AC Input

The AC input (shorepower) supply to the system must be a 120/240Vac split-
phase system that provides two line conductors (referred to as L1 and L2), a
neutral, and ground. Each PROsine requires a line, neutral, and ground run to
it, so 2-conductor-plus-ground cable is needed with a 30A max circuit breaker
installed in the line conductor. Typically these AC input cables originate in a
distribution panel, providing a main disconnect and the separate 30A circuit
breaker required for the AC input of each PROsine. That distribution panel,
referred to as the "source panel," also provides neutral and ground busses,
allowing for easy connection of the neutral and ground conductors in the
cables.

AC Output

The AC output of each inverter•charger requires a separate 2-conductor-plus-
ground cable (line, neutral, and ground) run from the inverter•charger to a
120/240Vac split-phase sub-panel for the loads. The sub-panel, referred to as
the "load panel," must be equipped with a double-pole circuit breaker rated
30A max, 240Vac for the two line conductors (L1 and L2), and neutral and
ground busses for the neutral and ground conductors from each unit. The load
panel then provides circuit breakers for the 120Vac and 240Vac branch circuits
powering the loads. Since the neutral-to-ground bonding is provided upstream
(by one of the inverter•chargers in Invert mode, and by the utility otherwise)
this load panel must not bond the neutral to ground. Most panels have a
removable screw that allows the neutral to be unbonded.

Battery Disconnect and Over-Current Protection Requirements

As with a single inverter•charger system, batteries must have a fuse and
disconnect or a DC-rated circuit breaker in the positive side, matched to the
cable size. The recommendations about wire sizes, over-current protection,
disconnection means, and other important details discussed in
"Installation"
on page 19
(whether a single bank or two banks are used).

Series Sync Connection

The SYNC connectors on the inverter•chargers are connected by a series sync
cable. If this cable becomes damaged or lost, you can replace it with standard
4-conductor telephone cable, but the length must be ten feet or less.
NOTE
The series sync cable is an option and is not supplied with the PROsine 2.0
Inverter•Charger. Contact Xantrex or your distributor for this part.
