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 the
electric wire by referring to the dimensions of the wire ferrule.
