Table 3 Max. DC Voltage Limitation
Max.DC Voltage
600V
WARNING!
PV module voltage is very high which belongs to dangerous voltage
range, please comply with the electric safety rules when connecting.
WARNING!
Please do not make PV positive or negative ground!
NOTE!
Please follow the requirements of PV modules as below:
Same type; Same quantity; Identical alignment; Identical tilt.
In order to save cable and reduce the DC loss, we suggest installing
the inverter near PV modules.

DANGER!
Danger to life due to high voltages on DC conductors.
When exposed to sunlight,the PV array generates dangerous DC
voltage which is present in the DC conductors.Touching the DC
conductors can lead to lethal electric shocks.
Cover the PV modules.
Do not touch the DC conductors.
Below tools are needed before connection.
Strpping pliers
Wire crimper
Wire crimper recommended model :
H4TC0001
manufacturer:Amphenol
6.0 mm
12AWG
trip length
d) Crimp pin contact by using the wire crimper.
c) Insert striped wire into pin contact and ensure all conductor strand are
captured in the pin contact.
f) Insert the wire into plug forcibly, when a "click” is heard or felt the pin contact
assembly is seated correctly. Then tighten the cable nut.
pin contact
Crimp these parts
e) Separate the DC connector as two parts: the plug and the cable nut.
Then insert the wire with pin contact through the cable nut.
Wire crimper
plug
a) Turn off the DC switch, then Choose 12 AWG wire to connect the PV module.
b) Trip 7mm of insulation from the wire end by using the strpping pliers.

cable nut
g) Use a multimeter to measure whether the positive and negative
polarities are correct, and check whether this PV module is normal.
h) Remove the blue protective cover of the PV+&-interface at the
bottom of the inverter, and insert the completed PV terminals
according to the positive and negative correspondence.
I) Cover the remaining unused PV terminals with the original blue
cover
j) Keep the DC switch of the inverter off (if there is a DC switch)
