Overcurrent Protection
AC overcurrent protection for the Utility Interconnect (Grid-tie) must be provided
by the installer as part of the PV100S installation.
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
Enclosure
The AC terminals in the Transformer Enclosure (
T6-X1, T6-X2,
and
T6-X3)
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
Enclosure
The AC terminals in the Main Inverter Enclosure (
TB4-A, TB4-B,
and
TB4-C)
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
Enclosure
The AC line terminals in the AC Interface Enclosure (
S1-2T1, S1-4T2,
and
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
Enclosure
The DC terminals in the DC Interface Enclosure (
TB3-1, TB3-2,
and
TB3-3)
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
.
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
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.
