Unit is equipped with DC brass battery terminals with 8M x 1.00 stainless steel threaded studs. Red terminal=battery positive Battery terminal covers Black terminal = battery negative SYSTEM PROTECTION Electrical systems are designed to protect you, the wires, the components, and the devices served by the system. Each FX must be part of a permanently grounded electrical system (see page 8). Grounding protects people and equipment from electrical shock. Grounding must be done according to local and national electrical codes. Circuit breakers — rated at 100% duty cycle — protect wiring by limiting the amount of current entering a system. All wired electrical systems require circuit breakers or fuses for protection. OutBack offers both breakers and fuses for over- current protection. If they are provided by other vendors, they must be properly rated.

Lexan cover protects AC Wiring Compartment Board AC WIRING COMPARTMENT BOARD •��AC HOT OUT supplies power to the loads. •��AC NEUTRAL OUT acts as neutral leg for loads supplied by the FX. •��CHASSIS GROUND connections are common and act as grounds for both the incoming and outgoing AC circuits. •��AC NEUTRAL IN acts as the neutral leg for AC power supplied by either the grid or a generator to the FX. •��AC HOT IN connects incoming AC from the grid or a generator to the FX. This AC is used to run loads and recharge batteries. Note: 13.3 mm2 (6 AWG) is the largest wire size the AC Wiring Compartment Board can accommodate. ���������� �������������� ����������������� ����������������� ������������� ��������� ������� ���� �� ��� ������ �������� ����� ����� ������������ �������� ��������������� �������� ������ ���� ���� ���� ���� AC Terminal Block--secures AC connections to the FX using set screws AC Wiring Board

1. Shut all AC breakers off or remove any fuses before connecting any wiring. 2. Shut off all DC breakers, including the PV breakers. 3. With all power off, run lengths of 10.0 mm2 (8 AWG) or larger wire between the AC Wiring Compartment Board AC OUT terminals and sufficient overcurrent protection via an AC circuit breaker. This breaker should be sized to protect the wire you are using, but should not exceed the maximum AC input current of the FX model used in the system (see FX product specifications, beginning on page 36). The breaker should be installed inside of a metal chassis such as OutBack’s FLEXware series or an existing panel. 4. With the over current protection connected, run lengths of 10.0 mm2 (8 AWG) wire between the AC Wiring Compartment Board AC IN terminals and the AC input breaker. The breaker should be installed inside of a metal chassis such as OutBack’s FLEXware series or an existing panel. The AC input hot conductor must be supplied through an AC branch-rated circuit breaker from your main electrical panel or source. This breaker should be sized to protect the wire you are using, but should not exceed the maximum AC input current of the FX model used in the system (see FX product specifications, beginning on page 36). WIRE CONNECTIONS Note: A system’s individual voltage requirements (230 VAC single phase or 3-phase), as well as how each FX is to function, all determine how the inverters are wired. Each FX must be wired to a specific leg�or�phase�of�the�system.��Each�FX�must�be�programmed�or�“stacked”�according�to�this�phase.��Please� see the STACKED FX SYSTEMS section, beginning on page 25, and the International Series GTFX and GVFX Grid-Interactive Inverter/Charger Programming Manual, before connecting any wires to or from the FX inverter.

•� Use�recommended�cable�sizes�(see�page�42)�to�reduce�losses�and�ensure�high�performance�of�FX� (smaller cables can reduce performance and possibly damage the unit). •� Keep�cables�together�(e.g.,�using�a�tie-wrap)�as�much�as�possible. •� Ensure�cables�pass�through�the�same�knockout�and�conduit�fittings.��This�helps�to�cancel�the�effects� of self-induction in the cables.

The�FX�inverter�can�be�used�singly,�or�in�a�“stacked”�system.��Stacking�refers�to�interfacing�multiple� inverters with the OutBack HUB networking accessory. Stacked inverters coordinate their outputs and can produce far more power than a single inverter. Wattage can be combined onto a single-phase bus, or onto a three-phase system. PARALLEL STACKING •�� FX inverters can be stacked in parallel. This will provide the wattage of multiple units on the same 230 Vac bus. •�� Up to ten FX inverters can be paralleled. Systems larger than four inverters require the OutBack HUB10 accessory. •���This�book�gives�examples�of�“parallel�dual”�and�“parallel�quad”�installations,�with�two�and�four�units� respectively. These systems require the use of the OutBack HUB4. The HUB10 can be used if other devices need to be networked along with the inverters. THREE-PHASE STACKING •�� Three FX inverters can be stacked to supply three-phase power. This will provide the wattage of three units on a 230/400 Vac bus. •�� Parallel stacking requires the use of the OutBack HUB4. The HUB10 can be used if other devices need to be networked along with the inverters.

During the warranty period beginning on the invoice date, OutBack Power Systems will repair or replace products covered under this limited warranty that are returned to OutBack Power Systems’ facility or to an OutBack Power Systems authorized repair facility, or that are repaired on site by an OutBack Power Systems authorized repair person. For full Warranty description, see previous page. Contacting OutBack To request warranty service, the customer must contact OutBack Technical Support at +1.360.618.4363, or [email protected]. To ensure warranty coverage, this contact must be within the effective warranty period. If service is required, the OutBack Technical Support representative will issue a Return Material Authorization (RMA) number. Troubleshooting In the event of a Product failure, the customer will need to work with an OutBack Technical Support representative to perform the necessary troubleshooting. This is a required step before a return can be performed. Internal troubleshooting requires a qualified technician to be present at the site of the Product, with a quality voltmeter that measures both DC and AC. The OutBack representative will request voltmeter readings, Product error messages, and other information. The vast majority of problems can be resolved on-site. If the customer does not provide these readings (or cannot visit the site), and the Product is found to have no problems upon return, OutBack may choose to charge additional labor and handling fees up to $180.00 USD. Return Material Authorization (RMA) A request for an RMA number requires all of the following information: 1. Product model and serial number; 2. Proof-of-purchase in the form of a copy of the original Product purchase invoice or receipt confirming the Product model number and serial number; 3. Description of the problem; and 4. Shipping address for the repaired or replacement equipment. Upon receiving this information, the OutBack representative can issue an RMA number.

After receiving the RMA number, the customer must pack the Product(s) authorized for return, along with a copy of the original purchase invoice and warranty certificate, in the original Product shipping container(s) or packaging providing equivalent or reasonable protection. The RMA number must be written on the outside of the packaging where it is clearly visible. The Product(s) must be shipped back to OutBack Power Systems in their original or equivalent packaging, to the following address: OutBack Power Systems RMA # ____________________ 6115 192nd Street NE Arlington, WA 98223 USA The customer must insure the shipment, or accept the risk of loss or damage during shipment. If a shipping box is needed for return of a Product, OutBack will, upon request, send a shipping box. IMPORTANT: OutBack is not responsible for shipping damage caused by improperly packaged Products, the repairs this damage might require, or the costs of these repairs. If, upon receipt of the Product, OutBack determines the Product or Product part is defective and that the defect is covered under the terms of this Warranty, OutBack will then, and only then, ship a repaired or replacement Product or Product part to the purchaser freight prepaid, non-expedited, using a carrier of OutBack’s choice, where applicable. If Product fails in ninety (90) or fewer days from original purchase date, OutBack will replace with a new Product. If Product fails after ninety (90) days and up to expiration of warranty, OutBack will, at its discretion, either repair and return a Product, or ship a replacement Product. OutBack will determine whether a Product is to be repaired or replaced in accordance with Product age and model. OutBack will authorize advance shipment of a replacement based on Product age and model. In cases where an OutBack dealer or distributor replaces a Product more than ninety (90) days old with a new Product, OutBack will NOT compensate that dealer or distributor with new stock unless the exchange was authorized in advance by OutBack. Out of Warranty If Product is out of warranty, OutBack will repair and return Product for a fee. Alternately, if applicable, upon request, OutBack will advance-ship replacement parts for a fee. If a shipping box is needed for return of out-of-warranty Product, OutBack will, upon request, send a shipping box. The customer is responsible for paying shipping to OutBack. The warranty period of any repaired or replacement Product or Product part is ninety (90) days from the date of shipment from OutBack, or the remainder of the initial warranty term, whichever is greater. This Warranty is void for any Product that has been modified by the customer without authorization by OutBack. A Product with a voided warranty will be treated the same as one with an expired warranty.
