Emerson Rosemount 644R User Manual

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.

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.
