++
ATTENTION!
Any service on the internal parts of the motor must be performed by qualified personnel only, since, due to the
attraction between metallic parts caused by the magnets, risk of accident is present both in the assembly and
disassembly of the motor.
3. SHIPMENT, STORAGE AND HANDLING
Check the conditions of the motor immediately upon receipt. Where any damage is noticed, this must be reported in writing
to the transportation company, and immediately communicated to the insurance company and to WEG. In this case, no
installation job can be started before the detected problem has been solved.
Check if the nameplate data matches the invoice data and the environmental conditions in which the motor will be installed.
If the motor is not immediately installed, it must be stored in a clean and dry room protected against dust, vibrations, gases
and corrosive agents, and with temperature between -25 ºC and 60 ºC and relative humidity not exceeding 60%.
If the motors are stored for more than two years, it is recommended to change the bearings, or to remove, wash, inspect
and relubricate them before the motor is started.
DANGER!
g
Always handle the motor carefully in order to prevent personal injuries and impacts that could damage the
bearings.
When available, do not lift and/or carry the product holding by the input cables.
When available, use only the eyebolts to lift the motor. However, these eyebolts are designed for the motor weight
only. Thus, never use these eyebolts to lift the motor with additional loads coupled to it. For multimounting motors (with
removable feet/ base), the eyebolts must be positioned according to the motor mounting position so that the lifting angle
is vertically aligned (lifting at 0°).
Additional information regarding the maximum allowable angle-of-inclination is indicated in the general manual
available on the website www.weg.net.
