*1 Select peripheral equipments for single/3phase common specification according to the power source.
*2 For the external dynamic brake resistor, use the magnetic contactor with the same rating as that for the main circuit.
*3 When use the external regenerative resistor of the option (DV0PM20058, DV0PM20059), use the cable with the same diameter as the main circuit cable.
*4 Use these products to suit a standard.

• About circuit breaker and magnetic contactor

  
  To comply to EC directives, install a circuit breaker between the power and the noise filter without fail, and the circuit breaker should conform to IEC Standards and UL recognized (Listed and marked).
  Suitable for use on a circuit capable of deivering not more than 5,000 Arms symmetrical amperes, below the maximum input voltage of the product.
  Remarks → Select a circuit breaker and noise filter which match to the capacity of power supply (including a load condition).

• Terminal block and protective ground terminals

  • Use a copper conductor cables with temperature rating of 75 °C or higher.
  • Use the attached exclusive connector for A to E-frame, and maintain the peeled off length of 8 to 9 mm. (Refer to P. 2-31)

• Fastening torque list (Terminal block screw/Terminal over fastening screw)

  Driver		Terminal block screw		Terminal cover fastening screw
  Frame	Terminal name	Norminal size	Fastening torque (N•m)Note 1	Nominal size	Fastening torque (N•m)Note 1
  F	L1, L2, L3, L1C, L2C, P, RB, B, N, U, V, W	M5	1.0 to 1.7	M3	0.19 to 0.21

• Fastening torque list (Ground terminal screw/Connector to host controller (X4))

  Driver frame	Terminal block screw		Connector to host controller (X4)
  	Nominal size	Fastening torque (N•m)Note 1	Nominal size	Fastening torque (N•m)Note 1
  A to E	M4	0.7 to 0.8	M2.6	0.3 to 0.35
  F	M5	1.4 to 1.6

  Caution → Note:1

  • Applying fastening torque larger than the maximum value may result in damage to the product.
  • Do not turn on power without tightening all terminalk block screws properly.
  • Do not turn on power without tightening all the terminal block screws properly, otherwise, loose contacts may generate heat (smoking, firing).
  • To check for looseness, conduct periodic inspection of fastening torque once a year.
  Be sure to conduct wiring properly and securely. Insecure or improper wiring may cuase the motor running out of control or being damaged from overheating. In addition, pay attention not to allow conductive materials, such as wire chips, entering the driver during the installation and wiring.
