WARNING:
Brake performance and features must be carefully matched to the requirements of the application.
Consideration must be given to torque requirements, especially where an overhauling condition exists, as well as thermal capacity, ambient temperature, atmospheric explosion hazards, type of enclosure and any other unusual conditions.
Improper selection and installation of a brake and/or lack of maintenance may cause brake failure which could result in damage to property and/or injury to personnel.
If injury to personnel could be caused by brake failure, additional means must be provided to insure safety of personnel.
UNPACKING
When unpacking the brake, inspect it carefully for damage that may have occurred during transit.
GENERAL SAFETY INFORMATION
NOTE: These brakes are not intended for accurate positioning applications. They are designed for applications that require rapid stopping and holding power, such as on conveyors, door openers, etc.
1. For applications with high inertia-type loads or rapid cycling, the thermal capacity of the brake must be considered.
2. Observe all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
3. Brake motors and brake gearmotors must be securely and adequately grounded. This can be accomplished by wiring with a grounded metal-clad raceway system, by using a separate ground wire connected to the bare metal of the motor frame, or other suitable means. Refer to NEC Article 250 (Grounding) for additional information. All wiring should be done by a qualified electrician.
4. Always disconnect power before working on or near a brake motor, a brake gearmotor, or its connected load. If the power disconnect point is out of sight, lock it in the open position and tag it to prevent unexpected application of power.
5. When working on the brake, be sure the load is completely removed, secured or blocked to prevent injury or property damage.
6. Provide guarding for all moving parts.
7. Be careful when touching the exterior of an operating motor, gearmotor or brake. It may be hot enough to cause injury or to be painful. This condition is normal for modern motors, which operate at higher temperatures when running at rated load and voltage.
8. Protect all electrical lead wires and power cables against contact with sharp objects or moving parts.
9. Do not kink electrical lead wires and power cables, and never allow them to touch oil, grease, hot surfaces or chemicals.
INSTALLATION
CAUTION: To preserve pre-alignment of rotating discs for ease of installation, do not operate manual release or energize brake coil before installation.
NOTE: The brakes are designed for horizontal mounting. Modification is required for vertical mounting. Brakes that are modified will have a prefix on the model number of VO (Vertical Over), VU (Vertical Under), or V (Vertical Over or Under).
On enclosed models, the brake drain should be located at the bottom. If the application causes excessive condensation build-up, vertical mounting below the motor is not recommended.
Number in parentheses refer to parts illustrated in Figs. 3, 4, 6, 7 and 10.
Placing Brake on Motor C Face
For models with two-piece shaft design:
1. Mount hub (22) over key on motor shaft 1/4” from the motor mounting face as shown in Fig. 1. Part number on hub to face away from motor. Use 3/16” square key furnished. Key must extend to, and be flush with, end of motor shaft. Tighten both setscrews in hub with 8 to 10 lb. ft. torque.
2. For enclosed housing models (4-60000-553), place gasket (34) on motor C face.
3. Remove adapter housing (7). You may have to remove wrap cover (9) and tap lightly with a soft mallet in the openings in the side of the adapter housing. Place the brake assembly onto the motor C face, engaging hub splines into brake disc splines. The release should be located at the top.
4. Screw in four 3/8-16 threaded rods (28) or (32) through bracket (1) into motor C face (approx. 9/16” engagement or 9 turns). Bring coil lead wires out of conduit hole before installing the adapter housing. Align adapter housing (7) with four threaded rods. NOTE: Arrow head on adapter housing should be in line with manual release knob (15); see Fig. 10.
Slide adapter housing onto threaded rods. turning output shaft (8) so that the keyway in the brake shaft lines up with the key in the motor shaft. Make sure adapter housing seats against the bracket (1).
Tap adapter housing in place lightly. If excessive force is required, the key may have to be filed.
5. If additional equipment is to be used, such as a gear reducer, install a key into the brake shaft extension. For enclosed housing models (4-60000-553), install gasket (34) onto the brake C face.
Slide equipment onto threaded rods, aligning key in the brake shaft with keyway in the additional equipment.
Fasten with lockwashers (29) and nuts (30).
6. If no additional equipment is used, fasten adapter housing (7) with items (29) and (30). The threaded rods may be cut off the suit the application.

For models with one-piece shaft design:
1. Place 3/16” square key furnished into motor keyway. Key must extend to, and be flush with, end of motor shaft. For enclosed housing models (4-60000-553), place gasket (34) on motor C face.
2. Place brake assembly onto the motor shaft, aligning the brake shaft keyway with key in the motor shaft. If the key wants to ride up at the end of the motor shaft keyway, push the key into the brake shaft with a screwdriver.
Do not use excessive force to seat the brake against the motor. If excessive force is required, the key may have to be filed.
Brake bracket (1) must be flush with the motor mounting face and adapter housing (7) must seat against the bracket (1).
NOTE: Arrow head on adapter housing should be in line with manual release knob (15); see Fig. 10. The release should be located at the top.
3. Screw in four 3/8-16 threaded rods (28) or (32) through housing (7) and bracket (1) into motor C face (approx. 9/16” engagement or 9 turns).
4. If additional equipment is to be used, such as a gear reducer, install a key into the brake shaft extension. For enclosed housing models (4-60000-553), install gasket (34) onto the brake C face.
Slide equipment onto threaded rods, aligning key in the brake shaft with keyway in the equipment. Fasten with lockwashers (29) and nuts (30).
5. If no additional equipment is used, fasten brake assembly with items (29) and (30). The threaded rods may be cut off to suit the application.
Connection of Coil Leads
After securing the brake to the motor, connect coil leads for proper voltage per wiring diagram. (Fig. 2 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.
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 PERSONNELAWAY 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 (15) clockwise to stop position to release the brake. The brake will remain released until the release knob is turned
counterclockwise (approx. 65
o
) or until the brake coil is
energized, automatically resetting the brake.
