Placing Brake on Motor Shaft

1. Remove cover. Place gasket on the motor mounting face.

Position brake over hub on shaft, aligning hub splines

with rotating friction disc splines. Drain plug to face

down on horizontal models.

NOTE: For model 6-60000-535 a second gasket is

positioned between the bracket and adapter bracket.

If gasket does not make contact around the mounting

face completely (360

RTV sealant around the mounting bolt holes to

approximately 1" dia. Use Dow Corning #739 RTV

only; other types may form acetic acid during curing

if subjected to water or high humidity. This will

cause premature failure of zinc plated parts.

If tapped holes in motor for mounting bolts are not

totally enclosed, place RTV sealant around threads

before bolting brake to motor. Use Dow Corning

#739 RTV only.

If water can accumulate in the cavity between the

v-ring hub assembly and fan guard or other unsealed

mounting face to the height of the v-ring seal, drill a

hole in the fan guard or other equipment so the water

drains out.

Tighten mounting bolts to 25 lb. ft. torque.

3. Connect coil leads as outlined under "Connection of Coil

Leads" and Fig. 3.

4. Let RTV #739 cure 24 hours before replacing cover.

5. Replace cover . Tighten cover screws to 5 lb. ft. torque.

Connection of Coil Leads

After securing the brake to the motor, connect coil leads for

proper voltage per wiring diagram (Fig. 5 shows dual voltage

coil). Incorrect connection can result in brake failure.

CAUTION: The voltage supplied to the coil must match

the voltage that the coils are connected for, or the coils

will burn out.

Wiring Diagrams

), remove gasket and place

Single voltage coil:

Connect brake coil leads to any two line leads (single or three

phase) of same voltage and frequency as brake.

Dual voltage coil:

Connect leads 2 and 4 to any two motor line leads (single or

three phase) of same voltage as brake. Connect leads 1 and 3

as shown for voltage desired. Brake must be energized with

motor.

OPERATION

These brakes are spring set devices with an electrical

(magnet) release. They contain a rotating friction disc

that is driven by a hub mounted on the motor shaft. When

energized, the magnet compresses the torque springs,

removing the force pressing the stationary disc and friction

disc together. This permits free rotation of the shaft.

WARNING: Observe proper safety precautions in

applications where a brake failure would allow the load

to move in such a manner as to injure personnel.

KEEP PERSONNEL AWAY FROM LOAD AREAS.

If brake torque rating is higher than motor full-load torque

rating, use brake rating rather than motor rating when

selecting other drive components.

Take the following precautions when operating the brake:

1. Do not operate the brake at higher than nominal static

torque capacity.

2. For applications with high inertia-type loads or rapid

cycling, the thermal capacity of the brake must be

considered.

3. High start-stop rates may damage motor. Consult motor

manufacturer if high cycling rates are expected.

4. Be sure power supply conforms to electrical rating of

brake.

Manual Release

The brake is equipped with a manual release. Turn the release

knob clockwise to stop position to release the brake. The

brake will remain released until the release knob is turned

counterclockwise (approx. 65

energized, automatically resetting the brake.

) or until the brake coil is
