Introduction

NOTE!
These instructions must be followed to ensure safe
and proper installation, operation and maintenance of
the motor. They should be brought to the attention of
anyone who installs, operates or maintains the motor
or associated equipment. Ignoring these instructions
may invalidate all applicable warranties.
WARNING
Motors for hazardous areas are specially designed
to comply with offi cial regulations concerning the
risk of explosion. The reliability of these motors
may be impaired if they are used improperly, badly
connected, or altered in any way no matter how
minor.
Standards relating to the connection and use of
electrical apparatus in hazardous areas must be
taken into consideration, especially the national
standards for installation in the country where the
motors are being used. Only trained personnel
familiar with these standards should handle this
type of apparatus.

1.1 Declaration of Conformity

All ABB motors with a CE-mark on the rating plate
comply with the ATEX Directive 94/9/EC.

(Additional information may be required by ABB when
deciding on the suitability of certain motor types used in
special applications or with special design modifi ca-
tions.)
These instructions are valid for motors installed and
stored in ambient temperatures above – 20°C and
below +60°C. Check that the motor range in question is
suitable for this whole ambient temperature range. In
ambient temperatures exceeding these limits, please
contact ABB.
