•Close CB5 CB1, CB2, CB3 and CB5 are closed

Operating Instructions

After initialization, the bypass SCR closes. Because the output circuit breaker is still open, the UPS channels power through the Maintenance Bypass Supply line (CB3). The bypass indicator extinguishes, provided that the bypass is normal.

The opening display is shown in the figure at right. The UPS Mimic display indicators will be:

Indicator	State

Rectifier indicator	Green

Battery indicator	Red

Bypass indicator	Off

Inverter indicator	Off

Output indicator	Off

Status indicator	Off

HELP

•Close CB5 (CB1, CB2, CB3 and CB5 are closed).

•The Maintenance Bypass supply is now in parallel with the UPS Static Switch supply.

•Verify that the Bypass indicator is Green, then open CB3.

The UPS powers from static bypass instead of from maintenance bypass. The bypass and load indicators turn on. The design of the hardware and software ensures uninterrupted output.

3.Close external battery circuit breaker.

After the UPS detects that the battery is connected, the red battery indicator extinguishes moments after the battery charger starts operation.

The UPS Mimic display indicators will be

Indicator	State

Rectifier indicator	Green

Battery indicator	Off

Bypass indicator	Green

Inverter indicator	Off

Output indicator	Green

Status indicator	Amber

4.Press the INVERTER ON control button for 2 seconds.

The inverter will start and the inverter indicator will flash green. After the inverter is ready, the

UPS will transfer from bypass to inverter, the bypass indicator will turn off and the inverter and load indicators will turn on.

The UPS is operating normally. The UPS Mimic display indicators will:

Indicator	State
Rectifier indicator	Green

Battery indicator	Off

Bypass indicator	Off

Inverter indicator	Green

Output indicator	Green

Status indicator	Green
