Page 25: Mounting The Brake
MOUNTING 4.2 Mounting the brake ATTENTION If no suitable friction surface is available. ► Install the optional flange (4) on the motor bearing assembly. Step 1: Installing the hub Install the hub (2) on the motor shaft, then secure the hub on the motor shaft axially. The hub and the linings must not be dam- aged! Make sure that the hub cannot run against the second friction surface. - Page 26 MOUNTING Step 2: Mounting the lining Slide the lining (3) onto the hub. While doing so, be careful not to damage the lining by misaligned or tilted position- ing. The lining must be easily movable on the hub! Step 3: Mounting the magnetic system Slide the fully assembled magnetic sys- tem (1) over the hub and the lining.

ELEcTrIcAL cONNEcTION NOTICE connection at inverter operation. ► Rectifiers or power boxes are destroyed when operated at drive converters. ► Rectifiers or power boxes may only be connected directly to the mains. Influence on the connection time! The brake can be switched off on the DC side or on the AC side. Switching off on the DC side reduces the connection time, i.e. the period of time until the torque is reached to decelerate. -
Page 32: Dc Side Switching
ELEcTrIcAL cONNEcTION 5.1.2 Dc Side Switching Switching occurs between rectifier and brake. KEB rectifiers and power boxes are pro- tected against voltage peaks occurring during switching. ► Not suitable for inverter operation since the powerbox or rectifier would be destroyed. Figure 12: Connection for DC side switching 5.1.3 Dc and Ac current switching ► Inverter operation possible because the powerbox or rectifier is supplied by the mains. -

MAINTENANcE AND SErvIcE 9 Maintenance and Service • Observe the general safety instructions. • The brake must not be under voltage during maintenance and repair work! • Protect electrical and electronic components from splash water. 9.1 Maintenance intervals Due to the design, the brake COMBISTOP Type 28 can only be checked when it is removed. -
Page 37: Check Air Gap
MAINTENANcE AND SErvIcE 9.2.2 check air gap The brakes are delivered ex works with pre-set air gap X (nominal air gap) ready for installation. As a result of wear, the air gap increases. To ensure proper functioning, the air gap (distance between magnet housing on lining) needs to be checked in regular intervals in energized state with dial gauge (measuring bridge). -
