Current Reverse-phase Detection Models
Terminal Arrangement
•
Perform the external connections by referring to the examples given below.
•
Connect the phase advancing capacitors closer to the power supply than the
current transformer as shown in the examples.
•
Tighten the terminal screws to a torque of 0.98 N·m max. (The appropriate
tightening torque is 0.49 to 0.67 N·m.)
•
Use of insulated solderless terminals is recommended for connection to the
Relay terminals (M3.5).
Note: 1.
In principle, the K2CM must be surface mounted with the terminal
block facing downward.
2.
Use M5 screws with spring washers and flat washers for mounting.
Tighten the screws to a torque of 1.77 N·m max. (The appropriate
tightening torque is 1.08 to 1.57 N·m.)

Note:
Connect the phase advancing capacitor on the power supply
side of the Motor Protective Relay as shown in the above
diagrams.
