WARNING

Only qualified service personnel (such as a licensed electrician) should perform the UPS installation. Initial
startup must be performed by an authorized Eaton Customer Service Engineer. Risk of electrical shock.

Verify that UPS installation has been carried out correctly and the UPS ground has been connected.

NOTE

In a parallel capacity system (2+0 or 2+1), determine the minimum number of UPSs
required for capacity.

To start up the parallel system (Initial Startup or from complete System power off):

1.

Verify that all UPS breakers on the parallel tie cabinet are in the OFF position.

2.

Switch ON the utility power where the UPSs are connected.

3.

Wait for the front panel LCD to illuminate.

The

indicator flashes on each UPS.

4.

Verify fans have started.

5.

Switch all battery circuit breakers to the ON position.

The

indicator stops flashing on each UPS.

6.

Configure the UPS for parallel operation through the front panel:

•

Press any button on the front panel display to activate the menu options.

•

Using the

button, scroll to the Settings menu, and then press the

button twice to select the

User Settings menu.

•

Use the

button to scroll to the Parallel Operation Mode option and press the

button to enter

the menu.

•

Use the

button to scroll the desired option (either Redundant Mode or Capacity Mode).

•

Press the

button to save the setting.

7.

Press the

ESC

button until the Eaton

®

logo or Mimic screen appears.

8.

Repeat Steps 6 and 7 for the remaining UPSs in the parallel system.

9.

Shut down each UPS:

•

Switch the UPS battery circuit breaker to the OFF position.

The UPS is disconnected from the batteries and is on logic power only.

10. Cycle the utility power to the distribution point where the parallel tie cabinet and UPSs are connected. Wait

until the LCD is off before reapplying utility power.

11. Switch the UPS breakers on the parallel tie cabinet to the ON position.

12. Switch all battery circuit breakers to the ON position.
