6.4 Frequency Conversion Setup

During frequency converter mode, the bypass output is disabled and the inverter output frequency is ﬁxed as the user’s

inverter frequency setting. The inverter output frequency will not synchronize with the input frequency, even if input frequency

is within +/-3 Hz of the inverter frequency setting. If there is an internal fault, the UPS will shut down directly without

transferring to Bypass Mode. While in frequency converter mode, the output load will be derated by 30%.

Note: Remove the load from the output before setting up frequency conversion. Do not attempt to change frequency with an attached load.

Frequency Conversion Setup for On-line Mode / Battery Mode

The frequency converter cannot be set under the on-line or battery modes. As a result, the LCD will display a warning message

when the user attempts to set this item.
