Driven Shaft/Surface
A rotating component of a mechanical system which is driven by a
drive shaft. Typically connected to the drive shaft via a clutch to
allow the driven shaft/surface to be engaged when needed. The
driven shaft/surface refers to the component directly connected to
the drive shaft. See Load for a broader term for all parts of the
system driven by the motor.
Dry running
Operation in dry environments with no danger of dripping or
splashing liquids.
EC Declaration of
Conformity
Declaration that the device conforms to EU standards of safety.
Equipotential Bonding
A practice of intentionally electrically connecting all exposed metal
items not designed to carry electricity in a room as protection from
electric shock.
Flange
A plate integrated on the magnet housing used to mount the
brake magnet.
Friction Surface
The surface of the armature and magnet that contact during brake
engagement.
KEB Automation KG
Parent company of KEB America, Inc. Also referred to as KEB.
Load
The components of a mechanical system driven by a motor. The
load refers to the entire system powered by the motor. See Driven
Shaft/Surface for the individual component connected directly to
the drive shaft.
Machine Manufacturer
The manufacturer of the application in which the COMBINORM
brake is installed. Not KEB America, Inc.
Magnet
The component of the brake which contains the magnetic
components.
Mounting Surface
A surface to which the COMBINORM device is physically
attached. The COMBINROM is typically attached to the mounting
surface with the recommended socket-head screws, but other
fastening methods may be used as appropriate to the application.
NEC
US National Electric Code. Safety standard for electrical
installations used in the United States.

Recommended tightening
torque
The torque required to fully screw a socket head screw into a
mounting surface. The recommended tightening torque depends
on the type of screw used as well as the material, thread depth
and locking components (if any) used in the mounting surface.
Refer to the machine manufacturer for details on recommended
tightening torques for specific mounting surfaces.
Run-out
An inaccuracy of rotating mechanical systems whereby the shaft
does not rotate precisely in line with the main axis. Always
present but must be minimized.
Specified Application
The specific application for which the COMBINORM device was
ordered, is usually (but not always) the same as the Application in
which the device is being used.
