Issue:
How to perform a total power off or complete shutdown of the Smart-UPS Modular Ultra.

Product Line:
APC Smart-UPS Modular Ultra 5-20kW

Environment:
UPS Models that begin with SRYL5K up to SRYL20K
All Serial Numbers

Cause:
Need to safely power off the UPS for maintenance, relocation, or other operational reasons.

Resolution:
The SYSTEM ENABLE switch controls the internal power for all the modules (intelligence, power, and battery). Setting the switch to STANDBY disables the power. Setting the switch to ON allows the modules to turn ON.

To completely power down the system:

1. Set SYSTEM ENABLE switch to STANDBY.
2. Set Mains/Branch circuit breaker to OFF.
3. Disconnect internal battery modules.
4. Disconnect external battery frames (if installed).
5. Disconnect maintenance bypass source (if provided).
