2. System Configuration and Wiring
Driver and List of Applicable Peripheral Equipments
• Select peripheral equipments for single/3phase common specification according to the
power source.
[For details of peripheral equipments]
Noise filter ......................... P.7-72
Surge absover .................. P.7-74
Noise filter for signal lines . P.7-75
• 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 delivering not more than 5,000 rms symmetrical
amperes, below the maximum input voltage of the product.
If the short-circuit current of the power supply exceeds this value, install a current limit
device (current limiting fuse, current limiting circuit breaker, transformer, etc.) to limit the
short-circuit current.
Remarks
• 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 terminals
Use 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 0.21
N·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
diameter of 2.0mm
• Use the attached exclusive connector for A to E-frame, and maintain the peeled off
length of 8 to 9mm. (Refer to P.2-19)
• Tighten the screws of the connector, Connector X4 for the host controller with the
torque of 0.3 to 0.35 N·m.
Larger torque than 0.35N·m may damage the connector at the driver side.
Caution
Do not turn on power without tightening all terminal block screws properly, otherwise,
loose contacts may generate heat (smoking, firing).
