2 Safety instructions
2.1 Personnel responsible for safety
Operator
❚An operator is any natural or legal person who uses the CBC or on whose behalf the CBC is used.
❚The operator or his safety personnel must ensure
- that all relevant regulations, notes and laws will be maintained,
- that only qualified personnel work on and with the drive system,
- that the Operating Instructions will be available to the personnel working on and with the brake at
all times,
- that unqualified personnel will not be allowed to work on or with the CBC.
Qualified personnel
Qualified personnel refers to those who – due to their training, experience, instruction and knowledge of rel-
evant standards and regulations, accident prevention regulations and operating conditions related to the
safety of the facility – have been entitled by the person responsible for thesafety of the system to work on
and with the system and to recognize and avoid all possible dangers.
(Definition of qualified employees according to IEC 364)
Application as directed
❚Drive systems
- are intended for use in machinery and systems.
- must only be used for their intended and confirmed purposes.
- must only be operated under the ambient conditions prescribed in these Operating Instructions.
- must not be operated beyond their corresponding power limits.
Any other use is considered improper!
2.2 General safety instructions
❚Wemakenoclaimtocompletenessconcerningthesesafetynotices.PleasecontactyourlocalINTORQ
representative if you have questions or problems.
❚The clutch-brake combination met the state of the art at the time of delivery and is generally safe to op-
erate.
❚Theclutch-brakecombinationendangerspersons,the clutch-brakecombinationitself and other proper-
ties of the user if
- non-qualified personnel work on or with the CBC.
- the CBC is used inappropriately.

Safety instructions
INTORQ | BA 14.0176 | 06/2017 10
❚The clutch brake combination (CBC) must be designed so that it carries out its functions properly and
doesnotcausedangerforpersonsifitisinstalledcorrectlyandusedasintendedinerror-freeoperation.
This also applies to the interaction with the overall system.
❚Do not operate the CBC unless it is in perfect condition.
❚RetrofittingsorchangestotheCBCareprohibited.TheyalwaysrequirepriorconsultationwithINTORQ
GmbH & Co. KG.
❚The friction lining and the friction surfaces must never contact oil or grease since even small amounts
reduce the braking torque considerably.
❚The brake torque will usually not be influenced if the brake is used under the environmental conditions
that apply toIP40. Because of the numerous possibilities of using the brake, it is however necessary to
check the functionality of all mechanical components under the corresponding operating conditions.
Higher protection degrees are available on request.
2.3 Application range of the CBC
❚No potentially explosive or aggressive atmosphere.
❚Humidity, no restrictions.
❚Ambient temperature -20°C to +40°C.
❚With high humidity and low temperatures
- Take measures to protect the armature plate and rotor from freezing.
❚Protect the electrical connections against any contact or touching.

3.1 Product description
Abb. 1 Design of the CBC
3.1.1 General information
The type14.800 CBCs are electromagnetic encased units with asbestos-free friction linings.
TheCBCsareusedforengaginganddisengagingshaftsinalltypesofmechanicalengineeringapplications.
Themodularsystemthatisusedallowsformanyvariationsandmountingoptions.Clutchesandbrakesfrom
the 14.105/115 series transmit the speed or brake torque by means of friction whenever DC voltage is ap-
plied.
In addition to the splined armature that permits high switching frequencies, a backlash-free torque transmis-
sion is ensured by the diaphragm armature. A low brake torque remains present even if the voltage is dis-
connected.
As the drive runs continuously with the clutch motor, the energy from the upstream drive can be used to ac-
celerated the output.

The transition from a state free ofbraking torque to one of steady braking torque is not immediate. The en-
gagement times apply to switching on the DC side with a spark suppressor at induction voltages of approx.
5to10timesoftheratedvoltage.WhenswitchingontheACside,thedisengagementtimesincreaseapprox.
by a factor of 6 compared to switching on the DC side. The diagram shows the delay time for engagement
"t11", the rise time of the brake torque "t12", the engagement time "t1= t11 + t12" and the disengagement time
"t2".

tion.

3.4 Switching energy / operating frequency
Abb. 4 Friction work as a function of the switching frequency for the INTORQ 14.800
The permissible switching frequency "Shzul" depends on theswitching energy "Q". At apre-set switching fre-
quency "Sh", the permissible amount of switching energy is "Qzul".
With high speeds of rotation and switching energy, the wear increases strongly, because very high temper-
atures occur at the friction surfaces for a short time.

4 Mechanical installation
Important notes
4.1 Assembly
4.1.1 Preparing the installation
1. Unpack clutch-brake combination.
2. Check for completeness.
3. Check whether the name plate data correspond to the accompanying papers.
4.2 Installation
The drives can be used in either a horizontal or vertical mounting position.
DANGER
There is a risk of injury by electrical shock!
❚The clutch-brake combination must only be installed when no voltage is applied!
NOTICE
In any mounting position, ensure that no liquid or foreign particles ingress into the housing!
NOTICE
❚Avoid shocks onto shafts and hollow shafts!
❚Grease shafts and hollow shafts only lightly!
❚The friction linings of rotor and brake must be kept free of grease and oil!
NOTICE
A vertical mounting position makes motor and gearbox mounting easier.
