UPS5000-S-600 kVA
User Manual (Singapore, Three-phase, Three-wire)
Prerequisites
● Ensure that the load power is stable. If the system load power fluctuation is
● Check that the number of redundant power modules and racks are appropriate.
Context
When the load power is small and stable, you can shut down the inverters in some
power modules so that these power modules enter hibernation mode and other
power modules bear all the load power. This improves the system efficiency in the
case of small load power and increases the power module service life. The
hibernation function can be set on the WebUI.
Procedure
Step 1 On the WebUI, choose Monitoring > Param. Settings > System Settings and set
Paral. sys. hibernate to Enable.
Step 2 Set the Hibernated redundant modules.
Step 3 Set the Module cycle hibernation period to an integer ranging from 1 to 100.
The default value is 30.

greater than 30% of the rated capacity of a module (for example, the single-
phase load power fluctuation is greater than 5 kVA for a 50 kVA module) or
the load power fluctuation is greater than 10%, the UPS may enter and exit
from hibernation mode repeatedly.
If the number is insufficient, the UPS may not enter hibernation mode.
