1. Bare Wire Connection

2. Screws Not Tightened Properly

3. Connector Not Fully Locked

4. Cable Bent Too Sharply

⚠️ Warning:

Improper wiring or installation can cause connectors to melt, potentially leading to equipment damage and property loss.

NOTE

The AC Grid connector is used as an example; the procedure for the AC Backup connector is identical.

1. Bare Wire Connection

⚠️ WARNING:

• Wire ferrules are required! Do NOT use bare wires. Bare wires cause bad connections, leading to overheating and melted connectors.

• Recommended AC Cable: 6 mm².

2. Screws Not Tightened Properly

Wires must be screwed down tightly to prevent loose connections (Required torque: 0.8 ± 0.1 N·m).

3. Connector Not Fully Locked

1. Turn the locking nut clockwise toward "LOCK". You must hear a "click".

2. To check: Gently pull back on the connector to make sure it won’t come out.

4. Cable Bent Too Sharply

⚠️ WARNING: Sharp bends near the plug break the waterproof seal and loosen the connection. This will cause overheating and melt the connector!

Multi-Core Cable Rules

• Keep it straight: Do not bend for 100–150 mm after the nut.

• Max angle: Do not bend more than 90°.

• Safe radius: Bend radius ≥ 10 × cable diameter.

• Tie it down: Secure the cable at the bend to prevent stress.
