Installation

5 Installation
The COMBISTOP type 38 brake is designed to be mounted on an existing motor or
mounting surface over the drive shaft. The COMBISTOP uses the mounting surface as a
friction surface for functioning of the brake. As such, the mounting surface must be rigidly
fixed and incapable of angular motion. Friction surfaces made of cast iron or steel are
best suited for the COMBISTOP type 38. If a suitable friction surface is not available, an
optional flange or friction disk can be installed between the COMBISTOP and the
mounting surface.

5.1 Before You Begin

Fill out the following pre-install checklist before you being installing the COMBISTOP
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 teeth of the hub and friction lining are not damaged.
☐
Ensure the friction lining is easily moveable on the hub.
☐
Ensure the mounting bolt circle and surface meet the installation requirements for
☐
eccentricity and angular deviation.
