102 Setting the Time and Date

The UPS stores the time, date, and year in parameters that you can program (see Section 300 for more about

parameters). These parameters must be programmed correctly so that the UPS can store accurate information in its

alarm and system logs. Whenever the UPS has been shut down, you should reset the time and date after you restart the

UPS. To set the time, date, and year parameters, follow the steps below.

Note: When the unit is in parameter mode, the functions of the front panel keys change. The label inside the front door

of the unit explains what the keys do when the UPS is in parameter mode. The label also shows a

“Programming Template” with different key names for parameter mode.

1. To enter the parameter mode, hold down the [CANCEL] and [RUNTIME] keys together. Release the keys when the

display changes to P-00 (for parameter 0).

2. Enter the user password (377) by following these steps:

a. Press [CANCEL]. The display should show 0 (the value of parameter 0).

b. Use the [%LOAD] key to change the display to 377. If you accidentally scroll past 377, use the [VOUT] key

to go back.

Note: If you hold down the [%LOAD] or the [VOUT] key, the display will scroll more quickly after a few

seconds.

from 1 p.m. to 11:59 p.m., add twelve to the hour. For example, 2:30 p.m. would be 14:30.
