4.5 UPS Setup

Output

Input

Voltage

Frequency

N+x Redundancy

To set the UPS output frequency (Hz)

Nominal Value: to set a numerical value for the output

frequency (50 or 60)

If enabled, the UPS reads the frequency of the input

voltage and then synchronises the output to the same

value.

If disabled, the UPS uses the set Nominal Value.

N+x Redundancy

To set the number of redundant boards

(refer to NB: Redundancy Settings)

Range

If enabled, the UPS synchronises the output voltage with

the input for variations in frequency of +/-14%

the nominal value.

If disabled, the PLL is synchronised for variations in

frequency of +/-2%.

NB: Redundancy Settings

This function is used to manage the redundancy of the power modules. For example: a load requires N power modules; X power

modules must be added to achieve N+X redundancy.

If the load applied exceeds the power supplied by N modules during operation, the UPS will signal the lack of redundancy.
