2. Screws Not Tightened Properly
⚠️ 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
-
Turn the locking nut clockwise toward "LOCK". You must hear a "click".
-
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.
