Electrical installation
Caution ! Risk of electric shock !
■
Make sure the AC breaker or switch installed between the
PV Inverter and the grid (AC Utility).
Note
：
Please use Ue: 690Vac / Ie:25A circuit breaker.
■
Make sure the DC breaker or switch installed between the
PV Inverter and the PV array.
Note
：
Please use Ue: 1000Vdc / Ie:25A circuit breaker.
■
When working on the PV inverter, disconnect the AC breaker or
switch and DC breaker or switch.
■
Make sure that the AC breaker or switch and DC breaker or
switch cannot be unintentionally closed during installation and
commissioning works.
The electrical connections for the PV inverter are shown in Figure 1.

Connecting to the grid (AC utility)
Caution:
Before connecting to Grid(AC utility),please install a separate
circuit breaker between inverter and Grid
To connect the AC power cable proceed as follows:
Step 1. Measure the grid’s (i.e., the utility’s) voltage and frequency. The voltage
and frequency of the inverter are set at the factory to match the utility in
the country where the product will be delivered.
Step 2 .Before wiring the PV inverter ensure that the main breaker in the primary
utility breaker box is switched OFF. Switch this breaker ON only after all
wiring is completed as instructed below.
Step 3 .Remove the screws that secure the wire terminal cover, and carefully
remove the cover. Alternatively, remove the connector as shown in
Figure 2.
