CAUTION: Fire Hazard
Before energizing, confirm that all hardware
is installed as shown on the Installation page.
Stacking battery terminal hardware in any
other order can overheat the terminals.

Procedures
WARNING: Lethal Voltage
Review the system configuration to identify all possible sources of
energy. Ensure ALL sources of power are disconnected before
performing any installation or maintenance on this equipment.
Confirm that the terminals are de-energized using a validated
voltmeter (rated for a minimum 1000 Vac and 1000 Vdc) to verify
the de-energized condition.
WARNING: Lethal Voltage
The numbered steps will remove power from the inverter and
charge controller. However, sources of energy may still be
present inside the wiring boxes and other locations. To ensure
absolute safety, disconnect ALL power connections at the source.
WARNING: Burn Hazard
Internal parts can become hot during operation. Do not remove
the cover during operation or touch any internal parts. Be sure to
allow them sufficient time to cool down before attempting to
perform any maintenance.
To de-energize or shut down the OutBack Power devices:
1. Open the AC circuit breakers.
2. Open the DC circuit breaker for the battery.
3. Open the PV circuit breaker, if present.
4. Open the ground-fault circuit breaker, if present.
5. Open the FLEXnet DC circuit breaker, if present.
6. Verify 0 Vdc on the DC input terminals of the inverter by placing the
voltmeter leads on and .
7. Verify 0 Vdc on the PV charge controller terminals, if present.
8. Verify less than 5 Vac on the AC output circuit terminals
and .
9. Verify less than 5 Vac on the AC input circuit terminals
and .

Pre-startup Procedures
After opening the AC and DC enclosures:
1. Double-check all wiring connections. Ensure all torque values are met.
See
Wiring Data
on the other side of this sheet.
2. Inspect any enclosures to ensure no tools or debris were left inside.
3. Disconnect all AC loads at the backup (or critical) load panel.
4. Disconnect the AC input to the inverter system at the source.
5. If a mechanical interlock is used, place it in the normal (non-bypass) position.
6. Using a digital voltmeter, verify 12, 24, or 48 Vdc at the battery source.
Confirm the polarity
.
These instructions assume the use of AC and DC wiring boxes of OutBack Power models.
To energize or start up the OutBack Power devices:
1. Close the DC circuit breaker from the battery bank to the inverter.
2. Using a digital voltmeter, verify 12, 24, or 48 Vdc on the DC input terminals by placing the
DVM leads on and . Confirm that the voltage and polarity are correct for the inverter
and charge controller models.
3. If PV is installed, verify the correct voltage and polarity at the charge controller terminals.
4. Close the ground-fault circuit breaker, if present.
5. Close the PV input circuit breakers, if present.
6. Close the circuit breaker for the FLEXnet DC, if present.
7. Using the system display, perform any necessary programming, particularly for the size of the
AC input source(s). See Sheet 3 for the Profile Wizard.
8. The factory default state for all FXR inverters is OFF. Using the system display, turn the
inverter to the ON state.
9. Using the DVM, verify the inverter AC output on the AC output circuit terminals and .
10. Without closing the inverter system’s AC input circuit breakers: Using the DVM, test the
voltage of any input AC source(s).
11. Connect the AC source. Close the inverter system’s AC input circuit breakers.
Using the DVM, verify 120 Vac on the AC input circuit terminals and .
NOTE
: After a brief delay, the inverter’s transfer relay will activate unless the inverter’s
settings have been changed. Using the system display, verify the input source and the
inverter’s charging function. After verification, disconnect the AC source.
12. Replace the covers on the AC and DC enclosures.
13. Close the AC output circuit breakers. Turn on the AC disconnects at the load panel
and test the inverter’s output while operating loads.
