3 Phase Brake Instructions

IP56 (NEMA 4) Housing

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 NEMA182C, 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.
