conditions, such as high temperature and ultraviolet radiation. Therefore, the
solar system and photovoltaic array must be connected by using a specialist
photovoltaic electric cable as the DC cable.
Caution!
Regarding the inverter equipped with DC switch, please ensure that the
switch is in "OFF" position before connecting the inverter with PV panels.
Then switch to "ON" when finishing connecting job.
Before connecting the PV panels, please ensure that the plug connectors
have the correct polarity. Incorrect polarity connection could permanently
damage the unit.
Check short-circuit current of the PV string. The total short-circuit current
of the PV string cannot exceed the inverter’s maximum DC current.
20
High voltage exists when the PV panel is exposed to the sun. Please secure
the terminal connection, and do NOT touch any exposed components in
case of electric shock.
If you choose the models without DC switch, an external disconnection
device should be used. It should be multi-pole switch-disconnector (all
poles disconnected simultaneously), which has been approved according
to standard IEC/EN 60947-3. The rated current should be between 20A
and 25A.
PV array should not be connected to the grounding conductor.
System designer or installer must meet the minimum array insulation
resistance to the ground when selecting the PV panel and designing the
system, based on the minimum value that the design of the PV functional
grounding in the inverter was based on. The minimum value of the total
resistance 33.3kΩ that the system must be met.
There is a risk of shock hazard if the total minimum resistance
requirement is not met.
3.4.3 RS485 Communication
RS485 interface is used for multipoint communication. EzLogger can monitor
and communicate with 20 inverters at the same time. But the maximum
length of the cable should not exceed 800m. All the inverters which
communicate through one cable should use provided RS485 interface (a
piece of 10# cable is recommend to be connected for waterproofing without
RS485 cable connection). The typical inverter connection graph through
RS485 is shown below.

Note1: The model Z20I4KTL, Z20I5KTL and Z20I6KTL are only used in Australia
(PV voltage lower than 600V).
Note2: For equipment or circuits energized from the MAINS, four categories
are considered:
• Category IV applies to equipment permanently connected at the origin
of an installation (upstream of the main distribution board). Examples are
54
electricity meters, primary overcurrent protection equipment and other
equipment connected directly to outdoor open lines. Outdoor PCE connected
downstream of the main distribution board is not considered OV category IV.
• Category III applies to equipment permanently connected in fixed
installations (downstream of, and including, the main distribution board).
Examples are switchgear and other equipment in an industrial installation;
• Category II applies to equipment not permanently connected to the
fixed installation. Examples are appliances, portable tools and other plug-
connected equipment;
• Category I applies to equipment connected to a circuit where
measures have been taken to reduce transient overvoltages to a low level.
