Monitoring device installation

Follow the installation steps:

1. Remove the RS232 waterproof cover.
2. Switch off all the DIP next to RS232
3. Plug in the communication module.

Connecting cables

Please prepare the cable before connecting as follows.

Number| Cable name| Type| Recommend module|  Notice：
1.Lithium battery has its own power line and communication line, so use them.
2 . H y b r i d i n v e r t e r i n c l u d e t h e b a s i c communication line. So use them directly. 3.Please make sure all the switches off before connection. For your safety, please do not operation when power on.
---|---|---|---|---
1| grounding cable| Single multi-core yellow-green copper cable| Cable diameter≥AWG10
2| AC output cable| Two or three different color multi-core copper cables| Cable diameter≥AWG10
3| PV input cable| Photovoltaic dedicated cable( such as PV1-F）| 4mm² – 6mm²
4| Battery power cable| Red and black multi-core copper| Cable diameter≥AWG6
5| Other communication cable| CAT5E| /

Grounding

AC GRID and EPS output connection

DC connection

PV input terminal installation

Plug in PV terminal

Notes:

1. P l e a s e m a k e s u r e t h e P V i n p u t voltage/current not beyond the specification before plug in.
2. When installing the PV terminal, pay attention to the distinction between the positive and negative terminals and the one-t o – o n e c o r r e s p o n d e n c e b e t w e e n t h e terminals and hybrid inverter.
3. When the terminal is docked, there is a click sound. After the terminal is docked, gently pull the PV cable to observe whether the terminal is shaking or not.

Battery power line connection

Installation steps as follow:

1. Pass the battery power cables through the tightening nut, waterproof rubber plug and waterproof cover.
2. Press OT terminal at the end of cables.
3. Connect the power cable to hybrid inverter. Be careful the polarity.
4. Be careful not to tighten the tightening nut at this time. After all the communication cables are installed, tighten them together.

Communication cables installation

When all the communication lines are installed, push the waterproof cover into the bottom, lock the screws fixed to the frame, and finally lock the waterproof cap.

Post-installation check

shinelink or GPRS is installed correctly and firmly.
3| Cable wiring is reasonable, meets the requirements, no broken skin, etc.| 4| The ground wire confirms the connection and is reliable.
5| All switches off| 6| All wires are correct and securely connected.
7| Cable tie port trimming, no sharp corners, etc.| 8| All exposed terminals are well protected, no vacant ports.
9| Pay attention to packing all the residual materials.| |
