Connect the left and right power cables from transformer to
the studs in the rear side of electronic module. Connectors
have a tactile mechanical locking. Connect the AC power cable
to the rear side (bottom left) of electronic module.
Note: avoid that cables touch the transformers.
Connect the AC cables from grid to AC connector located at
bottom-right side of transformer module.
Put the left and right covers of transformer module. Connect
the earth cables and fix the covers to transformer module by
using the 2 supplied screws (it is only shown the left side - repeat
the process for left side).

from wires that link the panel with the inverter before
the installation. risk of electrocution.

Check that power supply cables from photovoltaic panels are
disconnected or not alive.
do not disconnect the cables from photovoltaic
panels, risk of electrocution exists.
Address the DC cables from panels to DC input cable glands of
combinator module.
Connect the negative cable to “PV Array Negative” terminal
strip.
Connect the positive cable to “PV Array Positive” terminal
strip.
Connect the photovoltaic panels to the wires of combinator
module.
Check the open circuit voltage of each circuit (positive cable
of each circuit has to be isolated from DC bus) with a digital
voltmeter. Check the voltage between each positive cable and
negative of terminal strip first. Voltage can be a little bit different
from the expected open circuit votlage due to the temperature
of the module and/or the sunlight. Nevertheless, if
panels are properly wired, each circuit should be at a few volts
from the other ones.
Leave DC switches in OFF position.

The following procedure describes the steps to connect the inverter
to the protection switchgear panel (interconnection point).
