Note 3. Installation
• Barrier must be installed in an enclosure that
meets the requirements of ANSI/ISA S82.01.
• Control equipment connected to barrier must
not use or generate more than 250 V rms or
V dc.
• Installation should be in accordance with
ANSI/ISA RP12.6 “Installation of Intrinsically
Safe Systems for Hazardous (Classied)
Locations” and the National Electric Code
(ANSI/NFPA 70).
• The conguration of associated apparatus
must be FMRC Approved.
• Dust-tight conduit seal must be used when
installed in a Class II, III, Group E, F and G
environments.
• Associated apparatus manufacturer’s
installation drawing must be followed when
installing this apparatus.
• The maximum power delivered from the
barrier must not exceed 1 W.
• Note a warning label worded
“SUBSTITUTION OF COMPONENTS MAY
IMPAIR INTRINSIC SAFETY,” and “INSTALL
IN ACCORDANCE WITH DOC. No. IFM022-
A12”
Note 4. Maintenance and Repair
• The instrument modication or parts
replacement by other than authorized
representative of Yokogawa Electric
Corporation is prohibited and will void
Factory Mutual Intrinsically safe and
Nonincendive Approval.
