Prior to this procedure, supply power to the critical load through the bypass line. Start-up each UPS module
according to the module start-up procedures. You can then transfer the load from bypass to the UPS system per
instructions on the SCC Load Transfer Procedures Screen.
Refer to 3.3.1 - Start-Up Procedure for more details.
NOTE
If the system was shut down in response to an “Emergency Off” signal (typically
because of a load fault), there may be alarm messages on the LCD screen that
describe system conditions before (or at the time of) the shutdown. Some or all of the
alarm conditions may have already been resolved. To clear these alarm messages,
make sure the critical load is on bypass power and turn off the control power (see
Figure 8 and Figure 9). Wait at least ten minutes for the control power circuitry to
completely de-energize. After ten minutes, turn control power back on and follow the
start-up procedures on the UPS and SCC screens.
