Answer
Question: “How do I... ”
Check the condition of the
batteries?
The results of the most recent battery test are stored at menu 3 1 2 1. To run a test of
battery condition, go to menu 3 1 1 and press the
button. When the test is complete,
the results are again stored in the Battery Results parameter.
Change the battery
low-voltage alarm
threshold? (or any other
alarm or operating limit?)
This parameter requires a trained person, knowing the correct password, to perform.
Without the proper password, you are able to only view operating limits, not change
them. Only authorized personnel should change these limits. For information about
making this or other password-protected adjustments, contact your service
representative.
Apply power to the load if
the unit will not operate?
Turn the optional external bypass switch to either the SERVICE or the LINE position. In
these two positions, utility power flows directly to the load. In the SERVICE position, the
UPS does not receive utility power and may be worked on for maintenance purposes.
Turn the external bypass
switch?
If the bypass switch is a Make-Before-Break type, you must press the red button
beside the switch before turning the switch.
Set the UPS to turn on in
High Efficiency mode?
Go to menu 4 1. Select the system mode desired at power-on by pressing the
or
button. When the display shows Auto High Efficiency, press the
button.

Set the UPS to operate in
High Efficiency mode on
weekends?
The Powerware 9170
+
system will not change operating modes as a timed event. But, if
you wish to conserve energy, before leaving for the weekend, go to menu 4 1. Select
High Efficiency and press the
button. After the weekend, return to the Automatic
mode by going to menu 4 1 again, and selecting Auto followed by pressing the
button.
Change the level of system
redundancy?
To view or change the redundancy level, go to menu 4 2 5.
Change the batteries?
Each side-by-side pair of battery modules forms one series string on the battery bus.
See “Battery Replacement” on page 96 for the battery replacement procedure.
Add/delete one or more
strings of batteries?
Physically install or remove battery modules as described on page 68. Record capacity
of external battery strings (in all external battery cabinets) by going to menu 4 2 6.
Add/delete one or more
power modules?
Physically install or remove power modules as described on page 68. The system
operating software senses the number and location of all power modules in the
cabinet. If you want to change the number of redundant power modules, go to
menu 4 2 5 and change the level of system redundancy.
