A proper understanding and use of this operating and maintenance manual will
enhance UPS system reliability. Therefore, the manual should be given equal status
with the tools and equipment used to align and maintain the system. Conversely,
improper understanding or application of the principles set forth can result in impaired
system operation, loss of power to critical equipment loads, injury to personnel and/or
damage to the UPS.
The following guidelines will assist in the understanding and use of this manual.
1.
Become familiar with the Table of Contents. It is here that the user can
first determine where in the manual required information or guidance can be
found.
2.
Read through the entire manual so as to become familiar with its style and
general contents.
3.
Know the manual’s limitations. It is not the intent of this manual to give a
detailed theory of operation of the UPS system. Troubleshooting is limited to the
isolation and correction of problems that are signaled by the Control!
Monitoring/Alarm Panel.
4.
Be thoroughly familiar with the safety precautions outlined in Sections II
and IV of the manual.
5.
Do not take short cuts when operating the UPS or performing mainte-
nance on the system. A slower, more deliberate pace will give better results
because it eliminates confusion and any false conclusions which may be reached
by skipping steps. Careful adherence to step sequences presented herein is, more
often than not, the fastest way to achieve desired results.
6.
This manual is written based on the assumption that maintenance
personnel will be fully knowledgeable in electronics and aware of the hazards of
working with high voltage equipment.
Always remember that voltages may be
present even when the system has been fully shut down.
Use a voltmeter to check
terminals to ground.
There is no substitute for common sense.
7.
Don’t guess! If you don’t know, ask someone who does.
