4.1

General information for safety

The safety aspects to be observed for operating the
equipment are shown in the chapter on "Safety".
The equipment has been developed and manufac-
tured according to the currently applicable state of
the art and is reliable in operation. It has been tested
and left the factory in a technically faultless safe con-
dition.
In order to maintain this condition for the operation
time, the details of the project documentation and
certificates must be observed and complied with.
When operating the equipment, at least the general
safety regulations and the provisions and guidelines
referred to in this documentation must be observed.
Only compliance with all provisions and guidelines
will enable optimum protection of the personnel as
well as dangers to the environment and the safe and
smooth operation of the equipment.
4.2

Behaviour in the case of emergency

Hint!
Familiarise yourselves with the local
evacuation plan before beginning the
work.
Should an emergency situation arise despite adher-
ing to the safety regulations, the package/chiller
must be shut down immediately and isolated from
the electrical mains.
The mains cable must be blocked in such a way it is
not possible to restart the unit accidentally and
marked as such.
The operator of the complete system has to take
care that an isolation device, e.g. a mains switch with
appropriate contact rating and an integrated indica-
tor, is pre-installed in the mains cabling on site.
A separate mains cable/feed cable must be laid for
the operation of the package/chiller.
The mains cable/feed cable is to be specially protec-
ted and provided with an emergency stop switch.

Possible residual hazards

Warning!
Despite careful design of the machine
and implementation of all the safety-
relevant regulations, further risks for
persons and machine during all life
phases of the package/chiller cannot
be fully ruled out. The additional safety
instructions in the individual chapters
of this manual must therefore be care-
fully observed!
Residual risks that were ascertained during the risk
assessment carried out for the product according to
safety standard EN ISO 14121 - Safety of Machines
- are:
– mechanical hazards due to sharp sheet metal
edges and projecting parts,
– electrical hazards as a result of inadvertently
coming in contact with terminals and cables,
– thermal hazards as a result of inadvertently com-
ing in contact with heat exchangers and pipes,
– exposure to noise,
–
hazards caused by vibration due to improper
installation,
–
hazards due to working materials and other
materials in case of allergies orthe like,
–
neglect of ergonomic principles,
– combinations of various hazards,
– unexpected start-up, unexpected rotation in case
of incorrect electrical connections or defects,
– shut-down, emergency stop when defects are
detected,
– changes to the rotational speed,
– power failure,
– failure of the control circuit or control loop,
–
incorrect assembly,
– fracture during operation,
– operating media or objects getting thrown out,
– loss of stability and
– personnel slipping, tripping or falling.
