terminals must use a crimp-on type ring terminal or compression-type lug.
The terminals are one bolt per pole. See Figure 3-14 on page 3–15 for the
location of these terminals.
5. The AC power conductor wiring interfacing with the AC terminals in the
Main Inverter Enclosure are located at TB4-A, TB4-B, and TB4- C. These
terminals are to be tightened to a torque value of 275 in-lbs (31.1 Nm) for
model PV100S-208 and model PV100S-480. The terminals will accept a
conductor size of 350 kcmil. See Figure 3-15 on page 3–16 for the location of
these terminals.
6. The AC power conductor wiring interfacing with the AC terminals in the
AC Interface Enclosure are located at S1-2T1, S1-4T2, and S1-6T3. These
terminals should be tightened to a torque value of 310 in-lbs (35.0 Nm) for
model PV100S-208 and to a torque value of 115 in-lbs (13.0 Nm) for model
PV100S-480. See Figure 3-16 on page 3–16 for the location of these
terminals and the cautionary note on page 3–17.
7. The AC neutral conductor from the utility is terminated in the AC Interface
Enclosure at the TB6-Neutral terminal. This terminal requires the use of a
crimp-on type ring terminal or compression-type lug and should be tightened
to a torque value of 228 in-lbs (25.7 Nm) for model PV100S-208 and model
PV100S-480. See Figure 3-18 on page 3–18 for the location of these
terminals.
8. The DC power conductor wiring interfacing with the DC terminals at TB3-1,
TB3-2, and TB3-3 are to be tightened to a torque value of 500 in-lbs
(56.5 Nm) for model PV100S-208 and model PV100S-480. These terminals
will accept a conductor size of 500 kcmil. 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. See Figure 3-
19 on page 3–19 for the location of these terminals.
9. This product is intended to be installed as part of a permanently grounded
electrical system per the National Electric Code ANSI/NFPA 70. A copper
ground rod must be installed within three feet of the PV100S enclosure. This
is the single point earth ground for the inverter system. The single point
ground for the system is to be made at the AC ground bus bar (TB2) in the AC
Interface Enclosure. This terminal requires the use of a crimp on type ring
terminal or compression-type lug and should be tightened to a torque value of
420 in-lbs (47.5 Nm) for model PV100S-208 and model PV100S-480.
10. The equipment grounds on the PV100S are marked with this symbol:
11. AC overcurrent protection for the utility interconnect (Grid-tie) must be
provided by the installers as part of the PV100S installation.
CAUTION: Fire Hazard
In accordance with the National Electrical Code, ANSI/NFPA 70, connect only to a circuit
provided with 400 amperes maximum branch circuit overcurrent protection for model
PV100S-208 and only to a circuit provided with 200 amperes maximum branch circuit
overcurrent protection for model PV100S-480.
