A fast-operating fuse may blow out when the power is turned ON.3.8.2 Wiring for Noise Control1) Example of Wiring for Noise Controla) This Servopack uses high-speed switching elements in the main circuit. It may re-ceive “switching noise” from these high-speed switching elements if wiring or ground-ing around the Servopack is not appropriate. To prevent this, always wire and groundthe Servopack correctly.b) This Servopack has a built-in microprocessor (CPU). To protect the microprocessorfrom external noise, install a noise filter in place.3
