APPENDIX 2
FM Approval for use in the USA and
cFM Approval for use in Canada
A2.0 Factory Mutual Approval
For installations in the USA and Canada, a version
of the BA444DF-P is available with FM and cFM
intrinsic safety and nonincendive approval, project
identifications 3027031 and 3027031C. Copies of
the Certificates of Compliance are available from
BEKA associates sales office and www.beka.co.uk
The FM and cFM Approved version is identical to
the ATEX version except the three M20 x 1,5
tapped cable entries are replaced by three plain
unthreaded 22.25mm diameter entries. Approved
hubs and glands are listed in note 6 of Intrinsically
Safe Control Drawing CI410-12 and note 5 of
Nonincendive Control Drawing CI410-13. The
certification label on the FM and cFM Approved
version includes ATEX gas certification information
so that the BA444DF-P PROFIBUS PA indicator
may be used in systems covered by either
authority.
A2.1 Intrinsic safety approval
The BA444DF-P is approved to FM Class 3610
intrinsic safety standard for use in indoor and
outdoor hazardous (classified) locations.
Installations must comply with BEKA associates
Control Drawing CI410-12, which is attached to
this Appendix, ANSI/ISA RP12.06.01 ‘Installation of
Intrinsically Safe Systems for Hazardous
(Classified) Locations’ and with the National
Electrical Code ANSI/NFPA70.
The BA444DF-P has a T4 rating at ambient
temperatures up to +70
o
C and may be used with
the following gases and dusts:
Intrinsic Safety
Division 1 or 2
Class I Group A & B
Group C
Group D
Class II Group E, F & G
Class III
Zone 0, 1 or 2
Class 1 Group IIC
Group IIB
Group IIA
Canadian installations must comply with the
Canadian Electrical Code C22.2 and with BEKA
associates Control Drawing CI410-12, which is
attached to this Appendix.
The FM and cFM entity parameters are identical to
the ATEX parameters and, like the ATEX
certification, confirm that the BA444DF-P complies
with the FISCO Field Device requirements
specified in IEC60079-27. The intrinsically safe
system shown in Fig 1 of this manual may
therefore be used for installations in the USA and
Canada, providing the fieldbus power supply,
terminators, Zener barriers and galvanic isolators
are FM Approved for US installations and cFM or
CSA Approved for Canadian installations. All
installations must comply with BEKA associates
Control Drawing CI410-12 .
FM and cFM Approvals also allows the BA444DF-
P to be connected to non-FISCO systems using
the entity concept – see section 3.2 of this manual.
A2.2 Nonincendive approval
The BA444DF-P is FM Class 3611 nonincendive
approved allowing it to be installed in Division 2
indoor and outdoor hazardous (classified) locations
without the need for Zener barriers or galvanic
isolators. US installations must comply with the
BEKA associates Control Drawing CI410-13, which
is attached to this Appendix, and with the National
Electrical Code ANSI/NFPA70.
Canadian nonincendive installations must comply
with the Canadian Electrical Code C22.2 and with
BEKA associates Control Drawing CI410-13, which
is attached to this Appendix.
The FM and cFM Nonincendive Approvals also
allow the BA444DF-P PROFIBUS PA indicator to
be connected to any appropriately certified FNICO
compliant fieldbus segment.
The BA444DF-P has a T4 rating at ambient
temperatures up to +70ºC and may be used with
the following gases and dusts:
Nonincendive
Division 2
Class I Group A & B
Group C
Group D
Class II Groups E, F & G
Class III
