Description
Filter Capacitor Fuse Fault
Indicates one of the filter-capacitor fuses
failed in Stack 3.
Photovoltaic Ground Fault Detection and
Interruption (GFDI). 5 A FU3 cleared and/or
CB3 has tripped
Logic 3.3 V Power Fail
Main Communication board PIB 5 V power
supply failure
Main control board PIB ±15 V power supply
failure
Main control board PIB 24 V auxiliary power
supply failure
Pre-charge operation not completed within
30 seconds
PV Voltage must be >0 Vdc close DS1 DS2 DS3
PV-voltage relative to existing DC-Bus (stack)
voltage must be <20 Vdc to perform pre-charge
(close DS1-2-3).
Internal non-recoverable fault in main controller
(DSP uP) or the Control Board.
SF0: Reserved
SF1: Invalid State Fault
SF2: Reserved
SF3: Software Incompatible
SF4: NVRAM Fault
SF5: Reserved
Protected Cabinet Door Open
External Interlock Fault
(optional, for customer equipment / usage)

Resolution
Following these steps. if fault continues, contact Eaton service
Check the 400 A LC filter fuses in Stack 3 (continuity check)
■ F19 –FSW7 | F20 –FSW8 | F21 –FSW9
■ Circuits from CAUX2-J3-5 to TB11-10
Reference the GFDI troubleshooting section
Contact Eaton
Check for 5 V on the power supply PS9
■ COMMC board J1(+) to J1(-) shall be 5 Vdc
PS9 feed from TB4-4 (+24 V) from power-supply PS1-EMI-2-L1
■
PS9 feed from TB4-12 (Gnd) from power-supply PS1-EMI-2-N
■
1. Check for +15 V on the power supply PS2 (from TB4-1)
– TB3-1 to PIB-J20-1 shall be +15 Vdc (to TB3-5 / PIB-J20-2)
2. Check for -15 V on the power supply PS3 (from TB4-2)
– TB3-9 to PIB-J20 shall be –15 Vdc (to TB3-5 / PIB-J20-2)
Check for 24 V on the aux. power supply
■ PS4 (CAN)
■ TB4-3 (+24 V) from power-supply PS1-EMI-2-L1
■ TB4-11 (Gnd) from power-supply PS1-EMI-2-N
1. Verify PV voltage, allow DC-bus voltage to diminish
(bleed-down). Reset fault on HMI, then re-start the pre-charge,
closing disconnects within 30-seconds of the HMI "charging"
state icon-buttons illumination.
2. Check the DC disconnect / pre-charge aux-switch (ST) wiring.
1. Reset Fault on HMI operation menu
2. Disable Inverter completely), then cycle the control-power.
! Warning of AC Arc-flash if/when CB2 is cycled!
3. Contact Eaton
1. Close all cabinet doors
2. Check cabinet door switches
Four optional provisions allowing external-event or
equipment-interfaced critical faults. Loss of signal-voltage
(open-circuit) type of action.
External Fault 1 – TB9-1 – PIB J14-3 (+24 Vdc)
❑
External Fault 2 – TB9-2 – PIB J14-4 (+24 Vdc)
❑
External Fault 3 – TB9-4 – PIB J14-5 (+24 Vdc)
❑
External Fault 4 – TB9-5 – PIB J14-6 (+24 Vdc)
