6.2.1 Procedures For Startup Into Normal Mode
Warning
1. These procedures result in mains voltage being applied to the UPS output terminals.
2. If any load equipment is connected to the UPS output terminals, check with the user that it is safe to apply power. If the load is
not ready to receive power, ensure that it is safely isolated from the UPS output terminals.
3. Do not start the UPS until the installation is completed and the system has been commissioned by authorized personnel.
Use the following procedures to turn on the UPS from a fully powered down condition. In a parallel system, perform
each step of the procedures in every UPS module before proceeding to the next step.
1. Close the external input switch to the UPS to feed the mains power to the UPS, and close the external BCB. In split
bypass configuration, it is required to close both input switches.
At this point, the LCD starts up. The rectifier indicator flashes in green color during rectifier startup. About 30s after
the rectifier enters normal operation, the rectifier indicator goes solid green. After system initialization, the bypass
STS is closed. The UPS indicator states are as listed in Table 6-1.

2. Press and hold the INVERTER ON button for 2s.
The inverter starts up, and the inverter indicator flashes in green color. After the inverter is ready, the UPS transfers
from bypass to inverter, the bypass indicator turns off, the inverter indicator and output indicator turn on.
The UPS is in normal mode, and the UPS indicator states are as listed in Table 6-2.

6.2.2 Procedures For Startup In Battery Mode (Startup Without A.C. Input Supply)
1. Verify that the battery is properly connected.
2. Press the battery start button (see Figure 6-4) on the front panel of any power module.
At this point, the LCD starts up, and the battery indicator starts flashing in green color. After the rectifier has operated
normally for 30s, the battery indicator stops flashing and becomes solid green.
