POWER MANAGEMENT

Use Power Management to program power to individual loads to turn OFF or ON at specific times or as a result of

specific events. Only Load Modules with Power Management circuitry respond to Power Management programming.

Power Management enables you to selectively turn programmable Load Modules (receptacles) off and on to conserve energy, extend battery time, or control network devices based on:

∙A programmed schedule

∙Events such as utility power failure, battery time left, utility restored, UPS on bypass, and others

∙Real time control (manual override), including rebooting the load

Other features include load labeling, programmable delay for each action, warning displays, and linking outputs so if one load module turns OFF (or ON) another one will also. A manual override is also available (force off, force on, or reboot).

Read these instructions entirely before programming UPS. After reading these instructions, decide on a program schedule. Make a chart of needed program steps. Include scheduled events (day and time) as well as conditions such as utility failure, battery time left, and utility restored.

Program entries must be made in pairs. Program an output to turn both OFF and back ON at certain times or events. This pairing concept provides program closure for each load. Example: An output programmed to turn OFF at utility failure must also be programmed to turn ON at utility restoration.

Getting Started

Access Power Management (option 5) from the main menu on the LCD display. The Power Management menu offers the following selections:

∙Programming

∙Review

∙Override

∙Load Labels

If your UPS has password protection, then all selections require a password with the exception of Review.

Press the enter key to make a selection. Use the right and left arrow keys to display the available selections when a programmable item is flashing. Press enter to store your selection and flash the next item.

When reviewing the program, use the right arrow to display the next program step.

To program (or review), a program step box appears:

01)Load #0,0,0,0 Nothing Selected

ACTION DELAY(S) Turn OFF load (00)

Power Management programs consist of four elements:

∙Which Load Module

∙What event triggers the Load Module

∙Whether the Load Module turns ON or OFF

∙The time delay between the event and the Load Module reaction

CAUTION: A program step becomes active as soon as it is entered. Therefore, program the scheduled ON action for each load before programming the OFF action. Otherwise, turn OFF critical loads.

To enter a program step (password may be required):

1.Select a Load Module

A.Press the enter key to flash the first load module selection. Press the right or left arrow key to review available selections (detailed below).

B.Press Enter key to store the first load modules selection and flash the second one. Make load selections as required for this program step. After making all load selections, the second line flashes.

2.Select an Event to Trigger the Load Module

When the ”event” (second line) flashes, press the right or left arrow key to review available selections (detailed below). If Day Time or Date Time is selected, those items will also need to be programmed. After making all load selections, the ACTION (fourth line) flashes.

3.Turn the Load Module ON or OFF

When the fourth line flashes, press the right or left arrow key to review available selections (Turn OFF load, Turn ON load, or Warning). After selecting the action, the DELAY (S) flashes.

4.Select a Time Delay

Select delay of S for seconds or M for minutes. If no delay is required, leave this selection as ”S”. When the two delay digits are flashing, use the right or left arrow to select 00 to 99.

Press Enter after this final selection to flash the entire program step block. Review all selections of this step with your chart. Press Enter to confirm step or escape to make a change. Make a change the same way as described above. The selections are available in the same sequence.

Press the right arrow to display the next program step. The step number (1, 2, 3, etc.) is automatically assigned. The last step always says Nothing Selected in the second line. This is the initial screen for programming the next step.
