Operation > TRANSFER LOAD 

From this menu you can move the load from the inverter to the bypass voltage, or vice versa. 

7.3.2.1

 

OPERATION > TRANSFER LOAD > TRANSFER LOAD TO INVERTER 

Transfers the load from the bypass voltage to the inverter voltage. 

7.3.2.2

 

OPERATION > TRANSFER LOAD > TRANSFER LOAD TO BYPASS 

Transfers the load from the inverter voltage to the bypass voltage. 

 

7.3.3

 

Operation > BATTERY TEST 

Only one function under this menu; it executes a battery test. Once the battery test begins you have the 
option of aborting the test before it finishes. 

Operational parameters for the battery test can be found  
in section 

 

7.2.3.1 "Setup > Battery > BATTERY TEST PARAMETERS" on page 30.
