*Neutral conductor shall be blue, line conductor shall be black or brown (preferred), protective earth bonding line shall be
yellow-green.
*Fix (moment: 0.6N.m) the connector of AC cable to the corresponding terminals
3.4.1 Connection to grid (AC side Connection)
3.4 Electrical Connection
(1) Check the grid voltage and frequency if it can comply with the required voltage and frequency of inverter connection.
(2) Add breaker or fuse to AC side, the specification should be more than 1.25 times of rated AC output current.
(3) The PE line of inverter should be connected to the earth, make sure the impedance of neutral wire and earth wire less than
10 ohm.
(4) Disconnect the breaker or fuse between the inverter and the utility.
(S) Connect the inverter to the grid as follows:
There are two AC connector brands for inverter, VACONN and WIELAND. Please refer to Figure 3.4.1-1
(6)The AC line construction shall be such that if the cord should slip in its anchorage, placing a strain on conductors, the
protective earthing conductor will be the last to take the strain. such as the PE line is longger than L and N.
Installation instruction of VACONN series please refer to Figure 3.4.1-2.
