Overview of the product
The brake pack is a product that allows a programmable controller to perform
clockwise/counterclockwise operation and instantaneous stop of a motor as
well as release/actuation control of the electromagnetic brake. In addition, if
the brake pack detects an "open" state of the thermal protector built in the
motor, the ALARM output is turned "OFF" to prevent the motor from restarting
when the thermal protector is automatically returned.

positions. Using it for braking or as a safety brake may result in injury or
damage to equipment.
y If the ALARM output of the brake pack is turned "OFF," remove the cause
before resetting the alarm. Continuing the operation without removing the
cause of the problem may cause malfunction of the motor and/or the brake
pack, leading to injury or damage to equipment.
y Install the brake pack in an enclosure. Failure to do so may result in electric
shock or injury.
y Be sure to keep the input-power voltage of the brake pack within the
specified range. Failure to do so may result in fire or electric shock.
y Connect the cables securely according to the wiring example. Failure to do so
may result in fire 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 fire.
y Turn off 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.
y Do not disassemble or modify the brake pack. Doing so may result in electric
shock, injury, or damage to equipment. Refer all such internal inspections and
repairs to the branch or sales office from which you purchased the product.

y Before turning on the power supply, make sure to turn all control inputs of
the brake pack "OFF." Otherwise, the motor may suddenly start when the
power is turned on, leading to injury or damage to equipment.
y Provide an emergency-stop device or emergency-stop circuit external to the
equipment so that the entire equipment will operate safely in the event of a
system failure or malfunction. Failure to do so may result in injury.
y Immediately when trouble has occurred, stop operation and turn off the
power supply. Failure to do so may result in fire, electric shock, or injury.
