OutBack Power GS4048A and GS8048A QuickStart Guide with GSLC
CAUTION: Equipment Damage
These procedures should be done by a qualified installer who is trained on programming inverter power systems. 
Failure to set accurate parameters for the system could potentially cause equipment damage. Damage caused by 
inaccurate programming is not covered by the limited warranty for the system.
IMPORTANT
Check the firmware revision of all OutBack devices before use. The Radian inverter and MATE3 system display may not 
communicate or operate correctly unless their firmware is above a specified revision number.
For models GS8048A and GS4048A, the firmware must be revision 001.005.xxx or higher.
The MATE3 must be revision 002.017.xxx or higher.

WARNING: Fire/Explosion Hazard
Do not place combustible or flammable materials within 12 feet (3.7 m) of 
the equipment. This unit employs mechanical relays and is not ignition-
protected. Fumes or spills from flammable materials could be ignited by sparks.
WARNING: Personal Injury
Use safe lifting techniques and standard safety equipment when working with 
this equipment.
IMPORTANT: 
Clearance and access requirements may vary by location. Maintaining a 36” 
(91.4 cm) clear space in front of the system for access is recommended. 
Consult local electric code to confirm clearance and access requirements 
for the specific location.
