Features
• In the case of terminal modules with Fast Connect, the individual wires are
attached using a quick connection method that requires no stripping.
• Fast Connect is a connection method that requires no preparation (i.e. the
conductor does not have to be stripped).
• Each terminal of the terminal module with Fast Connect has a test opening (for
measuring the voltage, for example). The test opening is suitable for test
probes with a maximum diameter of ∅ 1.5 mm.
• Wire end ferrules are not permitted.
