Introduction
This service manual provides information
required for installing, wiring, and maintaining
Warner Electric Magnetic Particle brakes.
Dimensions and specifications are also included.
The model covered in this service manual
includes PRB-H units with hollow bores. For
selection information, please refer to your
Warner Electric Tension Control Systems
Catalog.
Warner Electric Magnetic Particle brakes provide
smooth and controllable torque for a variety of
torque and tension control applications.
Extremely accurate tension control can be
achieved with an appropriate Warner Electric
tension control for electric brakes. They also
provide excellent performance in applications
where controlled stopping or deceleration is
desired. Quick deceleration is achieved by
applying full rated voltage. Lower voltage can be
applied for a gradual engagement.

Failure to follow these instructions may result in product damage, equipment damage, and serious or fatal injury to
personnel.
Make sure all power is turned
off to this equipment when installing, as
injury (or even death) may result from contact
with live wires or rotating shafts.

Installation Instructions
Introduction
The PRB-H brake mounts to a vertical surface
and the customer's shaft is secured in the input
hub of the unit. See Figure 2.
Pre-Mounting
Note: Unit performance can be affected by
prolonged exposure to humid environments.
Please store in a dry location.
Note: The equipment covered by this service
manual must be installed in accordance with
these instructions. Failure to do so may damage the equipment and void the warranty.
1. Remove your magnetic particle brake from its
shipping carton and inspect it thoroughly to
ensure that it has arrived in good condition.
When handling, please take care not to damage lead wires.
2. Check the input hub to make sure it turns
freely. The magnetic powder inside the unit
may settle due to shock and vibration caused
during shipping. If hub rotation is difficult,
turn the unit upside down and gently tap it to
loosen the powder.
3. Make sure the location chosen for mounting
will not expose the unit to water or oil as
these contaminants may affect unit performance. If the unit is mounted next to a gearbox, special care should be taken to prevent
oil from working its way into the unit.
4. If coupling(s) are used to connect to the drive
system, the mounting surface must properly
locate the housing to ensure that alignment is
within tolerance of the coupling(s).

PRB-H Installation Example
Mounting
Note: For proper function, mount magnetic
particle units horizontally.
Mounting dimensions for the PRB-H can be
found on page 6 & 7.
Step 1: Bolt Unit Into Place
Mount the unit to a vertical surface with customer supplied fasteners. PRB-H brake should
be mounted to a vertical surface. See Figure 2.
Step 2: Make Mechanical Connections
Slide the input shaft into the brake's bore. The
shaft should be supported from moving axially
using external bearings, snap rings, or locking
collars.
*Note: Shaded items are customer supplied.
