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 enclo-

sure 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 minimum.

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,

INSTALLATION

(See Figures 3, 5 & 6, Tables 1, 2 & 3)

1. Remove hub (1) from brake and position on motor shaft with key

according to dimension "N". Stamped part number on hub should

face away from motor. Tighten hub set screws with 12 lb. ft.

torque.

2. Remove cover screws (24) and cover (23), plus gasket (28) on

enclosed and severe duty models.

3. Place brake on motor, guiding discs on hub.

4. Bolt brake to motor "C" face with four 1/2 inch socket head cap
