Installation manual

❑ 5. In order for the UNITY/I to provide the desired output voltage(s), you must program the

Output Voltage Reference parameter (Parameter 05).

The Output Voltage Reference parameter programs the output voltage that the UPS will provide at

its output terminals. To program Parameter 05, follow the steps below.

a. Determine the proper Output Voltage Reference parameter setting for your application. See

Table 12.

Table 12: Output Voltage Reference Settings

b. Simultaneously hold down the [CANCEL] and [RUNTIME] keys on the unit’s front panel for

two seconds; release the keys when the four-digit display reads P-00.

c. Press [CANCEL]. The display should read 0.

d. Change the display reading to 377. Use the [%LOAD] key to increase the value and the

[VOUT] key to decrease the value.

e. Once the display reads 377, press [RUNTIME]. The display should read I.

f. Press [CANCEL]. The display should read P-00.

g. Press [%LOAD] until the display reads P-05. If you inadvertently step past P-05, press

[VOUT] to step back.

h. Once the display reads P-05, press [CANCEL]. If the number displayed is the correct output

voltage setting for your application (see Table 12), skip to step “k” below. If not, continue with

step “i.”

i. To change the output voltage setting, press [%LOAD] to increase the setting and [VOUT] to

decrease the setting.

j. Once the display shows the proper output voltage setting for your application, press [RUN-

TIME] to enter the new value. The new setting will remain on the display.

k. To escape parameter mode, press [VLINE] twice.

If you have wired the UPS
