Spring clamp terminal block
Wire the spring clamp terminal block in accordance with the following specifications.
For information regarding spring clamp terminal blocks for intelligent function modules and FX5 safety extension modules,
refer to the user's manuals for each module.
Suitable wiring
The wires to connect the spring clamp terminal block are described below.
Wire end treatment
When not using a ferrule, strip the cable about 10mm from the tip and connect it as a strand wire so that the wires do not
separate.
When using a ferrule, strip the cable about 10mm from the tip to connect a wire ferrule at the striped area. Failure to do so
may result in electric shock or short circuit between adjacent terminals because of the conductive part. If the wire strip length
is too short, it may result in the unstable connection to the spring clamp terminal part.
Depending on the thickness of a wiring sheath used, inserting the sheath into an insulation sleeve may be difficult. Refer to
the external dimensions as a reference to select wires.
The following table lists wire ferrules and tools used for removing this part compatible with the terminal block. Use of items
that are not listed in the following table may result in wire ferrule getting stuck to the terminals. Before use, carefully check that
the wire ferrule can be removed.
