This chapter serves as a troubleshooting guide when problems occur with the UPS. Solutions

problems that occur both during and after startup.

Table 5-1 lists the possible alarms of the main module or electronics modules. When these

alarms occur, the LCD displays the number and type of alarms. An audible alarm may also

sound. For each alarm listed in the table, an explanation of the cause is provided, as well as a

recommended action to take to resolve the problem.

alarms are present, with the variable x indicating the number of alarms. The type of alarm is

displayed on the second line of the LCD. In Example 5-1, three alarms are present. The

Fan Failure alarm has occurred, as well as two other alarms. Use the arrow keys on the
