2. INITIAL RECOMMENDATIONS

Motors for hazardous areas are specially designed to meet the government regulations regarding the
environment in which they are installed. Misapplication, incorrect connection or other changes although
small, may jeopardize product reliability.
Electric motors have energized circuits, exposed rotating parts and hot surfaces that may cause serious injury
to people during normal operation. Therefore, it is recommended that transportation, storage, installation,
operation and maintenance services are always performed by qualified personnel.
Also the applicable procedures and relevant standards of the country where the machine will be installed must
be considered.
Noncompliance with the recommended procedures in this manual may cause severe personal injuries and/or
substantial property damage and may void the product warranty.
For practical reasons, it is not possible to include in this Manual detailed information that covers all construction
variables nor covering all possible assembly, operation or maintenance alternatives.
This Manual contains only the required information that allows qualified and trained personnel to carry out their
services. The product images are shown for illustrative purpose only and the type of protection is not represented.
The type of protection and the Equipment Protection Level (EPL) indicated on the motor nameplate must be
respected considering the explosive atmosphere where the motor will be installed.
Components added to the motor by the user, such as cable-glands, threaded plugs, encoder, etc. must meet the
type of protection, the Equipment Protection Level (EPL) in accordance with the standards indicated on the
product certificate.
The symbol "X" added to the certificate number, informed on the motor nameplate, denotes that motor requires
special conditions for installation, use and/or maintenance, as described in the certificate.
Failure to follow these requirements may affect the product and installation safety.
