Step 7 - Dual AC Power - Optional
A Dual AC power option provides the capability to connect to two separate AC feeds: a primary AC feed and a secondary
AC feed. The feeds can be direct from the power utility, or they can be a combination of utility feeds and UPS or generator
feeds. The preferred (primary) feed is determined by the user. In the event of failure of the primary feed, the system will
automatically transfer the load to the secondary feed without power interruption.
Dual AC is included as a standard feature in the:
GS1280 Model 32 with Dual AC (DA/DY-1280A-CC)
GS1280 Model 64 with Dual AC (DA/DY-1280A-BD)
Dual AC is an option for:
GS1280 Model 8
GS1280 Model 16
GS1280 Model 32 Single AC (DA/DY-1280A-AC)
GS1280 Model 64 Single AC (DA/DY-1280A-AD)
