Visual Inspection of Mechanical Connections
To perform a visual inspection of the PV100S mechanical connections:
Visual Inspection of Electrical Connections
To perform a visual inspection of the PV100S electrical connections:
1. Ensure that the AC and DC Disconnect Switches, as well as any utility
interconnect circuit breakers or main disconnect switches, are opened.
❐
2. Ensure all anchor bolts and any required seismic bracing is properly
tightened and in place.
❐
3. Remove the wiring access panels and front covers from the AC
Interface/Transformer assembly and Main Inverter Inductor Enclosure.
❐
4. Remove the latches and open the doors of the Main Inverter Enclosure,
the AC and DC Interface Enclosures, and Communication Enclosure
and inspect.
❐
5. Verify all wire conduit fittings and connections are properly tightened.
❐
1. Ensure that the AC and DC disconnect switches, as well as any utility
interconnect circuit breakers or main disconnect switches, are opened.
❐
2. Ensure all conductors 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 AC power conductors terminated at TB4-A, TB4-B, TB4-C
within the Main Inverter Enclosure are terminated correctly and
properly sequenced.
❐
4. Verify the AC power conductors terminated at S1-2T1, S1-4T2, S1-6T3
within the AC Interface Enclosure are terminated correctly and properly
sequenced.
❐
5. Verify DC power conductors terminated at TB3-1, TB3-2, TB3-3 within
the DC Interface Enclosure are terminated correctly and properly
polarized.
