Connecting AC Output Wiring

To connect each inverter•charger to the load panel
1. Connect 2-conductor-plus-ground cable to the Line 1 PROsine
Inverter•Charger’s AC Output line and neutral conductors, and connect
the cable’s ground wire to one of the output ground screws on the
inverter•charger.
2. Run the 2-conductor-plus-ground cable to the load panel and connect:
• The Line 1 conductor to the panel’s Line 1 input breaker
• The neutral to the panel’s neutral bus
• The ground to the panel’s ground bus
3. Repeat steps 2 and 3, connecting the Line 2, neutral, and ground from the
Line 2 inverter•charger to the load panel’s Line 2 input breaker, neutral
bus, and ground bus.
Configuring the Inverter Output Neutral Bonding
Electrical codes require that you unbond the neutral-ground connection of one
of the inverter•chargers. Otherwise when the units are inverting, they will both
connect the neutral to safety ground through a relay. Installation codes
stipulate that the neutral be connected to safety ground in one—and only
one—location.

To unbond the neutral in one of the inverter•chargers
1. Select one inverter•charger in which to unbond the neutral.
Generally, it does not matter which inverter•charger you select, but your
system may dictate that one unit in particular be unbonded.
2. Locate and remove the neutral-ground bonding screw at the back of the
AC wiring compartment.
3. Install the screw in the extra hole (identified as the position in which the
neutral is NOT automatically bonded) so it is available for future use if
you change your system.
4. Tighten the screw so it will not back out over time.
5. Leave the other inverter•charger’s neutral-ground bonding screw in the
automatic bonding position.
