5. Lift up the inverter.
6. Two methods are available by four installers or lifting right
7.  Hang it onto the bracket.
8. Fix it on the stand with M8 bolts.(Torque: 7.0-8.5 N·m)

Grounding connection

1. Select 35-70 mm² ground conductor and OT copper terminal
2. Strip the insulation end of cable with proper length
3.  Pull the heat-shrink tubing over grounding cable
4. Insert the stripped section into OT terminal.
5. And crimp with crimping tool
6. Pull the heat-shrink tubing onto crimped section of OT terminal
7. The tubing must be at below stripped cable section
8. Use hot-air blower to shrink it so that they are in firm contact with OT terminal
9. Connect the grounding cable to grounding point on the inverter
10. Tighten it with torque 7.0-8.5 N·m

Grid connection

1. Select the appropriate OT terminal and 70~240 mm² copper cable

2. Use wire stripper to strip the insulation layer of the AC cable end.

3. The stripped insulation layer shall be 2-3mm longer than “D” part of OT terminal as shown below.
   Note : The “Delta Grid” in “Setting”-”Grid Protection”- “FunctionChoose” is set as “Enable” in default.
   In this condition, the Neutral wire is not required to be connected.
   Please set “Delta Grid” to “Disable” before connecting the Neutral wire for 40 kW-70 kW / 80 kW-125 kW inverter.

4. Pull the heat-shrink tubing over AC cable.

5. Insert the stripped section into OT terminal and crimp with crimping tool.

6. Pull the heat-shrink tubing over the crimped section of OT terminal.

7. Use hot air blower to shrink it so that they are in firm contact with OT terminal.

8. Un-install the screws on the cover to open the cover of the wiring box.

9. Use utility knife to cut out the pagoda type protection ring in accordance with the whole cable size,

10. Put the AC cable through the pagoda protection ring, and connect it to the AC terminals L1, L2, L3 and N in turn, and tighten it with torque wrench (with the torque of 25-30 N·m).

11. Re-install the cover of wiring box with the torque of 5~7 N·m.

PV connection
Disassemble the DC connector

Connect the PV cable to the corresponding PV port

Communication connection

1. Select 0.5~0.75 mm² twisted-pair and strip the 20-pin communication insulation
2. Insert the insulated cord end terminal into the cable end 20-
3. (ENY0512 nylon terminal for 0.5mm²/22 AWG conductor;
4. ENY7512 nylon terminal for 0.75 mm²/20 AWG conductor)
5. Clamp with terminals press clamp
6. Disassemble the communication terminal
7. Set the nut, claw, seal body, seal ring and body on the cable
8. Insert the tube type terminal into the housing according to the label
9. Push the terminal-inserted housing into the body; you will hear “Click” , if it is correctly inserted
10. Please check the following table for more details about corresponding Pin definition

1. Push the seal body into seal ring, then push the claw
2. Clockwise tighten the nut with torque 8+/-2 N·m
3. Keep the buttons on both sides pressed and then connect it to the communication port on the inverter. You will hear
   “Click” if it is correctly connected

Monitoring connection

• Monitoring Cloud is an application that can communicate with the inverter via Wi-Fi/LAN/4G. It can realize alarm query, parameter configuration, daily maintenance and other functions. This is a convenient maintenance platform.

• Plug Dongle into “USB” port at the bottom of the inverter. After the DC side or AC side is powered on, the APP and inverter can be connected. Please refer to the corresponding manual for details.

• Wi-Fi connection
  WiFi dongle connects to a local network within 50 m of the installation to enable access to the Monitoring Cloud platform.

• LAN connection
  If Wi-Fi isn’t suitable, the LAN dongle enables users to connect to the network via an ethernet cable. Ethernet allows for a much more stable connection with less interference.
  

Monitoring connection

4G connection
4G dongle allows you to use a 4G connection to monitor your system without the option of connecting to a local network. (This product is not available in the UK)

• Basic setting
  Basic settings can set the time, date and language.

• Advanced setting
  Advanced settings can set “Safety”, “System Switch”, “PVConnection”, “Active Power Control”, “Export Control”, “Reactive Power Control”, “Grid Voltage Parameters” “Grid Frequency Parameters”, “Grid Through Parameters”, “Check Parameters”, “Reset”, “Communication Parameters” and “New Password”.
