However, if the wiring distanceon DC side is too long, the brake circuit may not operate normally due to the influence of switching noises.When switching the circuit on AC side, install a surge suppressor model CR50500BL for the brake power supplynear the brake coil to reduce the influence of switching noises.When switching the circuit on DC side, the influence of the switching noise is minimal, even without installing asurge suppressor. However, the surge voltage at switching may damage the brake coil. Install a surge suppressornear the brake coil to prevent the damage to the brake coil in addition to the built-in surge suppressor.(a) Internal Circuit for 200 VACBrake Power Supply Model: LPSE-2H01YellowRedAC side180 to 230 VWhiteSurge suppressorDiodeSurge suppressorDC (Brake) sideNo polarityBlack5-67
