Introduction; Declaration Of Conformity; Validity; Conformity - ABB M2A Manual De Instalación E Usuario

1. 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 official regulations concerning the risk of
explosion. The reliability of these motors may be
impaired if they are used improperly, badly connect-
ed, 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.

1.2 Validity

(Additional information may be required by ABB when
deciding on the suitability of certain motor types used in
special applications or with special design modifications.)
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 tempera-
tures exceeding these limits, please contact ABB.

1.3 Conformity

As well as conforming to the standards relating to me-
chanical and electrical characteristics, motors designed for
explosive atmospheres must also conform to one or more
of the following European or IEC-standards for the protec-
tion type in question:
EN 60079-0 (2004);
IEC 60079-0 (2004)
EN 60079-1 (2004);
IEC 60079-1 (2003)
EN 60079-7 (2003),
IEC 60079-7 (2001)
EN 60079-15 (2003),
IEC 60079-15 (2001),
EN60079-15 (2005),
IEC 60079-15 (2005)
prEN 61241-0 (2005);
IEC 61241-0 (2004)
EN 61241-1 (2004);
IEC 61241-1 (2004)
Note: the standards, according to which motors are
certified, are listed in the appropriate certificate.
ABB LV motors (valid only for Group II) can be installed in
areas corresponding to the following markings:
Zone Category or Marking
1 Category 2 or Ex d, Ex de, Ex e
2 Category 3 or Ex nA
21 Category 2 or DIP, IP 65 or Ex tD A21
22 Category 3 or DIP, IP 55 (non-conductive dust),
or Ex tD A22
According to the EN 500XX series, certified motors have
EEx markings instead of Ex.
