Check of the external condition of the product (check of insulation, transport
damage, protective gas filling,...).
Check that all electrical work has been carried out in accordance with the
standards (e.g. protective earth, insulation, shielding, covers). If necessary,
an earthing connection must be provided.
The area around the product in which the start-up is carried out must be
marked and secured against the access of unauthorised persons. Sufficient
lighting of the working area must be ensured to prevent personal injury and
material damage.
Operating and functional capability of the machine room equipment (suction
and ventilation).
Personal protection gear (work clothing, work boots, gloves) must be worn
during all work on the system. There is a danger of impacts and tripping
against protruding parts (e.g. valve caps). There is also a danger of cut
wounds on sharp edges and rough surfaces. All activities must, therefore, be
carried out with particular attention.
Suitable hearing protection must be worn in order to protect against damage
to hearing or deafness.
Thermal hazards resulting in injury due to burns or freezing may occur on
contact with parts of the system which are at a very high or very low tempera-
ture. Personal protective equipment must be worn.
Suitable tools or special tools must be used.
The direction of rotation of the drive motor must be checked.
–
Before start-up, i. e. before you connect the voltage supply, check that the
coupling between the drive motor and compressor is disconnected. Other-
wise, the coupling intermediate piece must be removed in accordance with
the assembly instructions.
Both coupling hubs must be push back so that they cannot inadvertently
mesh during the rotation direction test. Check tight seating of the coupling
hubs on the shaft ends.
–
It is essential to ensure that the compressor drive motor cannot be started
inadvertently.
–
The required direction of rotation must be controlled in correspondence
with the rotational arrow at the compressor or the specifications in the
compressor documentation.
–
In "Manual" operation mode, the compressor drive motor is started com-
pletely and is then switched off.
–
Change the direction of rotation of the motor if this is not correct!
–
The electrical switchgear must then be secured again to prevent it from
being switched on inadvertently. Mount the coupling while following the
instructions of the separate documentation.
