IMPORTANT SAFETY INSTRUCTIONS
Installation Guidelines
This manual contains important instructions for the OutBack FX series inverter/charger system with the software which allows classic (two FX’s in series), parallel and series/parallel stacking of two to ten FX’s for higher power and/or higher voltage systems.
1 All of the AC wiring to the AC terminals is to be torqued to 30 inch-pounds (equivalent to 2.5 foot-pounds or 3.4 Nm).
Wiring to these terminals must meet requirements of the National Electric Code (NEC). The terminals will accept up to 6AWG. Use copper conductors only with insulation rated for 75˚ C. See the AC WIRING CONNECTIONS section of this manual for more information.
2 Torque the DC connections to 60 inch-pounds (equivalent to 5 foot-pounds or 6.8 Nm). Cables to these terminals must use
a crimp on type ring terminal or compression type lug. Cable must meet the requirements of the National Electrical Code. Use of large gauge cables (2/0 or 4/0 AWG) or larger is advisable to reduce losses and ensure high performance of the FX. Cables of too small a gauge can result in poor performance and even damage the FX. Keep the cables together as much as possible and ensure that both cables pass through the same knockout and conduit fittings and to allow the inductive currents to cancel.
3 For equipment grounding hook up, see the system configuration sections in this manual. Non-mobile (“M”) FXs are intended to
be installed as part of a permanently grounded electrical system per the NEC. Mobile FXs include integral “Ground-switching” mechanisms. Please refer to the MOBILE FX INFORMATION section of this manual for proper grounding instructions.
4 AC overcurrent protection for all connections must be provided by others as part of the installation.
5 DC battery circuit overcurrent protection must be provided by others as part of the installation. OutBack offers 100, 175 and 250
amp DC breakers (part number OBDC-XXX) which can be used with the FX. For “Mobile” installations, OutBack includes a stud mounted fuse which can be connected directly to the positive DC terminal of the FX – it is available in 100, 175 and 250 amp sizes (part number SMF-XXX). The stud mounted fuses require a 10mm hole in the battery terminal lug. US lugs are typically 3/8” diameter. Light filing may be required to insure proper fit of the nut shoulder into the lug hole.
6 The equipment ground on the inverter is marked with this symbol:
7 This inverter has a single phase output. It is marked with this symbol:
8 This inverter puts out a sine wave waveform. It is marked with this symbol:
9 CAUTION: To reduce the risk of fire, connect only to a circuit provided with 60 amp maximum branch-circuit overcurrent
protection in accordance with the National Electrical Code, ANSI/NFPA 70.
10 WARNING: To reduce the risk of fire, do not connect a single FX to both hot legs of a 120/240 VAC AC load center having multi
wire (common neutral) branch circuits connected. Use two FX’s wired in a series configuration or the addition of an X-240 autotransformer if you are connecting to a 120/240 VAC multi wire system.
11 IMPORTANT: Always install the battery terminal covers, even in systems that include the DCC (DC Compartment Cover).

IMPORTANT SAFETY INSTRUCTIONS
General Precautions
1. Before using the FX, read all instructions and cautionary markings on (1) the FX, (2) the batteries and (3) all appropriate sections of this installation and operation manual.
2. CAUTION - To reduce risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium, gel cell or absorbed glass mat type rechargeable batteries. Other types of batteries may burst, causing personal injury and damage.
3. The FX is approved for indoor mounting only and can be mounted in any position.
4. Do not disassemble the FX. Refer servicing to a qualified service center when service or repair is required. Incorrect re-assembly may result in a risk of electric shock or fire.
5. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning. Turning off the FX may not reduce this risk. Solar modules may produce hazardous voltages when exposed to light - cover them with opaque material before servicing any connected equipment.
6. WARNING - WORKING IN THE VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL OPERATION. Provide ventilation to outdoors from the battery compartment. The battery enclosure should be designed to prevent accumulation and concentration of hydrogen gas in “pockets” at the top of the enclosure. Vent the battery compartment from the highest point. A sloped lid can also be used to direct the flow of hydrogen to the vent opening at the highest possible location.
7. NEVER charge a frozen battery.
8. No terminals or lugs are required for hook-up of the AC wiring. AC wiring must be copper wire and rated for 75°C or higher. Battery cables must be rated for 75°C or higher. Crimped and sealed copper ring terminal lugs with a 5/16” hole should be used
to connect the battery cables to the DC terminals of this FX. If using the stud mounted fuse, the positive lug must have a hole of at least 10mm. Soldered cable lugs are also acceptable.
9. Torque all AC wiring connections to 30 inch-pounds (equivalent to 2.5 foot-pounds or 3.4 Nm).
10. Torque the DC connections to 60 inch-pounds (equivalent to 5 foot-pounds or 6.8 Nm).
11. Be careful with tools to reduce the risk of dropping metal objects onto batteries. It may short-circuit the batteries or other electrical parts resulting in fire or explosion.
Additional Notices
1. For instructions on mounting, see the MOUNTING section of this manual.
2. For battery installation and maintenance: read the battery manufacturer's instructions prior to installation and operation.
3. All installations must comply with local and national electrical codes and standards.
4. GROUNDING INSTRUCTIONS – The FX should be connected to a grounded, permanent wiring system. For all installations, the negative battery conductor should be bonded to the grounding system at one (and only one) point in the system. All installations should comply with national and local codes and ordinances. Do not positive ground the FX !
Personal Precautions While Working with Batteries
1. Someone should be within range of your voice to come to your aid.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
3. Wear complete eye protection. Avoid touching eyes while working near batteries. Wash your hands with soap and warm water when done.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cool water for at least 15 minutes and get medical attention immediately.
5. Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries.
6. NEVER smoke or allow a spark or flame in vicinity of a battery or generator.
7. Be extra cautious to reduce the risk of dropping a metal tool onto batteries. It could short-circuit the batteries or other electrical parts that may result in fire or explosion.
8. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a battery. A battery can produce a short circuit current high enough to weld a ring or the like to metal, causing severe burns.
9. If a remote or automatic generator start system is used, disable the automatic starting circuit and/or disconnect the generator from its starting battery while servicing it to prevent starting while servicing.

ATTENTION: All “FX” inverter/chargers are ETL listed to UL 1741.
All “Mobile” FX inverter/chargers are ETL listed to UL 458. ETL is a Nationally Recognized Testing Laboratory (NRTL).
NOMINAL SYSTEM AC VOLTAGE:
This is the AC output voltage produced by an FX system. Each FX produces 120 VAC but multiple FXs can be configured in parallel, series or 3-phase to produce different voltages between their AC output connections.
Single Phase 120 VAC at 60 Hz (VAC = volts AC, Hz = hertz) Series Stacked 120 VAC at 60 Hz per AC output leg / 240VAC at 60Hz between the AC output legs Parallel Stacked 120 VAC at 60 Hz on one AC output leg Three Phase Stacked 120 VAC at 60 Hz per AC output leg / 208 VAC at 60 Hz between AC output legs (Y-connected)
RECOMMENDED DC VOLTAGE RANGE:
This is the DC battery voltage range to be used for operating the FX. The last two digits in the model number designate the nominal DC voltage. Example: FX2024MT – 24V DC Voltage. The recommended battery voltage range is as follows.
12V Systems 11 – 16 VDC (VDC = volts DC) 24V Systems 22 – 32 VDC 32V Systems 29 – 43 VDC 48V Systems 44 – 64 VDC
MAXIMUM DC INPUT CURRENT:
This is the maximum DC current that the FX will draw from the battery when starting very large AC loads. It is not used for sizing the DC disconnect or selecting DC cable gauge. It is used to select the minimum reasonable battery capacity.
12V FXs 600 ADC per FX (ADC = amps DC) 24V FXs 300 ADC per FX 32V FXs 225 ADC per FX 48V FXs 150 ADC per FX
RATED DC INPUT CURRENT:
This is the maximum continuous DC current that the FX will draw from the batteries when inverting. FX2012(M)T 190 ADC (ADC = amps DC) FX2524(M)T 120 ADC
FX2532(M)T 90 ADC FX3048T 70 ADC VFX2812(M) 265 ADC VFX3524(M) 170 ADC VFX3232(M) 115 ADC VFX3648 85 ADC
AC INPUT OPERATING VOLTAGE RANGE:
This is the recommended AC input voltage range to be supplied to the FX. Voltages outside of this range may damage AC
loads connected to the FXs AC output terminals. This is only a recommendation, neither the FX’s defaults nor the set point
limits.
All FXs 90 – 150 VAC (VAC = volts AC) Defaults = 108 – 140 VAC
RATINGS
MAXIMUM AC INPUT CURRENT:
An AC input source connected to the FX supplies power for two separate internal AC circuits – the AC transfer switch and the
battery charger. The AC transfer switch transfers the AC input power through the FX to the AC loads connected to the AC
output of the FX. The FX’s battery charger will “back off” when the combined amperage of the AC loads and the battery
charger exceeds the “AC Input Limit” (default of 28 AAC for Mobile FXs, 48 AAC for non-Moblie FXs). This “AC Input Limit”
can be adjusted so as not to overload a generator or trip a breaker that is connected to the AC input of the FX. If your
generator cannot continuously produce the “AC Input Limit” or you are connecting to an AC input source that has a breaker
that is rated for less than the “AC Input Limit”, please refer to the ADVANCED section to change this setting.
All “Mobile” FXs 30 AAC per FX (AAC = amps AC)
All Other FXs 60 AAC per FX (AAC = amps AC)

RATINGS
MAXIMUM CURRENT FOR BATTERY CHARGER:
The FX uses AC current from the AC input source to charge the battery. Due to heat constraints, the FX limits this amount of current. The maximum and default values for this setting are shown below. Please refer to the programming section to adjust this setting. The battery charger has an efficiency of about 90%. There are other factors like cable losses that may reduce this efficiency. The maximum DC current that can be produced is also shown below. These maximum DC currents can only be attained in the “Bulk” charging stage.
FX2012(M)T AC Max = 12 AAC (Default = 10 AAC) DC Max = 100 ADC FX2524(M)T AC Max = 14 AAC (Default = 12 AAC) DC Max = 55 ADC FX2532(M)T AC Max = 14 AAC (Default = 12 AAC) DC Max = 40 ADC FX3048T AC Max = 14 AAC (Default = 12 AAC) DC Max = 35 ADC VFX2812(M) AC Max = 16 AAC (Default = 14 AAC) DC Max = 125 ADC VFX3524(M) AC Max = 20 AAC (Default = 18 AAC) DC Max = 85 ADC VFX3232(M) AC Max = 20 AAC (Default = 18 AAC) DC Max = 60 ADC VFX3648 AC Max = 20 AAC (Default = 18 AAC) DC Max = 45 ADC
AC INPUT FREQUENCY RANGE:
This is the AC input source’s frequency range of which the FX will accept and stay connected. If the AC input source is out of this range, the FX will not connect or stay connected.
All FXs 56 - 64 Hz
MAXIMUM AC OUTPUT CURRENT:
This is the amount of AC “Surge” current that the FX will supply. This amount of surge can only be supplies for a split second. After this split second the FX lowers this surge limit. Depending on the size of the surge, the FX can be overloaded for a minimum time of 5 seconds to a maximum time of 30 minutes. When passing an AC source through the FX via the AC transfer switch, the maximum AC output fault current will be determined by the AC source.
All 12 VDC FXs 40 AAC per FX for 1 millisecond All Other FXs 50 AAC per FX for 1 millisecond
MAXIMUM CONTINUOUS OUTPUT POWER:
Each FX has a maximum continuous output power it can deliver. This maximum continuous output power is hidden in the model number of the FX. For instance, an FX2012MT has a maximum continuous output power of 2000VA (volt-amps). The last two numbers (12 in this case) can be changed to 0’s because they refer to the battery voltage.
FX2012(M)T 2000 VA (VA = volt-amps) FX2524(M)T 2500 VA FX2532(M)T 2500 VA FX3048T 3000 VA VFX2812(M) 2800 VA VFX3524(M) 3500 VA VFX3232(M) 3200 VA VFX3648 3600 VA
MAXIMUM OVERCURRENT PROTECTION AMPACITY:
This rating specifies the proper overcurrent protection ampacity. OBDC are panel mount circuit breakers. SMF are DC terminal mounted fuses and should always be used in conjuncture with a disconnect mechanism. FX’s used in home installations should use properly sized DC circuit breakers. An OBDC circuit breaker includes both overcurrent protection and disconnection capability. SMFs are used primarily for marine installations where only DC overcurrent protection is required. SMFs are included with all “Mobile” FXs.

MOUNTING
All FX’s can be mounted in any position. Better performance will be achieved if it is mounted in a location which allows for air to circulate around the exterior of the casting. Locating the FX in a cool location will ensure the highest efficiency and power capacity.
The following drawings provide the mounting and overall dimensions of the FX with the DCC, ACA and DCA attached. All VFXs come with the DCC and all FX “T”s come with the Turbo. The ACA and the DCA must be ordered separately. The first dimension is inches and the second value in parenthesis is the metric value in millimeters.
ACA
DCA
Depth out from Wall / Height up from Shelf: 11.87 inches (301 mm) / 12.87 INCHES (327mm) with Turbo installed
For installations where the FX may be exposed to water spray a sealed FX must be used. A sealed FX that may be exposed to water spray should be mounted either with the base down (shelf mounting) or with the AC wiring compartment facing down (wall mounting). This will minimize the entry of water into the AC wiring compartment. If mounted with the base down, water cannot be allowed to accumulate around the FX’s base. There is a drainage system on the base of the FX to dispel condensation. If submerged, water can enter this drain and cause failure.
The ACA can be used to connect the FX to the PS2AC, PS4AC or 2” conduit. The side of the ACA can be used to add an AC outlet and one or two of OutBack’s AC rated OBDC circuit breakers (up to 70 amps max). When these items are added to the FX, it should only be used in an area that is protected from rain.
The DCA can be used to connect the FX to the PS2DC, PS4DC or 2” conduit.

COMPLETE OUTBACK INTEGRATED SYSTEMS
Shown below are complete systems of OutBack FX’s for indoor installations. The system with four FX’s is shown mounted to the OutBack PS4MP (Power System 4 Mounting Plate where the “4” in refers to the maximum number of FX’s that will fit). The PS4MP comes with six 1x20mm thread forming screws for attaching FX’s and breaker boxes. The use of an external toothed star washer (provided) is required on one screw on each piece of equipment in order to bite through the powder coating and ensure grounding of all metal components. The system with two FX’s is shown mounted to the smaller PS2MP power system mounting plate.
The mounting plate will typically need to be bolted to the studs in a wall using at least four 1/4” or 5/16” lag bolts 2” long. In addition to the mounting plate, these installations are also shown with an OutBack PS4DC or PS2DC (DC breaker box), PS4AC or PS2AC (AC breaker box), DCAs (DC Conduit Adapter), DCCs (DC Compartment Cover), and ACAs (AC Compartment Adapter). When two or more FX’s are installed in close proximity such as in this installation, it may be useful to install one or more DC-12 Fan Kits inside the PS4DC or PS2DC (only one will fit) that will pressurize this enclosure – forcing air up through the DC Manifold and down over the external fins of the FXs. This will improve the battery charging performance by reducing the possibility of the FX’s limiting charging due to reaching their maximum allowed temperatures. The AUX output of the FX can be used to power the DC-12 Fan.
These components are designed to complete the installation to NEC code while offering flexibility for future expansion.

The AC terminal block is designed to accept up to 6 AWG (13.3mm2) wires. A typical installation will use THHN type wire. 6 AWG (13.3mm 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.

INDICATORS & CONTROL WIRING
The AC wiring compartment also encloses the following items; a 6-port terminal block, an RJ-11 jack, an RJ-45 jack, a set of three “Battery” LEDs and a set of three “Status” LEDs. The 6-port terminal block contains ports for Inverter & On/Off, AUX + & AUX –, and XCT + & XCT -. The RJ-11 “Battery Temp” jack accepts only OutBack’s “RTS” battery temperature sensor. Non-OutBack sensors may fit, but if their thermister value is not identical to the RTS’s, your battery bank could be destroyed. The RJ-45 “MATE/HUB” jack accepts the CAT-5 cable that is included with the MATE and the HUB. The “Battery” LEDs give a quick indication of the battery voltage. The “Status” LEDs give a quick indication of whether the FX is inverting, has AC input power, or if an Error has occurred.
The “Battery” LEDs operate at the following voltage levels:
Nominal Battery Voltage
LED Color 12 VDC 24 VDC 48 VDC
Green 12.5 or higher 25.0 or higher 50.0 or higher Yellow 11.5 to 12.5 23.0 to 25.0 46.0 to 50.0 Red 11.5 or lower 23.0 or lower 46.0 or lower
The “Status” LEDs operate under the following conditions:
LED Color
Green Solid GREEN Inverter ON Flashing GREEN Search Mode or Slave Power Save Mode Off Inverter OFF
Yellow Solid YELLOW AC Source is connected Flashing YELLOW AC Input Live – Waiting to connect to the FX Off No AC Input Present
Red Solid RED Error – An Error Message will be automatically displayed on the MATE Flashing RED Warning – A non-critical fault happened to the FX. The MATE can access this info.
INVERTER ON/OFF
The left two terminals of the 6-port terminal block marked INVERTER and ON/OFF can be used to control the inverter’s output. Connecting the two terminals through a switch will allow control of the inverter output if a MATE is not available. A small jumper wire is pre-installed into these two ports of the terminal block and must be removed in order to add the external switch. If the FX’s AC output is off, check that the jumper wire is present and well connected. An installed switch overrides the control provided by the OutBack MATE. If the switch is set to OFF, the MATE will not be able to turn ON the inverter. The switch cannot put the FX into Search mode.
LED Action LED Indicates
AUXILIARY OUTPUT (AUX + / AUX -)
The Auxiliary output system uses the AUX + and AUX – terminals and is able to be programmed through the MATE to do a variety of tasks. The default use for these terminals is to drive one 12-volt fan for external cooling. The power available at these terminals is 12 VDC at 1.0 amps (12 watts) maximum. These terminals should not be connected to any type of DC load which has a high inrush current requirement. The FX includes internal electronic overcurrent protection for this 12 VDC output circuit which auto resets if it is short circuited. No additional fuses are required. Use the OutBack FX Turbo Kit or DC12-FAN for cooling. For automatic or advanced generator start functions, the Auxiliary Output can drive a 12V automotive relay for the 2-wire starting circuitry of a generator. OutBack Power Systems does not support 3-wire start generators; however, a 3-wire to 2-wire conversion kit is available from other sources.
XCT + / XCT -
These terminals are not operational at this time.
BATTERY TEMP {REMOTE TEMPERATURE SENSOR (RTS)}
The OutBack FX has a 4 conductor “phone” RJ-11 modular jack located in the AC compartment for the connection of an optional external battery temperature sensor, the RTS (sold separately), that allows for automatic adjustment of the battery charging process based on the temperature of the battery. Battery manufacturers provide recommended charge voltages based on temperatures of 25˚C / 77˚F. With the RTS attached, the FX adjusts the battery voltage 0.03 volts per degree Celsius for every 12-volts of battery present. When a HUB is used, the RTS must be plugged into the Master FX which must be plugged into port 1 of the HUB. If this is the case, only one RTS is required for all devices plugged into the HUB. The RTS should be stuck to the side of a battery below the electrolyte level so it can measure the temperature of the batteries. The wire from the RTS can be folded and routed underneath the transparent gray plastic lexan cover of the AC wiring compartment to allow connection to the battery. There is a small indentation in the aluminum casting between the battery terminals to allow for the wire to pass without affecting the sealing of the covers. When running additional wires under the smoked lexan cover, it may be required to snip some lexan away to allow for wire routing. The lexan will not crack when cutting or filing. IMPORTANT: Do not connect a different brand of battery temp sensor. It may cause battery failure!!!
MATE / HUB
The 8 conductor “Ethernet” RJ-45 modular jack allows direct connection of a MATE system controller and display to the FX using standard CAT-5 type cabling. If multiple FX’s or a FX and a MX charge controller are both in the system, an OutBack HUB communication manager is connected to this RJ-45 jack for stacking of the FX’s and for efficient system performance. The HUB acts similarly to a computer hub to combine the communication signals of the devices together into a networked system. OutBack offers two different HUB products at this time. The HUB-4 accepts up to four OutBack products and one MATE. The HUB-10 connects up to ten OutBack products and one MATE. NOTE: Although the HUB has 2 ports for MATEs, only the 1
st
port is operational.

BATTERY - FX CABLING
DC BATTERY TERMINALS
The DC terminals are made from solid brass with a stainless steel threaded stud. The threads are M8 x 1.25. The black terminal is negative and the red terminal is positive. DO NOT PUT ANY WASHERS BETWEEN THE TERMINAL MOUNTING SURFACE AND
THE ACTUAL BATTERY CABLE LUG. Place the lug, washers and nut in the following order: Lug, Flat Washer, Lock Washer, Nut. TORQUE TO 60 INCH-POUNDS (5 FOOT POUNDS) MAXIMUM (6.77 NM). Mobile FXs come with a fuse for protection of the battery
cables connected to the FX. If used, the fuse must be mounted to the positive terminal (red). The hole of the battery cable lugs must be at least 10mm to properly fit the fuse. If using a 3/8” hole, file this down to produce a 10mm hole. Place the lug, fuse and fuse nut on the terminal in the following order: Fuse, Lug, Fuse Nut. TORQUE THE FUSE NUT TO 60 INCH-POUNDS (5 FOOT POUNDS) MAXIMUM (6.77 NM). Too much torque on the fuse nut will cause the fuse nut to shatter! This will put your installation on hold. It is recommended that a separate means of disconnecting the positive battery cable be included in systems that use fuses.
UL listed DC rated circuit breakers are available from OutBack Power Systems with amperages of 100, 175 and 250 amps DC. All of the OutBack DC breakers come with threaded studs out the back for connection to ring type terminal lugs. ALWAYS INSTALL BREAKERS OR FUSES WITHIN THE POSITIVE BATTERY CABLE.
OutBack also offers stud mounted fuses (SMF) for non-NEC code installations in 100, 175, and 250 amp sizes. These are the same fuses included with the Mobile FX.
The minimum recommended cable size varies with the DC voltage. VFX2812, VFX2812M, FX2012T, FX2012MT, VFX3524 and VFX3524M installations must use 4/0 AWG (120mm2) cable minimum. VFX3648, FX2524T, FX2524MT, and FX3048T installations can use 2/0 AWG (70mm2) cable as long as the distances are short (less than 10 feet / 3 meters per cable). If longer distances are required, increase the cable size to the next size as a minimum. Keep the cables together as much as possible for their entire length. Tying or taping the cables together is also advisable.
EQUIPMENT GROUND TERMINALS
A set-screw type box lug is provided near the DC terminals to allow the connection of an equipment grounding conductor for the metal chassis of the inverter. It is located behind the battery negative terminal on the top of the inverter casting. A green ground symbol marks the location. When mounting an FX to a PS2MP or PS4MP, a star washer located under one of the four screws that connect the FXs chassis to the mounting plate provides grounding of the FX to the mounting plate. Connection to the ground terminal is not required if the star washer is used to connect the FX to the mounting plate and the mounting plate is grounded.
BATTERY TERMINAL COVERS
The battery terminal covers simply snap on. They are a little brittle, so use some care. Use a flat bladed screw driver blade in the slots provided on the sides of the cover to pry the cap off. If the installation is exposed, DC conduit may be required. Connection of 2-inch conduit is possible when the DCA option is added to the FX. Always install the Battery Terminal Covers, even in systems that have an DCC or a Turbo included.

FX ACCESSORIES
ACA (AC CONDUIT ADAPTER)
This plastic box slips into grooves on the AC end of the FX. This adapter extends the AC wiring compartment to match the PS4AC or PS2AC. It also provides more room for wiring than is available when using the supplied AC conduit plate.
There is a 2-inch TSC cut-out on the plastic box to allow it to be used with the PS4AC or PS2AC disconnect enclosure or 2-inch conduit.
The ACA may also be used for mounting two breakers OBDC breakers (rated for AC) and/or an AC outlet through the knockouts provided.
DCA (DC CONDUIT ADAPTER)
The DCA allows the connection of 2-inch TSC conduit to the FX. It fits on the opposite end of the FX from the AC wiring compartment. The location of the 2­inch conduit opening matches the 2-inch knockouts provided in the PS4DC or PS2DC enclosure.
When installing an FX with a PS4DC or PS2DC disconnect enclosure, both the DCA and DCC (or Turbo) are required.
DCC (DC COMPARTMENT COVER)
The DCC covers the DC terminal area and allows a space which can be used to mount other components such as a DC current shunt. The DCC can be used with or without the DCA.
When installing an FX with a PS4DC or PS2DC disconnect enclosure, both the DCA and DCC (or Turbo) are required.
The DCC is provided with all VFX inverter/chargers.

TURBO KIT INFORMATION
The Turbo Kit is an addition that is either included or can be added to any sealed FX. Typically, the Turbo Kit adds 300-500 watts of power to a sealed FX. This extra power is included in the model number for sealed FXs that come with Turbos. If the sealed FX did not come with a Turbo and one is added, then the FX will be able to produce the extra 300-500 watts of power in addition to the power that the model number indicates. Do not use the Turbo with a vented VFX! It will actually reduce the output power of the VFX!
The Turbo is highly recommended in hot climates or for installations that can use a few hundred watts of extra power. In hot climates or when the FX is the primary charging device, the chances of the FX overheating are heightened. When the FX gets to its temperature limits, it will back off the charging process to avoid overheating (and a shutdown of the FX). The Turbo Kit solves this problem by directing air over the casting and its fins, thus causing better convection cooling of the FX.
The signal powering the Turbo Kit fan comes from the auxiliary output of the FX. The default setting of the auxiliary output is set to “CoolFan” which starts the Turbo Kit automatically when the FX starts heating up.
The instructions for adding a Turbo Kit are included with the Turbo Kit or the FX. If you are also automatically starting a generator using the auxiliary output, you can program the auxiliary output to “GenAlert” or use the Advanced Generator Start (AGS) system and parallel the generator start wires with the Turbo Kit wires. When the generator is running the Turbo Kit is also running. This solution works because the FX gets hottest when it is charging. If the paralleling of the generator and the Turbo Kit doesn’t work properly, adding a 470 uF (micro Farad) electrolytic capacitor (found at your local electronics shop) across the auxiliary output will solve this problem.

HUB COMMUNICATION MANAGER
The HUB communication manager allows the MATE to control and monitor a maximum of ten OutBack products. Currently the HUB comes in two types. The HUB-4 can connect up to four Outback products (FX’s and/or MX-60’s). The HUB-10 (shown below) can connect up to ten Outback products (FX’s and/or MX-60’s). The FX’s can be operated in a stacked or independent configuration. If the FX’s are to be stacked, the HUB must be part of the system. In a stacked configuration, the Master FX must be plugged into port #1 of the HUB. The Slave inverters must use the following ports (example: for 8 inverters and 2 MX-60’s, the Master must be plugged into Port 1, and the seven Slaves must be plugged into Ports 2-8. The MX-60’s can use Ports 9&10). Future OutBack products will also be compatible with the HUB. When using the HUB, the MATE must be plugged into the 1st MATE port of the HUB.
The HUB manages both the inter-FX communications and the MATE-FX communication.
When a HUB is used in conjuncture with the RTS, the RTS (Remote Temperature Sensor) must be plugged into the Master FX which must be plugged into port 1 of the HUB. If this is the case, only one RTS is required for all devices plugged into the HUB.
When two or more FX’s are stacked in a series or parallel configuration, the system automatically turns off any excess slave FX’s to save power and maximize conversion efficiency. This power save system is fully automatic and works with or without the MATE connected to the system. Some programming is required when more than two FXs are stacked together. See the STACKING INFORMATION section of this manual for more information.
Currently on 3-phase systems there is a limit of one FX per phase (totaling three FX’s). To convert the HUB into 3-phase mode, you must move the jumper on the HUB to the “3-PH” position. See the HUB instruction manual for details.
One MATE system controller and display can be connected to the HUB. Although there are two Mate ports on the HUB, only the 1st Mate port is currently operational. The MATE can be located up to 1000 feet (305 meters) from the HUB / system location. Cabling from the HUB to the MATE is completed using standard CAT-5 type ethernet cable with RJ45 modular 8 conductor jacks. This wiring is considered to be low voltage / limited energy circuitry. Refer to the MATE manual for more information on the MATE.
All cabling from the FX and MX60 communication ports to the HUB is made with CAT-5 type ethernet cabling. The maximum distance from the HUB-4 to the FX or MX-60 should be less than 10 feet. OutBack includes two 3-foot (1 meter) and two 6-foot (2 meter) long CAT-5 cables standard with the HUB-4. OutBack includes two 3-foot (1 meter) long and four 6-foot (2 meter) long CAT-5 cables standard with the HUB-10. Check with your OutBack dealer for additional cables.

FX SYSTEM CONFIGURATIONS
The FX System Configuration section shows diagrams of some typical system configurations using the FX. These diagrams are for non-Mobile FX installations only. Below these diagrams are notes for how to change each diagrams to accommodate a Mobile installation. There are diagrams for a single FX, two FX’s in series or series/parallel (see NOTE below), two FX’s in parallel,
four FX’s in series/parallel (see NOTE below), four FX’s in parallel, and a 3-phase system. The diagrams show the proper breakers and wiring for the AC side of the installations as well as connections to the HUB, MATE and X-240 (if applicable). Also included is information on the maximum continuous power of the systems and proper DC breaker sizes. This information is dependent on whether the FX’s are sealed or vented and on the system’s battery voltage.
NOTE: Stacking FX’s in series/parallel means that there are FX’s directly connected to two separate 120VAC output legs. These two 120VAC output legs produce 240VAC between them (the series portion). By connecting the X-240 autotransformer between the two 120VAC output legs, these legs are magnetically coupled (indirectly connected). This allows all of the FX’s to power either of the 120VAC output legs (the parallel portion). Series/parallel stacking requires the use of the X-240 autotransformer and must use “OutBack” stacking programming.
Single FX System
The following diagram illustrates a typical single FX installation. This diagram is for a non-Mobile FX installation only. Below this diagram are notes for how to change this diagram to accommodate a Mobile installation. All AC wiring must handle a capacity of
50 amps AC or more. For ‘Mobile’ FX’s, a 30A input breaker should be used due to the maximum AC input pass-through rating of the Mobile FX’s. A single FX system can continuously power 2-3.6KW of loads depending on which model is used. Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output. A MATE must be connected to adjust any parameters or to display any meters. Once the FX has been programmed using the MATE, the MATE can be disconnected. The programming will be saved within the FX’s non-volatile memory even if the FX is completely shut down.
NON-MOBILE FX NOTES: The AC OUTPUT NEUTRAL IS NOT BONDED TO THE CHASSIS OR THE GROUND TERMINAL of
the FX system. This connection is to be made by the installer either in the AC service entrance or within the AC load distribution panel of the electrical system. The AC input, AC output and DC terminals are isolated from the metal chassis of the FX. Proper grounding of these circuits and the chassis of the FX is the responsibility of the installer.
MOBILE FX NOTES: The AC input source to the FX (grid and/or generator) must have an internal neutral-ground connection. On
the above diagram the AC source’s neutral conductor must go directly to the FXs AC NEUTRAL IN terminal or to a separate neutral busbar that is isolated from the FX’s AC output neutral. The AC output of the FX must go to a separate AC output busbar that is isolated from the AC input neutral. A bypass mechanism must bypass the AC source’s hot and neutral wires. Proper grounding of the DC circuit and the chassis of the FX is the responsibility of the installer.

FX SYSTEM CONFIGURATION – SERIES OR SERIES/PARALLEL DUAL FX SYSTEM
Series or Series/Parallel Dual FX System
The following diagram illustrates a typical series FX installation using two FX’s. This diagram is for a non-Mobile FX installation only. Below this diagram are notes for how to change this diagram to accommodate a Mobile installation. The AC wiring from
the AC source and to the AC loads must handle 50 amps AC or more. All other AC wiring must handle a capacity of 50 amps AC or more. For a ‘Mobile’ FX system, 30A input breakers should be used due to the maximum AC input pass-through rating of the Mobile FX’s. This type of FX system can continuously power 4-7.2KW of loads depending on which model is used. Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output. A HUB and a MATE must be connected to stack these FX’s in series. The MATE must be connected to adjust any parameters or to display any meters. The slave FX must be programmed through the MATE as a ‘Classic Slave’ (series stacking, no X-240) or as ‘OB Slave L2’ (series/parallel stacking, X-240 included). Once the FX has been programmed using the MATE, the MATE can be disconnected. The programming will be saved within the FX’s non-volatile memory even if the FX is completely shut down.
NOTES: The X-240 autotransformer (located at the top-middle of the diagram) should never be used in a system that is programmed
for “Classic” stacking. If an X-240 is connected between two 120 VAC output legs, program the top FX as Master (1-2PH MASTER) and the lower FX as an OutBack L2 slave (OB SLAVE L2). If the X-240 is not included in the system program the top FX as Master (1­2PH MASTER) and the lower FX as an OutBack L2 slave (OB SLAVE L2). See the STACKING INFORMATION section of the manual for more info.
When the FX’s are connected in series for 120/240 VAC, the X-240 autotransformer can be connected to the AC output to allow both of the FX’s capacity to be available on either of the 120 VAC output circuits. This allows higher efficiency and better performance as heavy 120 VAC loads are powered by both of the FX’s. The X-240 autotransformer also allows the master to power loads on either of the 120 VAC output circuits with the slave off. This reduces the idle power consumption and improves the system efficiency.
NON-MOBILE FX NOTES: The AC OUTPUT NEUTRAL IS NOT BONDED TO THE CHASSIS OR THE GROUND TERMINAL of
the FX system. This connection is to be made by the installer either in the AC service entrance or within the AC load distribution panel of the electrical system. The AC input, AC output and DC terminals are isolated from the metal chassis of the FX. Proper grounding of these circuits and the chassis of the FX is the responsibility of the installer.
MOBILE FX NOTES: The AC input source to the FX (grid and/or generator) must have an internal neutral-ground connection. On
the above diagram the AC source’s neutral conductor must go directly to the FXs AC NEUTRAL IN terminal or to a separate neutral busbar that is isolated from the FX’s AC output neutral. The AC output of the FX must go to a separate AC output busbar that is isolated from the AC input neutral. A bypass mechanism must bypass the AC source’s hot and neutral wires. Proper grounding of the DC circuit and the chassis of the FX is the responsibility of the installer.

For a ‘Mobile’ FX system, 30A input breakers should be used due to the maximum AC input pass-through rating of the Mobile FX’s. This type of FX system can continuously power 4-7.2KW of loads depending on which model is used. Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output. A HUB and a MATE must be connected to stack these FX’s in parallel. The MATE must be connected to adjust any parameters or to display any meters. Once the FX has been programmed using the MATE, the MATE can be disconnected. The programming will be saved within the FX’s non­volatile memory even if the FX is completely shut down.
NOTES: Program the top FX as Master (1-2PH MASTER) and the lower FX as an OutBack L1 Slave (OB SLAVE L1). See the

Series/Parallel Quad FX System
The following diagram illustrates a typical series/parallel FX installation using four FX’s. This diagram is for a non-Mobile FX installation only. Below this diagram are notes for how to change this diagram to accommodate a Mobile installation. The AC
wiring from the AC source and to the AC loads must handle 120 amps AC or more. The AC wiring connected to the QUO 100A dual bypass breakers must handle 100 amps AC or more. All other AC wiring must handle a capacity of 50 amps AC or more. For a ‘Mobile’ FX system, 30A input breakers should be used due to the maximum AC input pass-through rating of the Mobile FX’s. This type of FX system can continuously power 8-14.4KW of loads depending on which model is used. Connecting more power than the continuous rating of the FX may cause breakers to trip or the FX to shut off its AC output. A HUB, MATE and X-240 must be connected to successfully stack these FX’s in series/parallel. The MATE must be connected to adjust any parameters or to display any meters. Once the FX’s have been programmed using the MATE, the MATE can be disconnected. The programming will be saved within the FX’s non-volatile memory even if the FX is completely shut down.
NOTES: Program the top FX as the Master (1-2PH MASTER), the first Slave as an Outback L1 slave (OB Slave L1), and the second
and third Slaves as OutBack L2 slaves (OB SLAVE L2). See the STACKING INFORMATION section of the manual for more info. In systems that include three or more FX’s and must be series stacked, an X-240 autotransformer must be used. When the FX’s are
connected in series for 120/240 VAC, the X-240 can be connected to the two AC output legs to allow all of the FX’s capacity to be available on either of the 120 VAC output circuits. This allows higher efficiency and better performance as heavy 120 VAC loads are powered by more of the FX’s. The X-240 also allows the master to power loads on either of the 120 VAC output circuits with the slave off. This reduces the idle power consumption and improves the system efficiency.
NON-MOBILE FX NOTES: The AC OUTPUT NEUTRAL IS NOT BONDED TO THE CHASSIS OR THE GROUND TERMINAL of
the FX system. This connection is to be made by the installer either in the AC service entrance or within the AC load distribution panel of the electrical system. The AC input, AC output and DC terminals are isolated from the metal chassis of the FX. Proper grounding of these circuits and the chassis of the FX is the responsibility of the installer.
MOBILE FX NOTES: The AC input source to the FX (grid and/or generator) must have an internal neutral-ground connection. On
the above diagram the AC source’s neutral conductor must go directly to the FXs AC NEUTRAL IN terminal or to a separate neutral busbar that is isolated from the FX’s AC output neutral. The AC output of the FX must go to a separate AC output busbar that is isolated from the AC input neutral. A bypass mechanism must bypass the AC source’s hot and neutral wires. Proper grounding of the DC circuit and the chassis of the FX is the responsibility of the installer.
