Motors installed outdoors or in the vertical position require the
use of additional shelter to protect them from water; for instance,
use of a drip cover.
To prevent accidents, ensure that the grounding connection has
been performed according to the applicable standards and that
the shaft key has been well-fixed fastened before the motor is
started.
Connect the motor properly to the power supply by means of safe
and permanent contacts, always considering the data informed
on the nameplate, such as rated voltage, wiring diagram, etc.
When using terminals, all wires that form the stranded cable must
be fastened inside the sleeve. The insulation of the accessories
cables must be kept up to 1 mm from the connector connection
point.
For power cables and grounding system connections and terminal box
assembly, the tightening torques indicated on Tables 1 and 2 must be
respected.

If any defect or abnormal occurrence is detected during
machine operation, the customer must immediately notify WEG
in writing about the occurred defect, and make the product
available for WEG or its Authorized Service Center for the period
required to identify the cause of the defect, check the warranty
coverage, and perform the proper repairs.
In order for the warranty to be valid, the customer must be sure
to follow the requirements of WEG technical documents,
especially those set out in the product Installation, Operation
and Maintenance Manual, as well as the applicable standards
and regulations in force in each country.
Defects arising from the inappropriate or negligent use,
operation, and/or installation of the equipment, non-execution
