• Install on a wall or strong structure capable of bearing the weight.
in
• Install vertically with a maximum incline of +/- 5°.
• Maintain minimum clearance measurements shown.
• Choose a location that allows unobstructed airflow around the inverter.
• When possible, install at eye level so the display and status LEDs can be
6 in 6 in
easily seen.
• Ensure sufficient working area in front of the inverter to allow removal of the
wiring box cover and easy access for servicing the inverter.
• See technical data, section 16, to check the environmental parameters to be

observed (degree of protection, temperature, humidity, altitude, etc.).
in
• Select a well-ventilated location sheltered from direct sun radiation or any
other heat source (other inverters).
• Exposure to direct sunlight will increase operational temperature of the inverter and may cause output power limiting.
• It is recommended to use a sun shade to minimize direct sunlight when ambient air temperature around the unit exceeds 104°F/40°C.
• Position multiple inverters side-by-side, maintaining minimum clearances.
• Multiple inverters can also be placed in a staggered arrangement.
Minimum clearances illustrated for staggered
arrangement includes width of inverter plus
6" 6"
additional allowances for inverters arranged
above or below.
This minimizes heat dissipation from lower

For more details about product speci cations refer to the Instruction Manual
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesidered operation.
installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures: a) Reorient or relocate the receiving antenna;
b) Increase the separation between the equipment and receiver; c) Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected; d) Consult the dealer or an experienced radio/TV technician for help.

• Wiring methods used should be in accordance with the National Electric Code, ANSI/NFPA 70 (NEC), Canadian Electric Code (CEC), and/or
other local codes and regulations.
• The PV source conductors must be Listed PV wire per NEC 690.35.
• PV output conductors must consist of sheathed (jacketed) multi-conductor cables or installed in an approved raceway and must be isolated
from the enclosure and system grounding, as required by NEC 690.35 and is the responsibility of the installer.
• An external DC switch must be used if not integrated in the inverter; all -S models have an integrated DC switch.
• AC output overcurrent protection is not provided; it is the responsibility of the end user to provide protection for the AC output circuit.
• All photovoltaic source and output circuit conductors shall have disconnects complying with the NEC, Section 690, Part III.
• To reduce the risk of fire, connect only to a circuit provided with 15A maximum branch circuit overcurrent protection in accordance with the
NEC (ANSI/NFPA 70). See Maximum AC OCPD requirement in section 16 on next page.
• To prevent electrical hazards, all the connections must be carried out with the disconnect switch downstream of the inverter
(grid side) open and locked out.

The inverter cover is equipped with fixed hinges and is not intended
to be removed from the chassis.
• Wiring box cover 06 must be removed before opening the inverter cover 04.
• Loosen the four captive screws to remove the wiring box cover 06.
• Loosen the four captive screws on the inverter front cover 04.
Direct sunlight use caution
• Using light pressure, pull out and up on the cover so it rotates in an upward
arc to its rest position.
• Remove the protective film located on the inverter front cover display 01.
• When connections are complete, close covers and tighten the captive
screws with at least 2.0Nm (17.7in-lbs) torque to maintain waterproof
sealing.

The inverter uses pressure type terminal blocks for connection of all conductors.
• Acceptable wire size range is from 12 AWG to 6 AWG; refer to local codes for appropriate
27"
wire size; use only copper wire rated at least 90°C.
• To plug the input cables into the inverter it is necessary to replace the knockout plugs 18
and 19 with an EMT FITTING 3/4" (thread 14 NPSM).
All connection operations must be carried out with the DC disconnect switch
