staggered arrangement.
• Minimum clearances for staggered arrangements include width of inverter plus additional allowances for inverters
arranged above or below.

3
Environmental checks - See Technical Data,Section 17, to check environmental
parameters.
• Maximum operational ambient air temperature must be considered when
choosing location. Installing the inverter where operating temperatures exceed
specifications will result in power derating. It is recommended the inverter be installed
within specified temperature range.
• Exposure to direct sunlight will increase operational temperature of inverter
and may cause output power limiting. It is recommended to use a sun shade to minimize
direct sunlight when ambient air temperature around unit exceeds 104°F/40°C.
• Due to acoustical noise (about 50dBA at 1 m) from inverter, do not install in
rooms where prolonged presence of people or animals is expected.
ATTENTION –AIf installed indoors, the inverter must be inaccessible to unqualified
persons.
5. Wall mounting
When mounting the TRIO, first secure mounting bracket to desired location and
then install wiring box followed by inverter unit. When completely tightened wiring
box will move up to meet inverter. It is recommended to employ flexible conduit
methods to allow for possibility of inverter removal.
• Using a level, position mounting bracket on wall and use as a drilling template.
• Drill required holes using a drill with 10mm bit.
• Attach bracket to wall with ten wall anchors, 10mm in diameter, found in mounting kit.
• When installed in seismic Zone 3 or higher, the five center wall anchors must be
fixed into a wood/steel wall stud or concrete/masonry wall.
• When installing flexible conduit, provide enough conduit to allow for approximately
1”-1½” of vertical movement between inverter and wiring box.
• Prior to making conductor connections in wiring box, provide enough conductor to
allow for movement of wiring box in final stages.
• Hook wiring box on bracket by inserting heads of rear screws in bracket slots.
• Remove wiring box front cover 08.
• Loosen connector screws 07 to remove coupling cover 04 and store in pocket at
left-rear of wiring box.
• Locate four bolts protruding from rear of inverter chassis; use as mounting studs
and insert into four associated slots on mounting bracket as shown at right.
• Lift inverter using two people and orient it to bracket so four studs are just above
their associated slots.
NOTE: For easier lifting and handling, an optional lifting kit is available containing
handles and eyebolts that can be attached to holes in side of inverter unit.
• Clamp screw 05 is accessed externally at bottom of wiring box and used to
physically secure wiring box to inverter chassis.
• Push screw 05 upwards until it mates with inverter chassis and thread initially
by hand.
• Using a 20mm socket, tighten clamp screw 05 to lift wiring box toward inverter
until mating connectors of wiring box and inverter chassis seat fully.
DO NOT COMPLETELY TIGHTEN AT THIS TIME.
• Once wiring box and inverter are connected via screw 05, push screws 07 upward
to mate with inverter and initially thread by hand.
• Use a 13mm socket wrench to tighten connector screws 07 to at least 13.3-14.75
ft-lbs (18-20Nm) torque.
• Finish tightening clamp screw 05 to a torque of 13.3 ft-lbs (18Nm).
• Secure bottom of wiring box to wall bracket by tightening machine screw
through bottom locking tab 31 and into bottom hole of mounting bracket.

14. Commissioning
The inverter commissioning procedure is as follows:
1. Turn the DC disconnect switch in the ON position. If there are two separate external disconnect switches (one for DC and the other for AC), first close
the AC disconnect switch and then the DC disconnect switch.
2. Once powered, icon b11 comes on to indicate that the voltage from the PV array has reached the Vstart threshold.
For input voltages lower than Vstart, icon b11 remains off, “Waiting Sun” is shown in display area b7 and voltage
and current are present (icons b12 and b13).
3. Assoonas“WaitingSun”conditionsaremet,theinvertershowstheAFDboardself-testrunning. Theresultsareshownindisplayareab7.
If a problem on the AFD board is detected, the self-test will result in an error. Refer to section 16 below.
4. If there are no irregularities, the grid connection sequence starts. Once all the checks are
completed, icon b19 comes on. During these checks, icon b19 is flashing.
5. Icon b14 flashes to indicate the start-up phase; at the same time icon b15 will come on.
6. Immediately following the grid connection will start. Icon b18 will be displayed in steps until the connection is complete. After the inverter is connected,
the icon b18 will stay “plugged in”.
If there is not sufficient sunlight to connect to the grid, the unit will repeat the procedure until all the parameters controlling connection to the grid (grid
voltage and frequency, confirmation of no ground fault) are within range. During this procedure, the green LED flashes ON and OFF.
15. Arc fault detection
For –A models only, the AFD performs a self-test when the system is started. The inverter display shows the results of the self-test in area b7.
• If the self-test results are OK, the inverter will continue to AC grid connection.
• If a potential problem on the AFD board is detected, the self-test will result in error E053.
Refer to the technical manual online for possible solutions to clear the error.
During normal operation the input current is continually measured and analyzed.
• If a DC arc fault is detected during operation, the inverter is disconnected from AC grid and error E050 will be shown on display.
• Press and hold the ESC key for three seconds to clear the E050 error which will start the self-test.
• If self-test results are OK, the inverter will reconnect to the AC grid; if the DC arc fault is still present, the self-test will result in error E053. Refer to the
technical manual online for solutions. The AFD self-test can be manually started anytime using the following procedure:
1. Turn off the inverter (switching off both DC and AC switches),
2. Turn on both the DC and AC switches and wait for display communication of the self-test result.
