Wiring of Terminal Unit

If the ends of the individual wires are not twisted correctly, the wires may create a short circuit.
Using a pin terminal with an insulating sleeve is recommended to prevent the possibility of a terminal short circuit.
Use copper wire rated for 75 °C (167 °F) or higher.

Recommended cross section	0.5...2.5 mm² (AWG 20...13)
Conductor type	Solid or stranded wire
Conductor length	6…7 mm (0.24…0.28 in)
Recommended pin terminals	Cross section: 0.25...1.5 mm²
Recommended screwdriver	Blade thickness: 0.6 mm (0.02 in) Blade width: 3.5 mm (0.14 in)

Insert each cord wire into its corresponding hole and fasten the screws to clamp the wire in place.

NOTE: The necessary torque is 0.4 N•m (3.5 lb-in).

Screwdriver

Installing to DIN Rail

Hook the upper groove of the unit onto the DIN rail, then push the bottom part onto the rail until you hear a click.

NOTE:

Use the DIN rail compatible with IEC 60715 TH35-7.5 for the terminal unit.
In environments where this terminal unit will experience extreme vibration and shock, affix this terminal unit to the DIN rail with compatible fasteners, as required.
