Positive (+) Input Terminal and Die
Wiring on the DC side
1. Strip the DC cable insulation about 8 mm to expose the copper wire. Insert the cable
copper wire into the metal core of the connector and tighten it with a crimper (As
shown in the figure below).
2. Loosen the terminal cover and pass the cable through the terminal cover. Insert the
die into the wiring slot till you hear a sound indicating that the connection is in place.
Tighten the terminal cover (As shown in the figure below).
3. Check whether the PV array cable connection polarity is correct with a voltmeter
whose DC voltage measurement range is over 1000 V, and verify that the
open-circuit voltage does not exceed the specification. When the ambient
temperature is above 10°C, the open-circuit voltage of PV arrays can't exceed 90%
of the maximum DC voltage of the inverter. Otherwise, at the low temperatures, the
voltage of PV arrays may exceed the maximum input voltage of the inverter and
cause damage to the inverter.
4. Disconnect the circuit breaker on the DC side and connect the PV input cable to the
inverter separately.
