Trouble-Shooting Guide
Fault Conditions
The SynQor UPS has no user-serviceable parts within it. If it has an internal malfunction only a
factory trained personnel should attempt to repair it.
There are, however, several external conditions that could cause the UPS to not operate as
desired. These external conditions can likely be corrected by the user.
The 16 LEDs on the front panel of the battery pack are the best and first place to look to determine
what might be wrong with the UPS. The table on the next several pages is therefore organized
by what these LEDs indicate, and for each indication there is a listing of what might possibly be
wrong.
The front panel battery pack LED array is shown below. The designations of the 16 LEDs in this
array are used in the following table.
