Connecting the conductor the CAGE CLAMP®
The CAGE CLAMP® connection is used to connect the conductor for system supply and supply of the various
components of the I/O modules The CAGE CLAMP® connections are designed for single-, multiple- or fine-wire
conductors.
Only connect one conductor per CAGE CLAMP®
You may only connect one conductor to each CAGE CLAMP® connection. Multiple individual conductors may
not be connected to one connection. If multiple conductors need to be placed on one connection, connect them
using upstream wiring.
Requirements:
☐ Conductor cross-section, single-wire: 0.08 mm² to 2.5 mm² (AWG 28 to AWG 14)
☐ Conductor cross-section, fine-wire: 0.25 mm² to 2.5 mm² (AWG 24 to AWG 14)
☐ Insulation stripping length: 8 mm to 9 mm (0.315 in to 0.354 in)
