Visual Inspection of Mechanical Connections

Visual Inspection of Mechanical Connections

To perform a visual inspection of the PV100S mechanical 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.	❐

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 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.
