P.7-72Surge absover .................. P.7-74Noise filter for signal lines. P.7-75• About circuit breaker and magnetic contactorTo comply to EC Directives, install a circuit breaker between the power and thenoise filter without fail, and the circuit breaker should conform to IEC Standardsand UL recognized (Listed and marked).Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetricalamperes, below the maximum input voltage of the product.If the short-circuit current of the power supply exceeds this value, install a current limitdevice (current limiting fuse, current limiting circuit breaker, transformer, etc.) to limit theshort-circuit current.• Select a circuit breaker and noise filter which match to the capacity of power supply (in-cluding a load condition).• Terminal block and protective earth terminalsUse a copper conductor cables with temperature rating of 75˚C or higher.The screws of protective earth terminals for Frame A to D are M4 and M5 for Frame E, F.Fastening torque of earth screws. refer to P.1-16.Tighten the terminal block screw on frame F with a torque between 1.0 and 2.0 N·m.Application of overtorque (more than 2.0 N·m) will cause damage to terminal block.Maximum allowable torque to the screw securing terminal block cover is 0.19 to 0.21N·m.• The cable diameter of an earth cable.Use an earth cable with the same diameter or larger as that of the main circuit cable.If the diameter of the main circuit cable is 1.6mm 2 or less, use an earth cable with adiameter of 2.0mm2 (AWG14).• Use the attached exclusive connector for A to E-frame, and maintain the peeled offlength of 8 to 9mm. (Refer to P.2-19)• Tighten the screws of the connector, Connector X4 for the host controller with thetorque of 0.3 to 0.35 N·m.Larger torque than 0.35N·m may damage the connector at the driver side.Do not turn on power without tightening all terminal block screws properly, otherwise,loose contacts may generate heat (smoking, firing).2.
