Introduction
Before using the product
Only qualified personnel should work with the product.
Use the product correctly after thoroughly reading the section “Safety
precautions.”
The product described in this manual has been designed and manufactured
for incorporation in general industrial machinery, and must not be used for
another purpose. Oriental Motor Co., Ltd. is not responsible for any damage
caused through failure to observe this warning.
This Operating Manual describes the use of brake pack. For details regarding
motor operation, please refer to the operating manual included with to the
motor.
Overview of the product
The brake pack allows a programmable controller to govern the motor’s
clockwise and counterclockwise rotations, provide instantaneous stopping
and the release and actuation control of the electromagnetic brake. Moreover,
upon detecting the built-in thermal protector triggering “open,” it prevents
the motor from restarting automatically when the ALARM output is reset to
“OFF (H level)” and the thermal protector is automatically reset.
Main features
• Complies with UL and CSA standards and CE marking
The brake pack is recognized by UL, and has declared its conformance with
the CE marking.
• Compatible with programmable controllers
The signal-input and signal-output parts adopt a 24 VDC photocoupler input
and an open collector, respectively.
• Preventing the motor from restarting upon recovery of the thermal
protector
The brake pack shuts off the motor power in order to prevent it from
automatically restarting, even when the motor cools down and the thermal
protector resets to the “closed” state.
Safety standards
The brake pack is recognized by UL.
• Standards UL508, CSA C22.2 No.14
Standards File No.E91291
• Applications for standard EN50178, EN60950
• Installation conditions Overvoltage category II,
Pollution degree 2 (For EN standard)
• Conformance with the EC directives
This product conforms with the EC’s low voltage directive and EMC
directive under the following conditions.
Take the following measures to ensure conformance with the EC’s low
voltage directive and EMC directive.
For low voltage directive
This product is designed for use as a built-in component.
• Install the product within an enclosure in order to avoid contact with the
hands.
For EMC directive
This product has received EMC measures under the conditions specified in
“Example of motor and brake pack installation and wiring” on page 7. Be
sure to conduct EMC measures with the product assembled in your
equipment by referring to “Installing and wiring in compliance with EMC
directive” on page 6.
Note • The overvoltage protection test, as required under
EN50178, is not performed. The customer is required to
conduct the test on the final product incorporating the
unit.
• When the brake pack is used with the K series motors,
the brake pack is not in conformance with any safety
standards.
Safety precautions
The precautions described below are intended to prevent danger or injury to
the user and other personnel through safe, correct use of the product. Read
the body of the text based on a sufficient understanding of its importance.
Warning
Handling the product without observing the

Handling the product without observing the
instructions that accompany a “Caution” symbol
may result in injury or property damage.
Note
The items under this heading contain important
handling instructions that the user should observe to
ensure the safe use of the product.
Warning
• Do not use the product in explosive or corrosive environments, in the
presence of flammable gases, locations subjected to splashing water, or
near combustibles. Doing so may result in fire, electric shock or injury.
• Assign qualified personnel the task of installing, wiring, operating/
controlling and inspecting the product. Failure to do so may result in fire,
electric shock or injury.
• Do not transport, install the product, perform connections or inspections
when the power on. Always turn the power off before carrying out these
operations. Failure to do so may result in electric shock.
• Do not use the brake pack as a safety device. Doing so may cause fire,
electric shock, injury or damage to equipment.
• Do not use the motor’s built-in electromagnetic brake mechanism for
stopping or safety purposes. Using it for purposes other than holding the
moving parts and motor in position may cause injury or damage to
equipment.
• When the ALARM output goes “OFF (H level),” shut off the power
immediately. Turn the power back on only after removing the cause of the
ALARM. Continuing the operation without removing the cause of the
ALARM may cause the brake pack to malfunction, leading to injury or
damage to equipment.
• Place the brake pack in its enclosure in order to prevent electric shock or
injury.
• Keep the brake pack’s input-power voltage within the specified range to
avoid fire and electric shock.
• Connect securely according to the wiring diagram in order to prevent fire
and electric shock.
• Turn off the power to the brake pack in the event of a power failure, or the
motion interface will suddenly start when turning the power back on and
may cause injury or damage to equipment.
• Do not disassemble or modify the brake pack. Refer all such internal
inspections and repairs to the branch or sales office from which you
purchased the product.
