► Notes

1. If the junction box casing is found to be deformed, cracked or damaged, stop using it and replace it with a new one.

2. During installation, prevent short circuit between the outer braided copper wire and the heating wire and core wire, and ensure that the electrical clearance is not less than 8mm and the creepage distance is not less than 10mm.

3. When the redundant holes of the junction box are not in use, they should be blocked with a blocking plate with a thickness of not less than 2mm.

4. Connect the power supply cable to the power junction box. When the current is less than 15A, use 3×2.5mm2 rubber sheathed cable; when the current is greater than 15A, use 3×4mm2 rubber sheathed cable.

5. The power junction box is equipped with a grounding terminal for grounding the heating tape.

6. When the power grounding box is used on the buried pipe, seal it with 702 glue at the cable inlet after installation, and pay attention to waterproof sealing.
