(4) Internal Circuits
The brake power supply circuit can be opened and closed either on AC or DC side. However, if the wiring dis-
tance on 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 absorber model CR50500BL (sold as spark quencher) for
the brake power supply near 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 a
surge absorber. However, the surge voltage at switching may damage the brake coil. Install a surge absorber
near the brake coil to prevent the damage to the brake coil in addition to the built-in surge absorber.
