Installation

5 Installation
The COMBINORM type 02 brake is designed to be mounted directly over the drive shaft
and affixed to a solid mounting surface. The mounting surface can be the motor itself or it
can be another solid structure.

5.1 Before You Begin

Fill out the following pre-install checklist before you begin installing the COMBINORM
brake.
☐
Fully read and understand all installation safety guidelines.
→
☐
Ensure the power supply meets the output requirements of the specific brake
being installed.
→
☐
Ensure the brake is not damaged or corroded, and that no foreign material
obstructs the air gap of the device. If corrosion is present thoroughly clean off
any corrosion with appropriate cleaning materials.
☐
Ensure the friction surfaces are free of grease or oil. Clean all friction surfaces
thoroughly before installing the brake. Use only sealed bearings when installing
the brake.
o
☐
Ensure the installation location is protected from humidity or aggressive
gasses/liquids which may degrade the friction surface.
☐
Ensure the installation location has adequate thermal protection to prevent the
brake from freezing. Freezing of the armature will result in a loss of braking
torque.
☐
Ensure the installation location is shielded against metal chips and other
magnetic particles which may be attracted to the magnet and cause loss of
braking torque.
☐
Ensure the mounting bolt circle and surface meet the installation requirements for
eccentricity and angular deviation.

5.2 Mounting Surface Requirements

The magnet and armature element must be precisely centered over the drive shaft before
mounting. The runout from the shaft to the mounting frame (A to
from the shaft to the edge of the magnet (A to
specified below or the brake may fail prematurely due to excessive wear and tear.

Never use aggressive fluids to clean the friction surfaces. KEB America
recommends using an alcohol based industrial brake cleaner.
