5.5. Frequency Converter Operation (cF50 – cF60)
This mode is used when the load is different operating frequency of the mains frequency. For
example; this mode must be chosen to supply the load which
requires 60Hz where the mains
frequency is 50Hz.
When the UPS is operated under CF50 or CF60 mode, the recommended load connected
shall be 75% of rated capacity if the input voltage is 176~280Vac and 50% of the rated
capacity if the input voltage is 160~280Vac
* It shows the UPS is operated in “CVCF 50Hz mode”.
* It shows the UPS is operated in “CVCF 60Hz mode”.
5.7. Manual Bypass Mode
This feature is useful while performing maintenance or service and shall only be executed by
authorized Technical Service Personnel.
Manual by-pass enables the user to isolate the electronic circuitry of the UPS from the mains and
the load without interrupting the load operation by connecting the loads directly to the bypass
utility
supply.
During Frequency Converter Operation, You must not switch Maintenance Bypass Circuit
Breaker (F4) to “I” position!
The adjustment of frequency converter settings should be done by authorized Technical
Personnel.
During Manual Bypass operation; in case of any mains interruption occurs, all loads on the
output will be deenergized. Manual Bypass Operation should not be preferred for long time
use.
