Energize/Startup
Procedures
Pre-startup Procedures:
After opening the AC and DC enclosures:
1.
Double-check all wiring connections.
2.
Inspect the enclosure to ensure no tools
or debris has been left inside.
3.
Disconnect AC loads at the load panel.
4.
Disconnect AC inputs at the source.
5.
Place the mechanical interlock in the
normal (non-bypass) position.

De-energize/Shutdown
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 controllers.
However, sources of energy may still be
present in the AC and DC wiring boxes. 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 the parts sufficient time to
cool down before attempting to perform
any maintenance.
To de-energize or shut down the OutBack devices:
1.
Turn
off
(open)
the
AC
circuit
breakers.
2.
Turn
off
(open)
the
DC
circuit
breakers
for
the
battery.
Wait
5
minutes
for
the
devices
to
internally
discharge
themselves.
3.
Turn
off
(open)
the
PV
circuit
breakers.
4.
Turn
off
(open)
the
GFDI
circuit
breaker.
5.
Verify
0
Vdc
on
the
DC
input
terminal
of
the
master
inverter
by
placing
the
voltmeter
leads
on
and
.
6.
Verify
0
Vdc
on
the
DC
input
terminal
of
the
slave
inverter
by
placing
the
voltmeter
leads
on
and
.
7.
Verify
0
Vdc
on
the
PV
terminals
of
one
charge
controller
by
placing
the
voltmeter
leads
on
and
.
8.
Verify
0
Vdc
on
the
PV
terminals
of
the
other
charge
controller
by
placing
the
voltmeter
leads
on
and
.
9.
Verify
0
Vac
on
the
AC
output
circuit
breakers
by
placing
the
voltmeter
leads
on
and
.

To energize or start up the OutBack devices:
1.
Using a digital voltmeter (DVM), verify 12, 24, or 48 Vdc on the DC input terminals by placing
the DVM leads on and . Confirm that the voltage is correct for the inverter and charge
controller models.
Confirm the polarity
.
2.
Verify that the PV output for each charge controller is in the correct range of open-circuit
voltage and confirm the polarity by:
a) placing the DVM leads on and , and
b) placing the DVM leads on and .
3.
Verify 230 Vac on the terminals of the AC source and connect the source.
4.
Verify 230 Vac on the AC Input TBB by placing the DVM leads on and .
7.
Turn on (close) the GFDI circuit breaker.
8.
Turn on (close) the PV input circuit breakers.
9.
Turn on (close) the DC circuit breakers from the battery bank to the inverter.
10. Check the system display or LED indicators. Ensure the inverter is in the ON state.
The factory default state for FXR inverters is OFF.
11. Turn on (close) the FN-DC circuit breaker.
12. Turn on (close) the AC output circuit breakers.
13. Verify 230 Vac on the AC Output TBB by placing the DVM leads on and .
NOTE
: Assumes correct stacking programming with the Configuration Wizard.
16. Replace the covers on the AC and DC enclosures.
17. Turn on (close) the AC input circuit breakers.
18. Turn on the AC disconnects at the load panel and test the loads.
