2.1.
Unauthorised usage
In particular, the following uses of motors are prohibited and can lead to machinery failure:
•
Operating the motor with imbalance, for example, caused by dust deposits or icing.
•
Resonance operation, operation with strong vibrations, transmitted from the environment to
the motor. Periodic shock impacts only up to 1G are permissible. For the higher shock loads
contact SEVA-tec GmbH.
•
Painting of the motors (if not explicitly approved by SEVA-tec GmbH).
•
Release connections, for example, screws during operation.
•
Opening the terminal box during operation.
•
Operating the motors near combustible materials or components.
•
Operating the motors in an explosive atmosphere.
•
Operation with fully or partially dismantled or manipulated devices.
2.2.
EU Motor regulation VO (EG) No. 640 / 2009
Since June 2011 the European Commission’s Regulation (EC) No. 640 / 2009 for electric motors has
come into force.
The regulation governs the eco-design requirements for 2-, 4- und 6-pole low-
voltage three-phase asynchronous motors in the power range 0.75 kW to 375 kW.
From 1. January 2017 all motors with a rated power of 0,75 – 375 kW shall achieve at least the
efficiency level IE3, defined in point 1 of the Annex I or the level of efficiency IE2 defined in point 1 of
the Annex I and be equipped with a variable speed drive.
The regulation hereby allows the user to use either an IE3 motor (for fixed or variable speed), or an
IE2 motor in conjunction with a speed controller.
The user is responsible for compliance with the
requirements of the EU regulation.
3. Transport und storage
Keep the motors safe against mechanical damage and only in closed dry rooms. In case of short-term
storage in an open air area the motors must be protected against harmful environmental influences.
Motors must not be transported and stored on the fan cover. For transport the eye bolts of motors
must be used with suitable lifting devices. The eye bolts are only intended for lifting the motor without
additional attachments such as base plates, gear boxes etc. If the eye bolt is removed after installation,
the openings must be permanently closed according to the type of protection.
For longer storage periods, a low vibration environment should be ensured to avoid bearing damage.
After a storage period or downtime period of more than 12 months, a check of the grease state of all
lubricated parts, such as bearings and shaft seal rings, must be carried out before commissioning and,
if necessary, the grease must be replaced.
4. Installation and assembly
The following points must be observed during installation and assembly:
Caution: for longer storage or
downtime periods a check of
bearings and oil seals must be
conducted before commissioning.
