5.3.2 Wiring PV Input
Check the connection cables of the PV modules for correct polarity and make sure that the maximum open
circuit voltage shall never exceed 50V.
1
The diagram drawing of DC side is shown as below, notice that the connectors are in pair (male
and female connectors).
Note: Please use 14-10AWG(2-6mm
2
) wires for the PV input connection.

Check the DC connectors for correct polarity and connect them onto the unit.

Hazardous voltage
Whenever a PV panel is exposed to sunlight, a shock hazard exists at the
output wires or exposed terminals. Cover the panel with an opaque
material before making PV input connection.
To reduce the risk of electric shock, avoid touching the live components
and treat the terminals carefully.
NEVER connect or disconnect the DC connectors under load.
Risk of damage to the unit.
If the voltage of the PV modules exceeds the maximum input voltage of
the unit, it can be destroyed by the overvoltage. This will void all warranty
claims. Do not connect strings to the unit that have an open-circuit voltage
greater than the maximum input voltage of the unit.
Please use the same brand male and female PV connectors. Under any
conditions the total circuit current should never exceed the Max. Current.
