PROVISIONS FOR EXPLOSION PROOFNESS
5.1.
In terms of explosion protection, the explosion-proof call point IP535-07ea-RS meets the
requirements of TR CU 012/2011, GOST 31610.0-2014 (IEC 60079-0:2011), GOST IEC 60079-1-
2013, GOST IEC 60079-31-2013.
5.2.
The assembled call point with installed cable glands is an explosion-proof enclosure that
meets the requirements of GOST 31610.0-2014 (IEC 60079-0:2011) for electrical equipment of
groups II and III with high level of mechanical damage hazard. The call point casing has protection
IP66/IP67 as per GOST 14254-2015 (IEC 60529:2013).
5.3.
Explosion-resistance of the call point is achieved by means of application of explosion
resistant threaded and sealed connections as per GOST IEC 60079-1-2013.
Strength of each casing is checked during manufacturing via hydraulic tests by 1.5x explosion
pressure during the time necessary for inspection but not less than 10 seconds.
5.4.
Dust ignition protection is provided by means of application of ‘protection from dust
ignition by means of ‘t’ enclosures’. The parameters of connections of the casing elements comply
with the requirements of GOST IEC 60079-31-2013.
5.5.
Cable glands ensure strong and stable sealing of cables. Sealing elements and plugs meet
the requirements for explosion proofness as per GOST IEC 60079-1-2013.
5.6.
The explosion-proof manual fire call point must be used with cable glands and plugs of
the manufacturer or other certified cable glands and plugs that provide explosion protection type
‘explosion-proof enclosure’ and explosion protection level 1. The protection degree (IP) and the
operating temperature range of cable glands should correspond to the operating conditions of the
call point.
5.7.
Composition of the materials used for call point production provides its frictional intrinsic
safety and meets the requirements of GOST 31610.0-2014 (IEC 60079-0:2011).
5.8.
The maximum heating temperature of outer surface of the call point enclosure under
normal and emergency conditions does not exceed the values admissible for electrical systems of
the temperature classes Т6 as per GOST 31610.0-2014 (IEC 60079-0:2011).
5.9.
On the call point's body there is a nameplate indicating explosion proofness markings,
and on the cover, there is a warning ‘Unplug before opening’.
5.10.
Explosion-proof surfaces of the cover and the body are covered with anti-corrosion heat
resistant grease as per GOST 9433-80.
5.11.
The spring washer prevents the grounding clamp from loosening.
5.12.
Sealed lashing on the driving element prevents the cover of the explosion-proof casing
from self-unscrewing (to be installed by the customer).
6.
PROVISIONS FOR EXPLOSION PROOFNESS DURING INSTALLATION
6.1.
Conditions of operation and installation of the call point must meet the provisions set
forth in TR CU 012/2011, GOST IEC 60079-14-2013, Chapter 7.3 of the EIC (version 6),
Regulations for operation of consumer electrical installations, Chapter 3.4, safety regulations and
any other regulations as may be effective in the industry where the call point is applied.
6.2.
The call points must be used in accordance with the established explosion proofness
marking. Possible explosive areas of application, categories and groups of explosive gas, vapor and
air mixes are in accordance with the requirements of GOST IEC 60079-10-1-2013 and Chapter 7.3
