Precautions for Correct Use
 Tighten the terminal block screws to the torque of 0.75 N•m (M4) or 1.5 N•m (M5).
 If the torque for terminal block screws exceeds 1.2 N•m (M4) or 2.0 N•m (M5), the terminal block
may be damaged.
 Tighten the fixing screw of the terminal block cover to the torque of 0.2 N•m (M3).
 Tighten the ground screws to the torque of 0.7 to 0.8 N•m (M4) or 1.4 to 1.6 N•m (M5).
