EN
In addition to what is explained in this guide, the safety and installation
information provided in the techmical manual must be read and followed.
The technical documentation and the interface and management software for
the product are available at the website.
4.
Installation position -
• Install on a wall or strong structure capable of bearing weight.
• Install vertically with a maximum incline of +/- 5°.
• Maintain minimum clearance measurements shown.
• Ensure sufficient working area in front of inverter for wiring box access.
• Choose a location that allows unobstructed airflow around inverter.
• Position multiple inverters side-by-side, maintaining minimum clearances. Multiple
inverters can also be placed in staggered arrangement.
• Minimum clearances for staggered arrangements include width of inverter plus
additional allowances for inverters arranged above or below.
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.
Direct sunlight use caution
• 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.
Air ow restricted use caution
If installed indoors, the inverter must be
inaccessible to unqualified persons.
5.
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.
• If using rigid conduit, secure the conduit to the inverter using the knockouts.

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS-KEEP IN SAFE PLACE!
The labels on the TRIO inverter carry the markings, main technical data and identification of the equipment and manufacturer. The
technical data shown in this quick installation guide does not replace that shown on the labels attached to the equipment.
• PV source conductors must be Listed PV wire rated
1000V minimum per NEC 690.35.
• PV output conductors shall consist of sheathed
(jacketed) multi-conductor cables or be installed in an
approved raceway and must be isolated from enclosure
and system grounding, as required by NEC 690.35 and
is responsibility of the installer.
• The TRIO is designed without an isolation transformer
and intended to be installed per NFPA 70, 690.35 with
an ungrounded PV array and can be used only with PV
modules that do not require one of the terminals to be
grounded.
• All PV source and output circuit conductors must have disconnects complying with NEC, Section 690, Part III.
• To reduce risk of fire, connect only to circuit provided with 40A for 20kW and 50A for 27.6kW maximum branch circuit overcurrent protection in
accordance with NEC (ANSI/NFPA 70). See Maximum AC OCPD requirement in Technical Data table, Section 17.
• For models that do not include AC output overcurrent protection, the end user is responsible for providing protection for AC output circuit.
• Output circuits must be isolated from enclosure and system grounding, required by Articles 690.40 and 690.42 of NEC, ANSI/NFPA 70, and
are the responsibility of the installer.
This inverter has been factory programmed to automatically disconnect from the utility distribution system in compliance with UL 1741
and IEEE 1547 specifications. Default voltage and frequency trip limit and trip time settings to comply with these standards are shown
in table below. The Service menu can be used to adjust Voltage and Frequency Trip Limit and Trip Time Parameters according to Grid
requirements of installation locale. Refer to technical manual for instructions to use the Service menu.
