Frequency And Phase Coordination; Ups - Outback Power Systems FXR2012E Operator's Manual

The utility may simply name a standard to be followed. It may be necessary to look up the requirements
for a local standard and program them accordingly.
STAGE 1 Voltage (basic settings)

Over Voltage Clearance Time (seconds)

Over Voltage Trip (AC Voltage)

Under Voltage Clearance Time (seconds)

Under Voltage Trip (AC Voltage)
STAGE 2 Voltage (if required by utility)

Over Voltage Clearance Time (seconds)

Over Voltage Trip (AC Voltage)

Under Voltage Clearance Time (seconds)

Under Voltage Trip (AC Voltage)
See the tables beginning on page 76 for the default settings and ranges.

Frequency and Phase Coordination

Several other inverter adjustments are located in the Grid Interface Protection menu. These sensitive
items can only be changed with installer-level access.

The FXR inverter's operating frequency can be selected to either 50 or 60 Hz using the Grid Interface
Protection menu. This setting changes the inverter's input acceptance parameters, as well as its output.
See page 28 for more information on the inverter's frequency.

The FXR inverter's stacking function includes the option called Multi-Phase Coordination. The selectable
menu item is Coordinated AC Connect/Disconnect. The default setting is No. If selected to Yes, the AC
source is required to deliver appropriate input to all inverters in a stacked system. If the master or subphase
master inverters do not sense an acceptable AC source, the entire system disconnects from the source.
None of the inverters will reconnect until the source is acceptable for the duration of the appropriate timer.

If the inverter is in Grid Tied mode, the Re-Connect Delay timer is used.

If the inverter is any other AC input mode, the Connect Delay timer is used.
See pages 29 and 31 for more information on input acceptance and the transfer function.
See page 43 for more information on the stacking function and subphase master inverters.
See the tables beginning on page 76 for the default settings and ranges.
Failure

UPS

In UPS mode, the FXR parameters have been optimized to reduce the response time. If the utility grid
becomes unstable or is interrupted, the inverter can transfer to inverting with the fastest possible
response time. This allows the system to support sensitive AC loads with minimal interruption.
BENEFITS :

Constant power is provided to the loads with virtually no drop in voltage or current.
NOTES :

Due to the need for the FXR inverter to react quickly to AC source fluctuations, it must remain fully active at
all times. The inverter requires a continuous consumption of 42 watts.

For this reason, the Search function does not operate in this mode. (See page 28.)

Frequency Trip

Over Frequency Clearance Time (seconds)

Over Frequency Trip (Hertz)

Under Frequency Clearance Time (seconds)

Under Frequency Trip (Hertz)
NOTE: The Frequency Trip settings are dependent on
the inverter's operating frequency, which must be set
correctly. See page 11.
