5. CONNECTING TO THE GRID
Step 0
: Select the
suitable cable type
and specifications.
Step 1
: Thread the
wire through the
terminal.
Step 2
: Align the wire
with the marking, insert
it into the hole on the
terminal and tighten it.
Step 3
: Push the
terminal forward
until a "click" is
heard.
Step 4:
Connect the attached load
terminal to the inverter's load port and
push the terminal forward until it clicks
into place.

Recommended specifications for
DC input cables
Insert the crimped positive and negative cables into the corresponding photovoltaic connectors.
1. Positive contact
2. Negative contact
Make sure that the DC parameters of the strings are acceptable according to the technical specifications given in the datasheet and in the
Azzurro ZCS configurator. In addition,
check that the polarities of the photovoltaic cables are correct
.
Before removing the positive and negative PV connectors, make
sure that the DC rotary circuit breaker is in the OFF position.
3. Positive connector
4. Negative connector
Prepare the positive and negative photovoltaic cables.
Use a MC4 wrench to disconnect the
photovoltaic connectors
