AC WIRING CONNECTIONS
The FX system and the other OutBack balance of system components are designed to make it easy to meet both local and National
Electrical Codes (NEC) installation requirements. If you are not familiar with the NEC, you should have the equipment installed by a
qualified renewable energy equipment electrician. Contact your dealer for information on qualified electricians. All wiring methods are
to be made in accordance with the National Electrical Code, ANSI/NFPA 70.
The FX includes an AC wiring compartment with both a removable cover and AC conduit plate. Depending on the type of installation,
the AC conduit plate may or may not be used.
The AC terminal block is designed to accept up to 6 AWG (13.3mm
2
) wires. A typical installation will use THHN type wire. 6 AWG
(13.3mm
2
) wire is required in order to handle the 60 amp capacity of the non-Mobile FX’s AC transfer switch. 10 AWG (5.3 mm
2
) wire
or larger is required in order to handle the 30 amp capacity of the Mobile FX’s AC transfer switch. All AC wiring connected to the AC
terminal block must be rated for at least 75˚ C. Torque all of the set screws on the AC terminal block to 30 inch-pounds (equivalent to
2.5 foot-pounds or 3.4 Nm).
For a non-Mobile FX the AC hot input and hot output conductors should be supplied through 60 amp maximum AC branch rated circuit
breakers. The AC hot input conductor should be connected to the AC HOT IN terminal and the AC HOT OUT terminal, respectively.
The AC neutral input and AC neutral output conductors may be connected to the AC NEUTRAL IN and AC NEUTRAL OUT terminals or
a common Neutral bus. The AC NEUTRAL OUT terminal is common with the AC NEUTRAL IN terminal within the non-Mobile FX and
only one AC neutral connection is required to be connected to the FX if a separate AC neutral bus is installed. The ground wires of the
AC input and the AC output may be connected to the two CHASSIS GROUND terminals or a common Ground bus. The two CHASSIS
GROUND terminals are common within the non-Mobile FX so only one of them needs to be connected if a common Ground bus is
installed in the system.
For a Mobile FX the AC hot input and hot output conductors should be supplied through 30 amp maximum AC branch rated circuit
breakers. The AC hot input conductor should be connected to the AC HOT IN terminal and the AC HOT OUT terminal, respectively.
The AC neutral input conductor must be connected to the Mobile FX’s AC NEUTRAL IN terminal. The AC neutral output conductor
must be connected to the Mobile FX’s AC NEUTRAL OUT terminal. These two neutral terminals are not always connected within the
Mobile FX and are necessary for the proper functioning and protection of the Mobile FX’s ground-switching system. Connect the
ground conductors of the AC input and AC output to the CHASSIS GROUND terminal of the Mobile FX. If there is only one Mobile FX
in the system, leave the copper bus (provided) installed between the CHASSIS GROUND and NEU/GROUND BOND terminals. If
there is more than one Mobile FX in the system, remove the copper bus from every SLAVE FX.
Many installations will use the AC-IOB input/output bypass breaker assembly mounted in the PS2AC or PS4AC. This bypass assembly
allows the user to completely bypass the FX system for servicing or replacement. In “Normal” mode, the FXs AC hot outputs are
connected through the AC-IOB’s output breakers to the load bank. In “Bypass” mode, the AC source (generator or grid) is connected
through the AC-IOB’s bypass breakers to the load bank. In addition to the AC-IOB input/output bypass assembly, each FX has a
separate AC input breaker. When in “Bypass” mode these AC input breakers should be turned off to ensure no AC power is connected
to the FXs. After the FX has been powered down through the DC breaker, it can then be removed for servicing or replacement without
loss of AC power to the AC loads of the system.
NOTE: Non-Mobile FXs need only bypass the AC input hot conductors. Mobile FXs need to bypass both the AC input hot and AC input
neutral conductors.
