Wiring push-in connector
Notice | |
Do not wire when live. Risk of defect.
|
The push-in connectors X001, X002 and X003 are pluggable. X004 is firmly connected to the terminal.
All connections support push-in wiring. The wiring procedure depends on the type of conductor and connector selection:
Single wires
- Strip 10 mm of insulation from the end of the conductor.
- Insert the conductor into the push-in spring connection.
Stranded or fine-stranded conductors without ferrules
- Strip 10 mm of insulation from the end of the conductor.
- Press the latch with a screwdriver.
- Insert wire.
- Relieve latch.
Stranded wire conductors and ferrules
Insert the wire end ferrule into the push-in spring connection.
The specified wire cross-sections refer to the technical properties of the push-in connectors. The selected cross-section must comply with the valid standard for the application in terms of minimum cross-section and electrical conductivity.
Possible conductor cross-sections depending on the type of cable:
For push-in connectors with 2x5 (X001) or 2x4 positions (X002 / X003 for ELM721x / ELM722x):
Wire cross-section AWG: | 24 … 16 | ||
Single wires: | 0.2 … 1.5 mm² | ||
Stranded or fine-stranded conductors without ferrules: | 0.2 … 1.5 mm² | ||
Stranded wire conductors with ferrule without insulating collar: | 0.25 … 1.5 mm² | ||
| Sleeve length of the ferrules (according to DIN 46228-1): |
| |
|
| Cross-section 0.25 … 0.34 mm²: | 7 mm |
