FREQ RANGE: 2%
NO LOAD : 1
Frequency tracking range: output converter frequency will follow the bypass frequency
within these limits before returning to its own internal frequency. Standard setting:
nominal ±2%. Can be changed into nominal ±4% or ±6%. See 5.4.4 Set-up Menu.
No-load shutdown: after a 10 minutes delay the UPS will shut down during utility
failure if the load is < 2%. It will restart after the utility returns or when the unit is
switched off and on again.
Default setting = 1 (active). For disabling this feature see 5.4.4.
