Energize/Startup
Procedures
To energize or start up the system:
1. Using a digital voltmeter (DVM), verify 12, 24, or 48 Vdc on the battery
terminals by placing the DVM leads on and . Confirm that the
voltage is correct for the inverter model. Confirm the polarity.
2. 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.
3. Connect the AC source. Verify 230 Vac on the AC input circuit breakers
by placing the DVM leads on and .
4. Replace the covers on the AC and DC enclosures.
5. Turn on (close) the GFDI circuit breaker.
6. Turn on (close) the PV input circuit breakers.
7. Turn on (close) the DC circuit breaker from the battery bank to the inverter.
8. Turn on (close) the FN-DC circuit breaker.
9. Check the system display or LED indicators. Ensure the inverter is in the
ON state. The factory default state for FXR inverters is OFF.
10. Turn on (close) the AC output and AC outlet circuit breakers.
11. If an electrical outlet has been installed, verify 230 Vac on the AC output
by placing the DVM leads in the slots of the outlet.
12. Turn on (close) the AC input circuit breakers.
13. Turn on the AC disconnects at the load panel and test the loads.

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.
5. Place the mechanical interlock in the normal (non-bypass) position.
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.

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.
