Page 14 5 Electrical Connec�on 5.1 DC input terminal connec�on 1. Switch the Grid Supply Main Switch(AC)OFF. 2. Switch the DC lsolator OFF. 3. Assemble PV input connector to the inverter. Safety Hint: Please don’t connect PV array posi�ve or nega�ve pole to the ground, it could cause serious damages to the inverter.
Page 15 The steps to assemble the DC connectors are listed as follows: a) Strip oﬀ the DC wire about 7mm, disassemble the connector cap nut (see picture 5.3). Pic 5.3 Disassemble the connector cap nut b) Crimping metal terminals with crimping pliers as shown in picture 5.4. Pic 5.4 Crimp the contact pin to the wire c) Insert the contact pin to the top part of the connector and screw up the cap nut to the top part of the connector.

Page 19 5.3 The connec�on of the ground line Good grounding is good for resis�ng surge voltage shock and improving EMI perfor- mance.Therefore, before connec�ng AC, DC and communica�on cables, you need to ground the cable ﬁrstly. For a single system, just ground the PE cable. For mul�ple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipoten�al connec�on.
Page 20 In order to protect the inverter AC connec�on, it is recommended to install a circuit breaker to prevent overcurrent. See table 5.3 below.

Page 21 5.6 Installa�on of datalogger When the inverter is out of the factory, the installa�on loca�on of datalogger is sealed by a sealed plate as shown in Picture 5.13. When installing the datalogger, remove the sealing plate, replace it with the sealing plate with square hole in the accessories, and �ghten the screws. Insert the datalogger into the interface and ﬁx it with a screw.
Page 22 6. Startup and Shutdown Before star�ng the inverter, make sure that the inverter can meet the following condi�ons, otherwise it may result in ﬁre or damage to the inverter. In this case, we do not undertake any responsibility. At the same �me, to op�mize the system conﬁgura�on, it is recommended that the two inputs be connected to the same number of photovoltaic modules.
Page 23 7 Zero export func�on via SUN limiter The inverter has external zero export func�on. This func�on is op�onal. It can collect counter- current power to control the output power of the inverter, so that the power of inverter and load can be oﬀset, and the excess power will not be fed back to the grid. If you purchase the inverter with zero export func�on, an external zero export device ( SUN limiter or energy meter) will be included in the package which is necessary for the func�on.The SUN limiter shows as Pic 7.1.You can see corresponding line mark next to the green interface.
Page 24 We recommend installing an AC switch between the inverter outlet and the u�lity grid, the specs of the AC switchis determined by the load capacity. The AC switch we recommend to connect to the inverter output refer to Table 5.2. L1(L) Solar panels L1(K)

(4) Connect the control line. There are two numbers 1 and 2 on the interface of SUN limiter, and the same on the waterproof terminal of the inverter.
Page 26 Pic 7.7 Connect terminal to inverter 7.3 Use of zero export func�on When the connec�on is completed, the following steps should be referenced to use this func�on: 1. Turn on the AC switch 2. Turn on the DC switch, Wai�ng inverter LCD ligh�ng up 3.
