How to take the Galaxy 5000 UPS from total power off to normal operation

Issue:
Transitioning the Galaxy 5000 UPS from total power off to normal on-line operation.
 
Product line:
Galaxy 5000, Galaxy 5500
 
Environment:
All models, all serial numbers
 
Cause:
For various reasons, the Galaxy 5000 may be in a totally off state.  This guide illustrates how to restore it to normal operation.
 
Note: This is not for commissioning a new UPS.  The commissioning of a new UPS must be performed by a Schneider Electric trained and qualified service representative.
 
Resolution:
How to restore the Galaxy 5000 UPS from total power off to normal operation.  This procedure is for a single UPS without an external bypass panel.
 
These instructions are in the owner’s manual which can be located at http://www.apc.com/salestools/MBPN-8YPFLA/MBPN-8YPFLA_R0_EN.pdf
 
Step 1: Set the input Q1 switch to On
Step 2: Wait until the end of the UPS initialization with PFC start-up.
Step 2: Push the Menu Button
Step 3: Scroll to “Maintenance”
Step 4: Choose “Start the UPS”
Step 5: Turn the Q4S Switch to On
Step 6: Turn the output switch Q5N to On
Step 7: Turn the maintenance bypass switch Q3BP to Off
Step 8: Set the battery circuit breaker(s) QF1 to the On Position.
Step 9: Press the Green “Inverter Start Button”
The Inverter Assumes the load, and the UPS is normal operation with the load protected.
 
Caution: Never remove any covers or panels.  There are no user serviceable parts inside.
