4.13.10 Storage for longer than two years
DANGER
Loss of type of protection "Ex d" as a result of incorrect storage or commissioning
This can result in death, serious injury, or material damage. An explosion can occur.
Only authorized technical personnel from the manufacturer or authorized by the manufacturer
or permitted to work on machines with type of protection "Ex d".
Preserving the machine before it is stored
● Protect the machine against moisture and humidity.
– Only store the machine in a dry and dust-free room. The relative humidity of the air must
be less than 60 %.
– Place desiccants (drying agents) in all of the terminal boxes.
– Place an adequate amount of desiccant in the machine itself.
– Wrap the machine in a barrier layer foil so that it is airtight, e.g. using composite
aluminum foil.
– Place a humidity meter inside the foil.
– Regularly check the air humidity within the foil using the humidity meter. If the relative
humidity within the packaging exceeds 50%, then replace the desiccant and the barrier
layer foil.
● Preserve parts of the motor shaft, journal bearings and enclosure that can possibly corrode
using Tectyl 506-EH from the Valvoline company.
● Close all journal bearing openings and check to ensure that they are correctly sealed.
When in storage – check at least every two years
● Replace the desiccant (moisture absorbing material) in the terminal boxes and in the journal
bearings.
● Open the journal bearings and check the anticorrosion protection applied to the shaft and
to the journal bearings. Apply Tectyl 506-EH from the Valvoline company with a dry film
thickness of 100 up to 150 µm to parts that are not correctly protected.
● Close all journal bearing openings and check to ensure that they are correctly sealed.
● Completely package the machine again, also see "Preserving the machine before it is
stored".
Preparing for commissioning and commissioning
Commissioning may only be carried out by appropriately trained personnel of the manufacturer
or those authorized by the manufacturer. Contact the Service Center regarding this topic.
