Specifications
R88D-KN30H-ECT-R/R88D-KN50H-ECT-R
Main Circuit Terminal Block Specifications
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).
