Wiring
• In case of 3-Phase 200 V
In wiring to power supply (outside of equipment) from MCCB, use an electric wire of
1.6 mm diameter (2.0 mm
2
) or more both for main circuit and grounding.
Please ground with grounding resistance less than 100 Ω.
Do not tighten the ground wires together, but connect them individually.
Fastening torque of earth screws to be 0.8 to 1.2 N·m.
When extending the motor
wires, use the optional
motor extension cable.

How to wiring:
Please use a single wire or rod terminal and insert as far into the connection hole.
Recommended rod terminal: TGN TC-1.25-9T(NICHIFU), Applicable wire size: AWG20 to 16.
In case of single wire: Strip length 10 mm (reference): Applicable wire size: AWG20 to 14.
10 mm
* Please check tools etc. necessary for terminal crimp on the home page of terminal
manufacturer or contact terminal manufacturer.
* Since the strip length of the wire depends on the type of wire etc., please decide the
optimum strip length according to the processing condition.
CAUTION: To prevent unforeseen circumstances due to poor contact etc., install and wire so
that no stress such as pulling is applied to the terminal block through the cable.
How to remove wiring: Right figure
Using a flathead screwdriver with a blade width of 2.6 mm,
push the Wire extraction button of the terminal block verti-
cally and remove the electric wire. Be careful not to apply
excessive force at this time. (Approximately 20 N or less)
