2Safety
The purpose of these operating instructions is to enable users to:
use the coupling safely and correctly
maximize efficiency
ensure that care and maintenance are carried out correctly
For this reason, these operating instructions must be thoroughly read and
understood prior to work on and with the coupling.
WARNING
Injury and material damage can occur as a result of:
Failure to adhere to the safety and accident prevention regulations
valid at the relevant installation site
The safety and accident prevention regulations valid at the installation
site in question must be adhered to when performing any of the tasks
described in these operating instructions.
2.1 Safety remarks
In these operating instructions, safety remarks are indicated by a pictogram and
a signal word.
2.1.1 Signal words
The following signal words are used in the safety remarks:
DANGER
Denotes the immediate threat of danger.
If not prevented, fatal or extremely serious injuries can result.
WARNING
Denotes a potentially dangerous situation.
If not prevented, fatal or extremely serious injuries can result.
CAUTION
Denotes a potentially dangerous situation.
If not prevented, minor injuries and/damage to property may result.
IMPORTANT
Denotes application tips and particularly useful information. This is not
a signal word denoting a dangerous or damaging situation.

2.1.2 Pictograms
Possible pictograms in the safety precautions:
Warning of a hazardous area
Do not switch
Use protective gloves
Use protective goggles
2.2 Qualification of deployed personnel
All the work described in these operating instructions may only be performed by
authorized persons with adequate training and instruction.
WARNING
Injury and material damage can occur as a result of:
Work at the coupling which is not described in these instructions
Only carry out work which is described in these operating instructions.
2.3 Intended application
WARNING
Injury and material damage can occur as a result of:
Application not in compliance with the intended use
The couplings are intended exclusively for use in accordance with the
relevant design. They may only be used under the specified conditions.

WARNING
Injuries can occur as a result of:
Contact with rotating parts
Shield the coupling in accordance with the applicable accident
prevention regulations with an enclosure.
Exception:
The coupling is encased by the driving and driven units.
The scope of delivery provided by CENTA does not include a protective
enclosure.
This enclosure must fulfil the following criteria:
Provide protection against persons gaining access to rotating parts
Restrain any rotating parts which may be work loose
Guarantee sufficient ventilation for the coupling
This enclosure must be made of stable steel components. In order to ensure
adequate ventilation for the coupling, the enclosure must be fitted with regular
openings. For safety reasons, these openings must not exceed the dimensions
outlined in table 2-1.

Table 2-1 Shape and size of ventilation holes
The enclosures must be positioned a minimum of 15 mm distant from rotating
parts. The enclosure must be electrically conductive and be included in the
equipotential bonding.
Before commencing long-term operation, the plant must successfully complete a
test run.

2.4 Application not in compliance with the intended use
WARNING
Injury and material damage can occur as a result of:
Inadmissibly high torque
Inadmissibly high or low speeds
Exceeding the specified ambient temperature
Inadmissible ambient medium
Inadmissible coupling enclosure
Exceeding the admissible overall misalignment values
Only use the coupling for the specified application.
CENTA bears no liability for damage resulting from application not in compliance
with the intended use of the equipment.
Should there be a change of plant parameters, the coupling design must be
reviewed by CENTA (address see chapter 1).

3Delivery, transport, storage and disposal
3.1 Delivery
After delivery, the coupling:
must be checked for completeness and correctness of the delivery.
must be examined for possible transport damage (which must be reported
immediately to the carrier).
3.2 Transport
CAUTION
Injury and material damage can occur as a result of:
Incorrect transportation of couplings
Ensure that the coupling is correctly transported.
CAUTION
Material damage to coupling components can occur as a result
of:
Contact with sharp-edged objects
Protect coupling components for transportation.
Only hoist coupling components with nylon belts or ropes.
Always cushion parts when supporting them from below.
Following transportation damage:
Check the coupling carefully for damage.
Consult the manufacturer (Address see chapter 1).
3.3 Storage
CAUTION
Material damage to elastic elements and rubber parts can occur
as a result of:
Incorrect storage
These parts must be stored laid flat and so they cannot distort, and
protected from ozone, heat, light, moisture and solvents.
IMPORTANT
Rubber parts are marked where possible with their production date. From this date,
they may only be stored for a maximum of 5 years.
