Step 1
: Select the
appropriate cable
type and
specifications. A:
30~50 mm; B: 3~5
mm.
Step 2
: Pass the
wire through the
terminal.
Step 3
: According to
the mark, lock the
wire into the hole on
the terminal and
tighten it with the
Allen key.
Step 4
: Push
the terminal
forward until a
‘click’ sound is
heard.
Step 5:
Connect the connected
load terminal to the load port of
the inverter and push the
terminal forward until a ‘click’
sound is heard and the terminal
has been connected.

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
