Initial Turn On, Setpoints, and Adjustments

Shelf Turn On and Operational Checkout

Complete operational checkout prior to applying loads after initial installation of the plant, after the
addition of a shelf, and after maintenance requiring power-down. If a plant fault has been identified
refer to the Troubleshooting section.
NOTE: Proceed only after: the plant is installed, input power is available, outputs are tied to the AC
distribution panel or loads, and all other plant interface connections have been made.
CAUTION: Multi-Shelf Systems Only
Damage to inverters may occur if a shelf does not have a functioning System Controller or if an improper power-
up sequence is followed.
Never close a shelf CB1 when the shelf is DC powered unless there is a functioning System Controller in the shelf
and the shelf's inverters are indicating STANBY mode (amber LEDs ON).
Note: Complete steps 1-10 (setup all shelves) before closing CB1 on any shelf.
1. Ensure CB1 is OFF on all Distribution Disconnect Modules.
2. Check power wiring for errors. Measure inputs and outputs to GND for shorts.
3. Apply power to the DC inputs of all shelves.
4. All inverter STANDBY LEDs – ON. LEDs briefly cycle ON then OFF as the inverters initialize.
5. Verify that
i. System Controllers: INVERTER MAJOR LED - ON
ii. Distribution Monitors: OK LED - OFF
iii.Each Inverter: STANDBY LED - ON
6. Wait for System Update to complete. During this period the red FAIL LED on each inverter will flash until it is
communicating with the System Controller and the controller displays indicates:
7. Once all inverters are communicating with the System Controller the following screen will appear, provided
there are no alarm conditions (in place of the "X" will be the users actual voltage and current readings):
8. The current status of the system should be as follows:
i. System Controllers:
1. CONTROLLER LED – ON green
2. INVERTER MAJOR LED – ON red
ii. Inverters:
3. STANDBY LED – ON
9. For each shelf in turn, set the SHELF # setpoint to a unique number between 1 and 4. The shelf designated as
"1" becomes the primary shelf.
Refer to the Display Navigation and Push Buttons section and to Setpoints in the Display Menus
section.
