2 Safety instructions
2.1 General safety instructions
❚Never operate INTORQ components when you notice they are damaged.
❚Never make any technical changes to INTORQ components.
❚Never operate INTORQ components when they are incompletely mounted or incompletely connected.
❚Never operate INTORQ components without their required covers.
❚Use only accessories that have been approved by INTORQ.
❚Use only original spare parts from the manufacturer.
Keep in mind the following during operations:
❚Depending on the degree of protection, INTORQ components may have both live (voltage carrying),
moving and rotating parts. Such components require the appropriate safety mechanisms.
❚Surfaces can become hot during operation. Take the appropriate safety measures (to ensure contact/
touch protection).
❚Follow all specifications and information found in the Operating Instructions and the corresponding doc-
umentation. These must be followed to maintain safe, trouble-free operations and to achieve the speci-
fied product characteristics.
❚The installation, maintenance and operation of INTORQ components may only be carried out by quali-
fied personnel. According to IEC 60364 and CENELEC HD 384, skilled personnel must be qualified in
the following areas:
- Familiarityandexperiencewiththeinstallation,assembly,commissioningandoperationoftheprod-
uct.
- Specialist qualifications for the specific field of activity.
- Skilled personnel must know and apply all regulations for the prevention of accidents, directives,
and laws relevant on site.

ThebasicmoduleEisadjustable(thebrakingtorquecanbereducedusingtheadjustmentring).Thespecial
feature for basic module L (with an identical design) is the more durable materials (torque support, guide
pins, toothed intermediate ring, friction lining and gear teeth). The double-brake version is especially useful
in redundant braking applications.

3.2.4 Basic module N, doubled design
Fig. 3 Design of the INTORQ BFK458 spring-applied brake: Basic module N, doubled design with intermediate flange
Function
The spring-applied brake is a single-disk brake with two friction surfaces. The braking torque is generated
by several pressure springs with friction locking. The braking circuits are released electromagnetically. Dur-
ingthebrakingprocedure,thespring-appliedbrakeconvertskineticenergyintoheatenergy.Duetothestat-
ic braking torque, loads can be held at standstill. Emergency braking is possible at high speed of rotation.
Note that the wear will increase when there is emergency braking with high switching energy.
Braking and release
During the braking procedure, the inner and outer springs use the armature plate to press the rotor (which
can be shifted axiallyon the hub) against the friction surface. The asbestos-free friction linings ensure high
brakingtorqueandlowwear.Thebrakingtorqueistransmittedbetweenthehubandtherotorviagearteeth.

3.3 Optional configuration
3.3.1 Manual release (optional)
Totemporarilyreleasethebrakewhenthereisnoelectricityavailable,amanualreleasefunctionisavailable
as an option. The manual release can be retrofitted (for installation refer to 41).
3.3.2 Optional microswitch
Themicro-switch is usedfor thereleasecheckorfor wearmonitoring.Theuser is responsiblefor arranging
the electrical connection for this optional microswitch.
❚Usage for the (air) release check: The motor will start only after the brake has been released. This ena-
bles the microswitch to monitor for errors (e.g. when the motor does not start because of a defective
rectifier, if there are broken connecting cables, defective coils, or an excessive air gap).
❚Usage for monitoring wear: The brake and motor are supplied with no power when the air gap is too
large.
3.3.3 Optional encapsulated design
This design not only prevents the penetration of spray water and dust, but also the spreading of abrasion
particles outside the brake. This is achieved by the following encapsulation:
❚A cover ring over the armature plate and rotor.
❚Cover plate
❚Shaft seal (can be supplied for continuous shaft).
3.3.4 Optional CCV
The Cold Climate Version (CCV) allows the brake to be operated at lower ambient temperatures.

❚Degree of protection:
- The brake is designed for operation under the environmental conditions that apply to IP54 protec-
tion.Becauseof thenumerouspossibilitiesofusingthebrake,it isstillnecessaryto checkthe func-
tionality of all mechanical components under the corresponding operating conditions.

4.1 Brake torque reduction
For basic module E, the brake torque can be reduced using the adjustment ring in the stator. The adjustment
ring can be unscrewed to the maximum protrusion of "h
