specied range. Failure to do so may result in re or electric shock.
y
Connect the cables securely according to the wiring example. Failure to do so
may result in re or electric shock.
y
Connect an earth leakage breaker to the power line of the brake pack to
protect the primary circuit. Failure to do so may result in re.
y
Turn o the power to the brake pack in the event of a power failure.
Otherwise, the motor having connected may suddenly start when the power
is restored, causing injury or damage to equipment.
