Brake Instructions
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. When unpacking the brake, inspect it carefully
for damage that may have occurred during transit.

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.
Do not operate manual release or energize brake coil before installation, in
order to preserve prealignment of rotating discs for ease of installation.
DESCRIPTION
This brake is direct acting, electromagnetically released and spring
set. It uses rotating and stationary disc contact to supply positive
braking action. It retains quick release and setting capabilities at all
times.
Simplicity of design has reduced maintenance to an absolute mini-
mum. As with any electromechanical equipment, however, periodic
inspection and adjustment will assure optimum performance. As the
friction disc wears, the magnet gap will increase. The magnet gap
should be check periodically and adjusted when necessary.

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 con-
tact 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.
10. Upon usage, the inside surfaces of the brake will contain fric-
tion material dust. This dust must be removed before servic-
ing or adjusting the brake. It is important to avoid dispersing
dust into the air or inhaling it, as this may be dangerous to
your health. To avoid dispersing the dust into the air, DO NOT
blow the dust off the brake. Remove dust with a vacuum.
Avoid breathing dust.
Wear a respirator if dust becomes airborne.
