Installation Instructions Mounting Introduction Note: For proper function, mount magnetic particle units horizontally. 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. Mounting dimensions for the PRB-H can be found on page 6 & 7. Pre-Mounting Note: Unit performance can be affected by prolonged exposure to humid environments. Please store in a dry location.
Electrical Connections To avoid injury (or even death), always make certain all power is off before attempting to install or service the control or any electrical equipment. Maintenance Warner Electric Magnetic Particle brakes operate on DC voltage. Warner Electric offers a full line of AC powered controls to meet the needs of almost every application. The service and installation instructions included with each Warner Electric control show the proper electrical connections for the brake.
