Xantrex Technology PV100S-480 installation manual Overcurrent Protection, Conductor Termination

Wiring - General

Overcurrent Protection

AC overcurrent protection for the Utility Interconnect (Grid-tie) must be provided by the installer as part of the PV100S installation.

CAUTION: Equipment Damage

In accordance with the NEC, ANSI/NFPA 70 (Ninth Edition) the following branch-circuit overcurrent protection must be provided:

•400A maximum for PV100S-208

•200A maximum for PV100S-480

Conductor Termination

	The PV100S has terminals and bus bars for making all wiring connections
	required for the installation. All terminals used for making AC and DC
	connections require the use of copper conductors with an insulation rating of
	90 °C (or higher). For wire gauge, bolt size, and torque values for the AC
	terminals, see Table 3-1. For wire gauge, bolt size, and torque values for the DC
	terminals, see Table 3-2.
Transformer	The AC terminals in the Transformer Enclosure (T6-X1,T6-X2,and T6-X3)
Enclosure	require the use of crimp-on type ring terminals or compression lugs. The terminals
	are one bolt per pole.
	See Figure 3-14 on page 3–15 for the location of these terminals.
Main Inverter	The AC terminals in the Main Inverter Enclosure (TB4-A,TB4-B,and TB4-C)
Enclosure	have two openings per pole. These terminals do not require the use of crimp-on
	type ring terminals or compression lugs.
	See Figure 3-15 on page 3–16 for the location of these terminals.
AC Interface	The AC line terminals in the AC Interface Enclosure (S1-2T1,S1-4T2,and
Enclosure	S1-6T3)are one bolt per pole. These terminals require the use of crimp-on type
	ring terminals or compression lugs.
	See Figure 3-16 on page 3–16 for the location of these terminals.
	The AC neutral terminal in the AC Interface Enclosure (TB6) has one bolt per
	pole and requires the use of crimp-on type ring terminals or compression lugs.
	See Figure 3-18 on page 3–18 for the location of this terminal.
DC Interface	The DC terminals in the DC Interface Enclosure (TB3-1,TB3-2,and TB3-3)
Enclosure	have two openings per pole. These terminals do not require the use of crimp-on
	type ring terminals or compression lugs.
	See Figure 3-19 on page 3–19 for the location of these terminals.
	Important: Keep these cables together as much as possible, and ensure that all cables
	pass through the same knockout and conduit fittings, thus allowing any inductive currents
	to cancel.
