3. Flameproof joints are not intended for repair.
4. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that cause electrostatic build-up on
painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special code, contact the
manufacturer for more information.
7.10.2 IM Technical Regulation Customs Union TR CU 012/2011 (EAC)
Intrinsic Safety
Standards:
GOST 31610.0-2014, GOST 31610.11-2014
Markings:
[HART]: 0Ex ia IIC T6…T4 Ga X; [Fieldbus, FISCO, Profibus PA]:
0Ex ia IIC T4 Ga X
See Table 7-2 for Entity Parameters and Temperature Classifications.
Special Conditions for Safe Use (X):
1. The equipment must be installed in an enclosure which affords it a
degree of protection of at least IP20 in accordance with the
requirements of GOST 14254-96. Non-metallic enclosures must have
a surface resistance of less than 1 Ω; light alloy or zirconium
enclosures must be protected from impact and friction when
installed in a Zone 0 environment.
2. When fitted with the Transient Protector Assembly, the equipment is
not capable of withstanding the 500 V test as defined in GOST
31610.11-2014. This must be taken into account during installation.
3. See certificate TR CU 012/2011 for ambient temperature range.
7.10.3 KM Technical Regulation Customs Union TR CU 012/2011 (EAC)
Flameproof, Intrinsic Safety, and Dust-Ignitionproof
Standards:
GOST 31610.0-2014, GOST IEC 60079-1-2011, GOST
31610.11-2014, GOST R IEC 60079-31-2010
Markings:
Ex tb IIIC T130 °C Db X (–40 °C ≤ T
a
≤ +70 °C); IP66
See Table 7-1 for process temperatures.
See EM for Flameproof Markings and see IM for Intrinsic Safety Markings.
Special Conditions for Safe Use (X):
1. The non-metallic label may store an electrostatic charge and become
a source of ignition in Group III environments. Label must be cleaned
by the damp cloth with antistatic to avoid store an electrostatic
discharge.
