3. Click Send Configuration
4. Verify that the Present Inverter Data has the unit set as the Configured
Slave unit.
Important:
If the inverter's date (not the workstation's!) is odd then the
Inverter is OPERATIONAL SLAVE until midnight; if the date is even, the
Inverter is OPERATIONAL MASTER until midnight.
CAUTION
The Master/Slave configuration will only be activated after power is cycled on
the unit.
Important:
Verify that the date is the same on both the GT100E #1 and
GT100E #2. This will allow the daily role reversal option to function correctly.
Refer to the GUI Help menu for complete configuration instructions.
