Visual Inspection, Isolation Transformer Wye/Wye
To perform a visual inspection of the Isolation Transformer Wye/Wye:
Corrective Action
Perform after initial inspection (if required):
1. Correct any necessary repairs pertaining to the previous inspection steps.
2. Replace the wiring access panels to the AC interface/transformer assembly
and Main Inverter Enclosure.
3. Replace the latches and close the doors of the Main Inverter Enclosure, the
AC and DC Interface Enclosures, and communication enclosure.
4. Ensure that the AC and DC Disconnect Switches, as well as any utility
interconnect circuit breaker or main disconnect circuit breaker, are left open.
1. Ensure that the AC and DC Disconnect Switches, as well as any utility
Interconnect circuit breakers or main disconnect switches, are open.
❐
2. Verify all conductor and wiring connections interfacing with the
PV100S are tightened to the correct torque value.
For specific torque values, see Table 3-1, “AC Terminal Wire Gauge,
Bolt Size, and Torque Values” on page 3–12 and Table 3-2, “DC
Terminal Wire Gauge, Bolt Size, and Torque Values” on page 3–12.
❐
3. Verify the AC power conductors terminated at T6-X1, T6-X2, T6-X3
within the Transformer Enclosure are terminated correctly and properly
sequenced.
❐
4. Ensure the neutral on the inverter side (T6-X0) is left floating. If the
inverter side neutral is tied to ground, the inverter will not function
properly. Also, ensure that the neutral is not bonded to the isolation
transformer frame.
