11.2 Ex Safety aspects and IP Protection
(North America)
11.2.1 Applicable standards
According to FM Approvals Standards which can assure
compliance with Essential Safety Requirements.
FM 3600: Electrical Equipment for use in Hazardous
(Classified) Locations, General Requirements.
FM 3610: Intrinsically Safe Apparatus and Associated
Apparatus for Use in Class I, II, III, Division 1,
and Class I, Zone 0 & 1 Hazardous (Classified)
Locations.
FM 3611: Nonincendive Electrical Equipment for Use in
Class I and II, Division 2 and Class III Division 1
and 2 Hazardous (Classified) Locations.
FM 3615: Explosionproof Electrical Equipment.
FM 3810: Electrical and Electronic Test, Measuring and
Process Control Equipment.
NEMA 250: Enclosure for Electrical Equipment (1000 Volts
Maximum).
11.2.2 Classifications
The 2600T Series pressure transmitters have been certified by
FM Approvals for the following Class, Divisions and Gas
groups, hazardous classified locations, temperature class and
types of protection.
— Explosionproof (US) for Class I, Division 1, Groups A, B, C
and D, hazardous (classified) locations.
— Explosionproof (Canada) for Class I, Division 1, Groups B,
C and D, hazardous (classified) locations.
— Dust Ignition proof for Class II, III Division 1, Groups E, F
and G, hazardous (classified) locations.
— Suitable for Class II, III, Division 2, Groups F and G,
hazardous (classified) locations.
— NonIncendive for Class I, Division 2, Groups A, B, C and
D, in accordance with Nonincendive field wiring
requirements for hazardous (classified) locations.
— Intrinsically Safe for use in Class I, II and III, Division 1,
Groups A, B, C, D, E, F, and G in accordance with Entity
requirements for hazardous (classified) locations.
— Temperature class T4 to T6 (dependent on the maximum
input current and the maximum ambient temperature).
— Ambient Temperature range -40°C to +85°C (dependent
on the maximum input current and the maximum
temperature class).
— Electrical Supply range Minimum 10.5 Volts, Maximum 42
Volts (dependent on the type of protection, maximum
ambient temperature, maximum temperature class and
communication protocol).
— Type 4X applications Indoors/Outdoors.
For a correct installation in field of 2600T Series pressure
transmitters please see the related control drawing.
Note that the associated apparatus must be FM approved.
