1. Information on Operating and Assembly Instructions

1.1 Validity

These operating and assembly instruction (in accordance with their title) are generally valid only

for the Getriebebau NORD design of the electromagnetically released spring-applied
brakes FDB 08 to FDB 40 of M/s. PRECIMA Magnettechnik GmbH. Moreover, they are a

necessary element of every brake delivery and generally only valid for such simultaneously
delivered brakes. The operating and assembly instruction will even continue to be valid for such
brakes, if a later version of the instructions exists, unless M/s. PRECIMA expressly declares to
the customer that the later version replaces the older one.

In individual cases, the above mentioned principles may be deviated from (e.g. in case of
special designs or repeated deliveries). In any case, an indicative or supplementing information
of M/s. PRECIMA will be required.

1.2 Purpose and Use

These operating and assembly instructions are to contribute to a safe and proper
assembly and operation of the spring-applied brake.

In order to meet this requirement and purpose, all the persons dealing with the assembly and

the operation of the brake (qualified according to 2.1.2) have to completely and thoroughly
read these instructions before carrying out their respective activities (assembly, commissioning,
operation, maintenance, etc.). Furthermore, said persons of course have to observe and
implement the given instructions when carrying out their respective activities. The

instructions themselves must be accessible any time (even after completion of the respective
activity) and within short time in a clean, complete and well legible condition.

Despite careful and thorough elaboration of the instructions, mistakes, defects and
incompleteness in the operating and assembly instructions cannot be excluded. For this reason,
please consult M/s. PRECIMA if in doubt. Other technical questions, notes and suggestions for
improvement can also be directed to the following address:

1.3 Terms and Identification of Notices

Important notices in Chapter 4 (Assembly), Chapter 5 (Operation) and Chapter 6 (Disassembly /

Exchange) referring to technical security as well as to industrial safety are particularly

highlighted by the following signal words:

Data sheet = Technical data sheet

End plate = Motor end plate = end plate of an electric motor
Dimension sheet = Dimension drawing
PRECIMA = M/s. PRECIMA = PRECIMA Magnettechnik GmbH, Bückeburg
Shaft = Motor shaft = shaft of an electric motor

In the scope of these operating and assembly instructions, the spring-applied brake is

observed in order to exclude a hazard to persons.

ÎAttention! Refers to safety measures which must absolutely be followed in order to

avoid brake failures.

ÎStop! Refers to instructions that have to be particularly observed when carrying

out the work described.

In order to simplify the text of these operating and assembly instructions, certain longer and
complicated terms are replaced by shorter ones which will have the following meanings in the
scope of these instructions:

Instructions = Operating and assembly instruction
Working brake = Brake which implements friction work in regular operation, i.e. performs a

braking function

Brake = Spring-applied brake = electromagnetically released spring-applied brake

Holding brake = Brake which does not

holds the load in position. In case of an emergency, however, it may also perform a braking
function.

considered to be a machine element to be connected to an electric motor since this
combination represents the most frequently used variant. Accordingly, certain designations

refer to said fact (motor shaft, motor end plate Î see above). However, this is no general
limitation of the validity of these instructions to such combinations - just as there is no
comparable limitation to the application of the spring-applied brake at all.

2. Conditions for Assembly and Operation

2.1 Persons

2.1.1 Operator

Operator is that natural person or entity using the spring-applied brake or instructing the spring­applied brake to be used. The operator and/or a person assigned by him must safeguard the

proper use according to 2.3 and the observance of relevant standards and provisions,
regulations and laws. In particular, he has to take care of the fact that only qualified personnel

according to 2.1.2 is entrusted with work at the brake.

2.1.2 Personnel
Personnel to carry out work at the brake must exclusively be qualified personnel who -

based upon their education, experience, instructions as well as knowledge concerning
relevant standards and provisions, accident prevention, regulations and operating
conditions - have been authorised by the person being responsible for safety, to carry
out the activities described in these instructions and who - when doing so - are in a
position to recognise possible risks early and to avoid them.

2.2 Product

2.2.1 Area of Application

The area of application of the brake is limited to plants and machines and is defined by the

general operating conditions stated in 2.2.4 as well as by the boundary conditions,
performance data and dimensions indicated in the dimension drawing and on the name plate
(lettering) of the brake (see: 3.1). Any deviation from these directives require a particular
agreement with PRECIMA. Particularly pay attention to the application as a working and an
application as a holding brake (definition: see 1.3).

2.2.2 Environment of Application

The environment of application of the spring-applied brake must be designed such that after its
proper assembly the brake may fulfil its function in perfect operation and will not pose any risk
for persons and material assets. Changes in the environment of application (e.g. at the machine
or plant which the brake is connected with) must only be carried out, if they have no influence
on the first mentioned condition.

2.2.3 State of Application

The permissible state of application of the brake includes the operationally perfect state of all
components (in case of worn parts: exchange in time) and the observance of the operating and
assembly requirements specified in these instructions as well as the omission of any retrofits,
changes or modification of the brake, unless authorised by PRECIMA. The latter also includes
the use of only original spare and exchange parts.

ÎAttention!

Friction surfaces and the friction lining should not under any circumstances be in
contact with oil or grease since already small quantities reduce the braking torque
considerably!

2.2.4 General Operating Conditions

Operating time: 100%
Ambient temperature: -10…+45°C

Should any of the above parameters be exceeded . M/s. PRECIMA should be contacted

for advice.

2.3 Proper Use

At the time of delivery, the spring-applied brake represents the state of the art technology, and

is generally considered to be reliable in operation. Only use it properly in order to avoid any risk
to persons and material assets.

The spring-applied brake is properly used, if qualified personnel (according to 2.1.2) by applying

the valid operating and assembly instructions (as per 1.1, according to 1.2) produces and
maintains a permissible state of application (according to 2.2.3) in an admissible environment

of application (according to 2.21).

The improper (inappropriate) use includes hazards which could not be completely taken
into account when designing and construction the brake and which are unforeseeable in
this sense.

2.4 Legal Aspects

2.4.1 Liability

On the basis of the information, data and directions given and of the illustrations and
descriptions included in these operating and assembly instructions, no claims for brakes outside
the area of application of these instructions (compare 1.1) may be submitted.

In general, an inappropriate use of the brake (compare 2.3) will exclude the liability of M/s.
PRECIMA.

2.4.2 Warranty

For the warranty terms refer to the General Terms of Sales and Delivery of M/s. PRECIMA
