1- Introduction and safety

Environmental Conditions

Adverse environmental conditions can lead to a reduction in performance. The equipment should be installed outdoors, but only in environmental conditions indicated in this manual. Care must be taken to provide adequate ventilation if installed indoors.

Improper or Prohibited Use

The following actions are dangerous and not consistent with acceptable practice under the terms of the warranty:

• Installing the equipment in environments with ammable conditions.

• Using the equipment with safety devices not working or disabled.

• Using the equipment or parts of the equipment by connecting it to other machines or

equipment, unless otherwise expressed.

• Modifying areas that are operator-restricted and/or altering parts of the equipment in order to vary the performance or change its protection.

• Cleaning with corrosive products that may corrode parts of the equipment or with products that might generate electrostatic charges.

• Using or installing the equipment or parts of it without having read and correctly interpreted the contents of this manual.

• Blocking airow to the cooling ns (e.g., warming or drying rags) on the unit or accessory

parts is dangerous and could compromise the inverter operation.

Arc fault detection (AFD)

The 2011 National Electric Code (NEC) and 2013 Canadian Electric Code (CEC) includes the requirement that a photovoltaic system with a DC voltage greater than 80V, and which is on a building or whose DC conductors enter a building, be equipped with a listed device which can detect a series DC arc fault and interrupt the circuit. This functionality is commonly referred to as a DC Arc Fault Circuit Interruption. The 2014 NEC Arc Fault requirements are not limited to systems on or in buildings and apply to all PV systems with a DC voltage greater than 80V. See

690.11 of the National Electric Code for more information.

The DC arc fault detection (AFD) solution is based on Digital Signal Processor (DSP) technology. The AFD module has two independent channels, designed to accommodate the two independent MPPT channels associated with all ABB string inverters, and has two current sensors and associated circuitry to identify the presence of a series DC arc fault at the input of either inverter MPPT channel.

The DC AFD module performs a self-test every time the system is started and the inverter display shows the result, which can only be pass or fail. If the inverter fails, an error code will be displayed and the inverter will not connect to the grid. If it passes, the inverter connects and works normally.

If a DC arc fault is detected during normal operations, the inverter disconnects from the AC grid. The DC arc fault error is indicated on the inverter display screen, and lock out of inverter operation is initiated until the fault is manually reset.

When choosing the installation location and position, comply with the following conditions:

• Install on a wall or strong structure capable of bearing the weight.

• Install vertically with a maximum incline of +/- 5°. If the mounted inverter is tilted to an angle

greater than the maximum noted, heat dissipation can be inhibited, and may result in less than expected output power.

• Install in a safe place where all switch handles and controls remain easy to reach and meet height requirements of the applicable electrical code. Install at eye level so the display and status LEDs can be easily seen.

• Ensure sufcient working area in front of the inverter to allow easy access and compliance

with the minimum clearance requirements of NEC 110.34(A).

• When planning the installation, maintain clearance distances shown to allow normal control functions and easy maintenance operations.

2 - Installation

For multiple-inverter installations, position the inverters side-by-side, maintaining minimum clearances. If the space available does not allow the side-by-side arrangement, multiple inverters can be placed in the staggered arrangement shown; this minimizes heat dissipation from lower inverters affecting operation of other inverters.

Minimum clearances illustrated include width of inverter plus additional allowances for inverters arranged above or below.

Conduit entries for all versions are located on the bottom of the wiring box along with the DC disconnect switch handle 14. Conduit entries are illustrated below. The appropriate conduit connector must be used in order to maintain required spacing between wiring groups and preserve the integrity of the NEMA 4X environmental rating.

• A silkscreen printed label on the wiring box front cover 08 illustrates the ON/OFF positioning of the disconnect switch handle.

• In the OFF position (open and locked), the DC disconnect switch handle will be turned counter-clockwise in a position parallel to the inverter mounting surface as illustrated below.

• In the ON position, the DC disconnect switch handle must be pushed in and turned clockwise to a position perpendicular to the inverter mounting surface.

• The cover is only removable with the DC disconnect switch handle set to the OFF position.

• A padlock can be inserted in the slot on the switch handle when in the OFF position to prevent the disconnect

from being turned to the ON position.

WARNING! The DC switch (14) disconnects the photovoltaic array current from the inverter when the switch is in OFF position. It DOES NOT disconnect the AC from the grid.

3 - Mounting and wiring

The process of joining the inverter and wiring box together should be completed before the conduit is secured. When completely tightened the wiring box will move up to meet the inverter.

It is recommended to employ exible conduit methods to allow for easy removal of the inverter, if

ever required.

Installation method with flexible conduit

When installing exible conduit with the TRIO, provide enough conduit to allow for approximately

1-1½” of vertical movement between the inverter and wiring box. Prior to making the conductor connections in the wiring box, provide enough conductor to allow for the movement of the wiring

box in the nal stages.

• Using a level, position the bracket

01 level on the wall, using it as a drilling template.

• Using a 10mm drill bit, drill the required 10 holes A 70mm deep.

• Using the 10 (ten) 10mm diameter wall anchors, screw the bracket to the wall.

• When installing in seismic Zone 3 or higher, the ve center wall anchors must be xed into a

wood/steel wall stud or concrete/ masonry wall.

3 - Mounting and wiring

• Remove the front cover 08 from the wiring box.

• Install the wiring box 02 onto the bracket by inserting the heads of the rear screws into the slots in the bracket.

Note: it is not necessary to install the inverter 03 at this time.

• Unscrew the connector screws 07 and remove the wiring boxto-inverter cover 04 so that the connector can be reached between the wiring box and the inverter.

• Put the wiring box-to-inverter cover in the special pocket provided at the back of the wiring box.

• Locate the four bolts protruding from the rear of the inverter chassis; these are used as mounting studs and are inserted into the four associated slots on the mounting bracket.

• Lift the inverter using two people and orient it to the bracket so the four studs are just above their associated slots.

• Once aligned, lower the inverter unit into position, ensuring all four studs are seated in their respective bracket slots.

• For ease of lifting, the optional lifting kit is recommended (part # 3M2200HNDK0). The kit includes both handles and eye bolts which screw into the inverter heatsink.

3 - Mounting and wiring

Installation method with rigid conduit

If installing rigid conduit with the TRIO, mount the inverter as instructed above before making the rigid conduit connections. The inverter wiring box moves up in the installation procedure and the connection of rigid conduit would prevent this necessary movement if installed prior to mounting the inverter.

• Once the wiring box and inverter are connected, screw in the two connector screws 07 located inside the wiring box to fully lock and seal the connection.

• Using a 13mm socket wrench, nish tightening each of the two

connector screws 07 to at least

13.3-14.75 ft-lbs (18-20Nm) torque.

• After tightening the connector screws 07, nish tightening the clamp screw 05 at the bottom of the wiring box to 13.3 ft-lbs (18Nm) of torque.

• Anchor the connected wiring box and inverter to the lower end of the bracket by tightening the locking screw 27 located underneath the wiring box.

• Upon completion, replace the front cover of the wiring box 08 and torque screws to at least 21 in-lbs (2Nm) to ensure proper waterproof sealing.
