Operation

10.2.1Startup Procedure

To start the UPS from a fully powered-down condition:

1.Open the external power switch.

2.Open the UPS door.

3.Connect the power supply cables.

4.Ensure the correct phase rotation.

5.Confirm that the address DIP switch of the main Liebert FlexPower assemblies are different from each other, and they are within 1 to 6. If they are the same, adjust them to create different Liebert FlexPower assembly addresses.

Table 29 Dip switch matrix

FlexPower Assembly Address

Flex Power		Swtich Number Left to Right
Assembly
Assembly	1		2	3	4	5
Address Top to Bottom	1		2	3	4	5

6	Down		Up	Up	Down	Down

5	Up		Down	Up	Down	Down

4	Down		Down	Up	Down	Down

3	Up		Up	Down	Down	Down

2	Down		Up	Down	Down	Down

1	Up		Down	Down	Down	Down

NOTE

For standardization, if the quantity of modules in system is less than 6, for example 45kVA system, Emerson recommends setting the address bits of the modules as 1, 2, 3 respectively.

6.Close the external input circuit breaker and connect input power.

The LCD activates. The rectifier indicator flashes while the rectifier is starting. The rectifier enters normal operation state, and after about 30 seconds, the rectifier indicator stops blinking and is illuminated in a steady green. After initialization, the bypass static switch turns on. The mimic LEDs appear as shown Table 30.

LED	Status

Rectifier Indicator	Green
Battery Indicator	Red
Bypass Indicator	Green
Inverter Indicator	Off
Load Indicator	Green
Status Indicator	Amber

7.Ensure that the Liebert FlexPower assembly ready switches are latched (in Down position).

8.Close the external output circuit breaker.

9.Press the INVERTER ON button for 2 seconds. The inverter indicator flashes while the inverter is starting. After the inverter is ready, the UPS transfers from bypass to inverter, the bypass indicator turns Off, and the inverter indicator turns On. The UPS is in Normal Mode. The mimic LEDs will appear as shown below.
