Read carefully before attempting to assemble, install, operate or maintain
the product described. Protect yourself and others by observing all safety
information. Failure to comply with instructions could result in personal injury
and/or property damage! Retain instructions for future reference.
DESCRIPTION
These magnetic disc brakes mount directly onto NEMA182TC, 213TC, and
256TC frame motors, on the end opposite the drive shaft. The brake is direct
acting, electro-magnetically released, and spring set. It uses rotating friction and
stationary disc contact to supply positive braking action. It retains quick release
and setting capabilities at all times.
WARNING: Do not install or use these brakes in an explosive atmosphere.
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. Do not activate the
manual release without the hub inserted in the discs as doing so may result in loss of disc spline alignment.
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) & the Occupational
Safety and Health Act (OSHA).
3. Brake motors & brake gearmotors must be securely & 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 & voltage.
8. Protect all electrical lead wires & power cables against contact with sharp objects or moving parts.
9. Do not kink electrical lead wires & power cables, and never allow them to touch oil, grease, hot surfaces, or chemicals.

RECOMMENDED TOOLS AND HARDWARE
NOTE: The following tools and hardware are required for installing the brake onto a motor or mounting bracket. Use
proper torque when required to ensure fasteners do not loosen during operation.
• 3/4 INCH HEX WRENCH OR RATCHET/SOCKET
• 3/16 HEX BIT SOCKET (OR KEY)
• TORQUE WRENCH
• QUANTITY (4), 1/2 diameter SHCS, MINIMUM 1” LONG (see installation note #5 below)
• 3/8 BALL END HEX BIT SOCKET (KEY OR T-HANDLE)
INSTALLATION
(See Figures 1, & 2, Table 1)
1. Remove hub (99) from brake and position on motor shaft with key according to dimension “N” per figure 1.
Stamped part number on hub should face away from motor. Tighten hub set screws with 18 lb.ft. torque.
2. Remove temporary cover nut and cover (67). Set cover aside. Discard temporary nut.
3. If brake is supplied with a mounting face gasket (91), place gasket onto the brake mounting face.
4. Place brake on motor, guiding discs on hub. Use caution not to pinch gasket. For horizontal mounted brakes, the
drain plug should be pointed down.
5. Bolt brake to motor “C” face with four socket head cap screws. See Figure 1 to help in determining proper bolt
length. Final bolt thread pitch, length and mounting torque is dependent on the material and depth of the threaded
holes in the mounting face.
6. Connect coil leads per appropriate wiring diagram in Figure 1 and replace cover (67).
7. Use provided sealing washers (70) and nylon locking nuts (71) to secure cover (67).

MAINTENANCE
CAUTION: Before attempting to service or remove any components, make certain that the power is disconnected and
that the load is completely removed, secured or blocked to prevent injury or property damage.
Wear Adjustment
CAUTION: Load to be removed or blocked. Brake may be inoperative during this procedure.
Before air gap “D” reaches .100”, adjustment is required. Any delay in adjusting
the magnet air gap will result in eventual loss of torque. Refer to Fig. 1, 2 & 3.
1. To adjust, remove cover locknuts/seals (70 & 71) and cover (67) to expose
wear adjusting screws on item (32) and expose magnet air gap “D”.
2. Measure air gap “D” using 3/8” to 1/2” wide feeler gauge.
Measure at center of magnet.)
3. Turn two adjusting screws on item(32) until air gap “D” measures:
.035/.045 for 1 disc models
.035/.045 for 2 disc models
.045/.055 for 3 disc models
.055/.065 for 4 disc models
Air gap should be the same on both sides.
Torque Adjustment
Caution: Load to be removed or blocked. Brake may be inoperative during this procedure.
The magnetic disc brake is factory set for rated static torque. The brake can be adjusted to reduce torque which increases
stopping time. Do not attempt to adjust brake for higher torque, as this will cause premature coil burnout. (Refer to Fig. 1 & 2)
1. To adjust, remove cover locknuts/seals (70 & 71) and cover (67) to expose torque locknuts (44), which are above torque
springs (42).
2. To increase stopping time and reduce torque, turn two locknuts (44) counterclockwise, increasing spring length.
Each full turn reduces torque 7% to 10% depending upon the model.

VERTICAL MOUNTING
Installation and Adjustment
Installation and adjustment of the
vertically mounted brake is the same as
on the standard model.
Friction Disc Replacement
When replacing friction discs, follow
procedure outlined on page 3 with this
addition:
Care must be taken to insure proper
insertion of disc separating springs.
Springs are color coded for easy
identification, and reference is made to
spring color (See table to the right &
diagram below). Since the installation
order of the disc springs is dependent on
brake mounting position (above or below
motor), it is important to consult the
correct diagram for spring location.
