Warning

DC Side

1. Ensure the component frames and the bracket system are securely grounded.
2. Connect the DC cables using the delivered DC connectors and terminals. The manufacturer shall not be liable for the equipment damage if other connectors or terminals are used.
3. Ensure the DC cables are connected tightly and securely.
4. Measure the DC cable using the multimeter to avoid reverse polarity connection. Also, the voltage should be under the permissible range.

AC Side

1. The voltage and frequency at the connecting point should meet the on-grid requirements.
2. An additional protective device like the circuit breaker or fuse is recommended on the AC side. Specification of the protective device should be at least 1.25 times the AC output rated current.
3. PE cable of the inverter must be connected firmly. The resistance between the neutral wire and the earth cable is less than 10Ω.
4. You are recommended to use copper cables as AC output cables. Contact the manufacturer if you want to use aluminum cables.

Inverter Side

1. Terminals at the bottom of the inverter cannot bear much load. Otherwise, the terminals will be damaged.
2. All labels and warning marks should be clear after the installation. Do not scrawl, damage, or cover any label on the device.
3. Warning labels on the inverter are as follows.

| High Voltage Hazard. Power
off the inverter first before any operations.| | Potential risks exist. Wear
proper PPE before any
operations.
---|---|---|---
| Read through the guide before

and easyto-operate.
2| The PE cable, DC input cable, AC output cable, and communication cable are connected correctly and securely.
3| Cable ties are routed properly and evenly, and no burrs.
4| Unused ports and terminals are sealed.
5| The voltage and frequency at the connection point meet the on-grid requirements.
