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.).
• 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
additional allowances for inverters arranged
above or below.
This minimizes heat dissipation from lower
inverters affecting operation of other inverters.

In order to connect the communication wiring to the inverter it is necessary to
replace the signal plug screw 20 with a 1/2” box connector (thread 14 NPSM) that
matches the wiring method chosen (e.g., conduit, exible conduit, etc.).
• Each cable connected to the communication
and control signals must pass through the
signal conduit 20 and signal wiring duct 17.
• RJ45 connectors a12 - RJ45 connectors
(A) and (B) available for the RS-485
communication are equivalent to each other and can be used interchangeably for input or output of the line to create a daisy chain connection
of the inverters.
• RS-485 connections a14 - If terminal blocks are used, signals RTN, +T/R and –T/R have to be cabled. Use a cable designed for use with
RS-485 communications such as Belden 3106A, which is a data cable wire with one twisted pair, one ground conductor, and a shield with
drain wire (equivalent). Locate mating connectors (provided in hardware bag) for the terminal block. Connect the three RS-485 leads (-RTN,
+T/R, -T/R) to the mating connector corresponding points. Attach the mating connector to line up with correct signals on either upper or lower
row of the terminal block.
• Daisy chain connection - Recommended length of total communication cable line for all inverters in the system is 1,000 meters (1094 yards)
or less. Depending on type of computer used, cable line
adaptor can be RS-485_RS232 or RS-485_USB.
• Termination switch A10 - On last inverter in a daisy
chain, or on a single inverter, activate termination
resistance of communication line by moving switch down
into ON position. All other inverters in daisy chain will
have the switch up in OFF position.
• Addressing each inverter - Default setting for RS-485
address is 2 and termination switch in OFF position.
When multiple inverters are connected in a daisy chain, it is
necessary to assign a different RS-485 address to each unit.
• The address can be changed before or after
commissioning using the display menu, see section 15.
Refer to the technical manual online for connections of signal
wiring a15.
The ±WT (WIND) terminals are not isolated and can
have hazardous voltages present. These terminals
must not be utilized for any purpose (for use with wind
models only).

• If there are two separate external disconnect switches (one for DC and the other for AC),
rst close the AC disconnect switch and then the DC disconnect switch. There is no order of priority for opening the disconnect switches.
• When the inverter has power, the rst check performed relates to input voltage:
If DC input voltage is lower than Vstart voltage (voltage required to begin the inverter’s grid connection) icon b14 remains off and the
“Waiting sun” message is displayed in area b10.
If DC input voltage is higher than Vstart voltage icon b14 is displayed and inverter goes to next stage . Voltage levels and input current
are displayed in the b15 and b16 elds.
• The inverter performs a control of grid parameters. Icon b22 represents grid distribution and can display the following states:
not present indicates AC voltage is absent, ashing indicates AC voltage is present but outside the parameters of the country of installation,
steady ON - indicates AC voltage is present and within the parameters of the country of installation; this status starts grid connection sequence.
• If the input voltage and the grid voltage are within the inverter operating intervals, connection to the grid will begin.
• Icon b21 represents an electrical plug that is connected when the inverter is connected to the grid and a disconnected when not connected.
When the connection sequence is complete, the inverter indicates its correct operation by making a sound and by the green LED coming on steady
on the LED panel. If the inverter signals any errors/warnings the messages and their codes will be indicated on the display.
