Conductor Termination
The Xantrex inverter 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). If conductors with insulation rated higher than 90 °C are used,
base the wire size on the requirements for 90 °C wire, to prevent excessive
heating of the busbars, terminals, and connected devices. For bolt size, and
torque values for the AC terminals, see Table A-5 on page A–5. For bolt size, and
torque values for the DC terminals, see Table A-6 on page A–5.
AC Wiring The AC output wiring connects to the AC terminals in the AC interface enclosure
(+H0) identified as L1, L2, L3. These terminals require the use of a crimp-on type
ring terminal or compression-type lug. Keep these cables together as much as
possible and ensure that all cables pass through the same knockout and conduit
fittings, allowing any inductive currents to cancel. The AC line terminals in the AC
interface enclosure (L1, L2, and L3) have three bolts per pole and accommodate
a maximum of two cables per bolt.
For torque values, see Table A-5 on page A–5. See Figure 3-6 on page 3–8 for
the location of these terminals.
The auxiliary AC input wiring connects to the control voltage terminals in the AC
interface enclosure identified as -X2:L1 and -X2:L2. The auxiliary AC input
terminals are one wire per terminal (-X2:L1, -X2:L2). These terminals require a
crimp-on ferrule properly sized for the wire.
For torque values, see Table A-5 on page A–5. See Figure 3-7 on page 3–10 for
the location of these terminals.
If a Xantrex UPS is used, remove the links on -X2 between terminals -X2:23 and
-X2:24 and between -X2:25 and -X2:26. Connect the output of the Xantrex UPS to
terminals -X2:24 (L) and -X2:26 (N) and the input of the Xantrex UPS to either
terminals -X2:23 (L) and -X2:25 (N), or an external 230 V/50 Hz supply capable of
providing more than 0.5 KVA. The input UPS control voltage are one wire per
terminal (-X2:24, -X2:26). These terminals require a crimp-on ferrule properly
sized for the wire.
See Figure 3-7 on page 3–10 for the location of these terminals.
DC Wiring The PV input wiring connects to the DC terminals located in the DC interface
enclosure (+H2). These terminals requires the use of a crimp-on type ring
terminal or compression-type lug. Keep these cables together as much as
possible and ensure that all cables pass through the same knockout and conduit
fittings, allowing any inductive currents to cancel. The DC terminals in the DC
interface enclosure (PV+ and PV-) have eight bolts per pole and a maximum of
one cable per bolt.
For torque values, see Table A-6 on page A–5. See Figure 3-9 on page 3–12 for
the location of these terminals.
