FLEXpower ONE System Safety
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.

instructions unless qualified to do so or as instructed to do so by OutBack 
Power Systems Technical Support personnel. 
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. 
WARNING: Fire Hazard
 In residential installations: check for multi-wire branch circuit wiring at the
location for the installation. A possible fire hazard can exist if 120 Vac only 
sources (such as inverters and generators) are wired incorrectly into 
120/240 Vac panels containing multi-wire branch circuits. Consult the local 
electric code for assistance.
