SP 1-Ex
3
Zones for installation of explosion-proof electric actuators and conditions for equipment installation are
defined in the following standards:
EN/IEC 60079-10: Electrical apparatus for explosive gas atmospheres
Part 10: Classification of hazardous areas
EN/IEC 60079-14: Electrical apparatus for explosive gas atmospheres
Part 14: Electrical installations in hazardous areas
Non-electric parts of electric actuators are designed, engineered, manufactured, tested and identified
in compliance with the requirements for safety of machinery according to the following standards:
EN 1127-1:
Explosive atmospheres – Explosion prevention and protection
Part 1: Basic concepts and methodology
EN 13463-1:
Non – electrical equipment potentially explosive atmospheres
Part 1 : Basic method and requirements
EN 13463-5:
Non – electrical equipment potentially explosive atmospheres
Part 5: Protection by constructional safety “c”
Equipment identification consists of the following characters:
Ex
- electric equipment complies with standard EN/IEC 60 079-0. and related standards for the corresponding
types of explosion protection.
d
- identification of the explosion protection type - "flameproof enclosure" according to EN/IEC 60 079-1.
e
- identification of the explosion
protection type
– „increased safety" according to EN/IEC 60 079-7.
tb
- identification of dust ignition protection by enclosure „t“ according to EN/IEC 60 079-31.
II or III
- identification of the class of non-explosive electric device according to the standard EN/IEC 60 079-0.
B
or
C
- identification of the
sub-class II
or III of non-explosive electric devices according to the standard EN/IEC
60 079-0.
T6 or T85°C
- identification of the
temperature class
of non-explosive electric device class II or III according to
the EN/IEC 60 079-0.
Gb
- (EPL Gb) - identification of the equipment designated for explosive gaseous atmospheres, with "high" level
of protection, which is not a source of initiation in standard operation or in case of expected failures.
Db
- (EPL Db) -
identification of the equipment designated for explosive dust atmospheres, having a “high”
level of protection, which is not a source o ignition in normal operation or during expected malfuctions.
1.4 Data specified on electric actuator
Nameplate for
Warning plate:
Nameplate contains the basic data concerning identification, performance and electricity: indication of producer,
type, serial number, max. load thrust and switching-off torque, operating speed, protection code, operating angle,
supply voltage and current.
Warning label:
-
with identification of the waiting time and requirements for strength of screws.
Non-explosive label:
identifying the manufacturer, certificate number, type identification, version identification,
serial number and version for ambient temperature -25°C to +55°C or -50°C to +40°C.
