Maintenance must be carried out by repair shops authorized

by WEG.

Repair shops and people without WEG’s authorization who

will perform any service or hazardous location motors will be
fully responsible for such service as well as for any
consequential damage.

THE INSTALLATION OF HAZARDOUS LOCATION

MOTORS MUST BE CARRIED OUT BY SKILLED

PEOPLE, AND THE THERMAL PROTECTION

MUST BE ALWAYS INSTALLED, EITHER  INSIDE

OR OUTSIDE THE MOTOR, OPERATING AT THE

RATED CURRENT.

ANY ELECTRICAL OR MECHANICAL

MODIFICATION MADE ON HAZARDOUS

LOCATION MOTORS WILL VOID THE

CERTIFICATION.

DO NOT REUSE DAMAGED OR WORN PARTS.

REPLACE THEM BY NEW ONES SUPPLIED BY

THE FACTORY.

When performing maintenance, installation or relubrication,

follow these instructions:

9

 Check if all components are free of edges, knocks or dirt.

9

 Make sure all parts are in perfect conditions.

9

 Lubricate the surfaces of the endshield fittings with protective

oil to make the assembly easier.

9

 Use only rubber hammer to fit the parts.

9
