3.1 General
The EE300Ex is certified according to ATEX 2014/34/EU Directive, IECEX Scheme, National Electrical
Code ANSI-NFPA 70 (NEC©) and Canadian Electrical Code (CSA C22.1).
The use of the EE300EX in explosion hazard areas is only permitted under following atmospheric conditions:
-20 °C (-4°F)
0.8 bar (12 psi) ≤ p ≤
air normally 21 % (v/v)
The EE300Ex may be employed beyond above atmospheric conditions range only observing EN 1127-1
and only in line with the manufacturer's instructions.
The EE300Ex may only be supplied by intrinsically safe power supply devices or via protective barriers.
This applies also for the case when just the probe is located inside the explosion hazard area.
The rules for wiring intrinsically safe electrical circuits according to EN 60079-14, EN 60079-25, IEC
60079-14, IEC 60079-25 (proof of intrinsic safety in the system description) as well as all applicable
national regulations must be strictly observed. For the U.S., Canada refer to the Control
Drawing M1_1309080 (page 51) and ANSI/ISA RP12.6.01, NEC and CEC.
The intrinsically safe circuitry shall include an overvoltage protection device if the analysis according EN
1127-1 reveals a risk of lightning strike.
Requirements for the installation of overvoltage protection devices are set in European Normative EN
60079-25. For the U.S., Canada refer to ANSI/ISA RP12.6.01, NEC and CEC.
The manufacturing date of each EE300Ex is shown on the hazardous product label, at the bottom right
