Termination of cable end

Strip 9 mm (0.35") of insulation from the end of the wire. For stranded wires, terminate the
end of the wire using a wire ferrule with insulating sleeve.
Tighten the terminals to a torque of 0.4 to 0.5 N • m.
Do not tighten terminal screws with a torque outside the above-mentioned range. Failure to
do so may cause equipment failures or malfunctions.
• When using stranded wires
It may be difficult to insert the electric wire into the insulating sleeve
depending on the thickness of the electric wire sheath. Select
appropriate electric wire by referring to the dimensions of the wire
ferrule.
