Outback Power Systems FLEXpower ONE Quick Start Guide - Manual (Page 3)

Energize/Startup
Procedures
Pre-startup Procedures:
1.
Double-check all wiring connections.
2. Inspect the enclosure to ensure no tools or debris has been left inside.
3. Disconnect all AC loads at the backup (or critical) load panel.
4. Disconnect the AC input feed to the FLEXpower ONE at the source.
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. Turn on (close) the GFDI circuit breaker.
3. Verify the voltage on the PV terminal is in the correct range of open-circuit
voltage by placing the DVM leads on and . Confirm the polarity.
4. Turn on (close) the PV input circuit breakers.
5. Turn on (close) the DC circuit breaker from the battery bank to the inverter.
6. Verify 120 Vac on the AC output circuit breakers by placing the DVM leads
on and .
7. Turn on (close) the AC output circuit breakers.
8. Connect the AC source. Verify 120 Vac on the AC input circuit breakers
by placing the DVM leads on and .
9. Turn on (close) the AC input circuit breakers.
10. Turn on the AC disconnects at the load panel and test the loads.

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 controller. However, sources of
energy may still be present inside the GSLC 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 devices:
1. Turn off (open) the AC circuit breakers.
2. Turn off (open) the DC circuit breaker for the battery.
3. Turn off (open) the PV circuit breaker.
4. Turn off (open) the GFDI circuit breaker.
5. *Verify 0 Vdc on the DC input terminals of the inverter by
placing the voltmeter leads on and .
6. *Verify 0 Vdc on the PV terminal by placing the voltmeter
leads on and .
7. *Verify 0 Vac on the AC output circuit breakers by placing
the voltmeter leads on and .
