reach of the UPS disp lay
interface so that you can gather and report additional information to the representative.

3. Be prepared to provide a detailed description of the problem. A representative will help you
solve the problem over the telephone, if possible, or will give you a return material
authorization (RMA) number. If a module is returned to APC, this RMA number must be
clearly printed on the outside of the package.

4. If the Symmetra PX UPS is within the warranty period, rep airs will be performed fr ee of charge .
If it is not within the warranty period, there will be a charge for repair. Review APC ‘s warranty
policy.

See section on Warranty for more information

5. If the UPS is covered by a n APC service c ontract , have th at informa tion avai lable and provide it

System Re-Start (if applicable)

System start-up is includ ed with your system. If you have to move your system to a new locati on and
need a new start-up, remove all power modules and follow the Total Power Off procedure. Raise the
stabilizing feet.

Secure the UPS by setting the stabilizing feet

After the electrical wiring has been completed, secure the UPS in its final operating position. Use a
13/14-mm wrench (shipped with UPS) to adjust all 4 stabilizing feet until pads make solid contact
with the floor.

Level the UPS (recommended)

Adjust stabilizing feet to level from front to back and left to right.

13/14-mm wrench

CAUTION!

Do not move the UPS after the stabilizing feet have been lowered, or equipment
damage may occur.

Life support policy

American Power Conversion Corporation (APC) and its affiliates and subsidiaries worldwide do not
recommend the use of any of their products in life-support applications where failure or malfunction
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 permit the use of any of its products in
direct patient care. APC will not knowingly sell its products for use in such applications unless the
life-support system or direct patient care device is part of a whole facility/building in to which the
UPS is integ r ated, and unless APC rece ives, in writing, assurances satisfact ory to APC tha t:

a. The UPS system will be configured in a manner that will provide N+1 power redundancy to

the critical load,

b. The end-user customer assumes all risks and signs the APC System Configuration and Use

Form, and

c. The customer and operators of the APC UPS system agree to indemnify and hold APC and

its affiliates and subsidiaries harmless for any and all claims arising out of the systems use in
such applications.

Examples of life-support devices include, but are not limited to, neonatal oxygen analyzers, nerve
stimulators (whether used for anaesthesia, pain relief, or other purposes), auto-transfusion devices,
blood pumps, defibrillators, arrhythmia detectors and alarms, pacemakers, hemodialysis systems,
peritoneal dialysis systems, neonatal ventilator incubators, ventilators for both adults and infants,
anaesthesia 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 cl ai m that units with this modification are certifi ed or l is te d as hospital-grade
by APC or any other organization. Therefore, these units do not meet the requirements for use in
direct patient care.
