4.4.3 UPS Setup Menu
The UPS Setup menu is used to set-up various UPS operating parameters and functions. This menu can be
password protected to prevent unauthorised access – see
’Operator Panel sub-menu’ on page 4-10.

Frequency: This can be set to a nominal value (i.e. 50Hz or 60Hz) or it can be configured as AUTO whereby
the UPS output frequency synchronises to the input mains frequency and changes to the nominal value (50/
60Hz) if the input mains supply fails.
N+x Redundancy: Where a system is designed to incorporate a number of redundant power modules, the
UPS contains more power modules than is required to power the full connected load. Therefore the system
could lose one (or more) power module before its ability to provide full load power is affected.
The
N+x Redundancy
setting determines the number of modules that can be inoperative before the system
sounds the
OUT OF REDUNDANCY
alarm. A practical example is shown in the table below:
Input sub-menu
PLL Enable: If enabled, the UPS synchronises the output frequency to the input frequency. If disabled, the
UPS output frequency is not synchronised, the Green status led flashes and the ‘automatic bypass’ facility is
inhibited which means that the load is not fully protected in the event of a UPS fault or overload condition.
Extended PLL Range: When enabled, the UPS output frequency synchronisation range is ±14% of the
nominal input frequency. When disabled this is reduced to ±2%.
