Warner Electric’s FBB series of Electrically
Released Brake Modules are designed for
brake only applications when mounted to the
front of a NEMA C-face motor. The fail safe
brake engages when power goes off.

Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal injury
to personnel.
If brake is to be applied with
the brake output shaft in a vertical position
Warner Electric's application engineering
should evaluate application.
Mounting Instructions
Step 1: Mounting the Brake to a Motor
The brake module can be mounted directly to
the motor as follows:
A. Insert a key in the motor shaft keyway. Prick
punch the end of the motor shaft keyway to
prevent the key from sliding out.
B. Align the motor shaft and key with the mating
shaft hole and key slot in the brake module.
C. Slide the module onto the motor shaft so the
module surface is snug against the motor
face. NOTE: Brake Module should slide
freely onto shaft and fit flush with motor
C-face.
D. Secure the brake module in the motor C-face
with the four (4) long hex head capscrews.
Suggested torque for capscrews is 30-35
lb.ft.

adjustments or application questions arise

central time.
Step 2: Electrical Connections and
Control Requirements
A. The wiring diagram included with each
Warner Electric control shows the proper
electrical connections to be made.
B. Controls used must have adjustable output
voltage.
C. All Permanent Magnet Type Electrically
Released Brake Modules are polarity
sensitive. Therefore, the (+) red wire must be
connected to the (+) terminal and the
(-) black wire to the (-) terminal.
90 Volt Brake recommended controls are:
CBC-160-1
CBC-160-2
CBC-200
CBC-300
CBC-500-90
CBC-550-90
24 Volt Brake recommended controls are:
CBC-500-24
CBC-550-24

Step 3: Burnishing and Maintenance
. No burnishing required, units are
A
pre-burnished at factory.
B. Improper voltage setting can reduce the
braking life.
C. Wear grooves appear on the friction surfaces.
This is a normal wear condition, and does not
impair functioning of the unit. Never machine
the friction surfaces to remove grooves or
score marks resulting from normal wear.
D. Excessive heat and high operating
temperatures are causes of rapid wear.
Units should be ventilated as efficiently
as possible.
E. If brakes are used on machinery where fine,
abrasive dust, chips or grit are dispelled,
brake should be shielded.
F. Where brakes are used near a possible oil
contamination source, brake should be
shielded.
G. Oil and grease accidentally reaching the
friction surfaces may be removed by wiping
with a rag dampened with a suitable cleaner,
which leaves no residue. In performing this
operation, do not drench the friction material.
If the friction materials have been saturated
with oil or grease, no amount of cleaning will
be effective. Replace brake.
No power is applied to motor
during this procedure. Power normally
supplied by motor to brake control should
be supplied by alternate method.
1. With power off, connect the positive lead of
the power supply to the positive (red) lead of
the brake and the negative lead of the power
supply to the negative (black) lead of the
brake.
2. Connect a volt-meter to measure the voltage
applied across the brake.
3. Adjust the power supply to its lowest
possible output, then energize the power
supply only, to apply power to the brake.
4. Starting from the low point, slowly increase
the applied voltage until the brake armature
disengages from the magnet. Note and
record the applied voltage at this point.
5. Continue to slowly increase the applied
voltage until the armature re-engages the
magnet. If the maximum voltage available
from the supply does not cause the armature
to re-engage, the armature should be
manually assisted into engagement.
NOTE: If armature needs to be manually
assisted, armature should be pressed on
back side to make contact with friction
face of magnet.
Brake Release Adjustment
6. With the armature re-engaged, slowly reduce
the applied voltage until the armature

load to be free to move. Be sure the load is in
a safe condition before proceeding with this
process.
7. The optimum release point for the brake is
half-way between the two recorded voltage
readings. Adjust the supply to this optimum

the adjustable power supply to the optimum
release point of the brake. A volt-meter is
required to perform the procedure.
release voltage.
NOTE: The above procedure should be
done by visually watching the armature
move and may be repeated if necessary
from Step 1 through Step 7.
