2.9.4 IECEx Certication

Model EJX Series pressure transmitters with

optional code /SU2 can be selected the type of

protection (IECEx Intrinsically Safe/type n or

ameproof) for use in hazardous locations.

Note 1. For the installation of this transmitter,

once a particular type of protection is

selected, any other type of protection

cannot be used. The installation must be in

accordance with the description about the

type of protection in this instruction manual.

Note 2. In order to avoid confusion, unnecessary

marking is crossed out on the label other

than the selected type of protection when

the transmitter is installed.

a. IECEx Intrinsically Safe Type / type n

Caution for IECEx Intrinsically safe and type n.

Note 1. Model EJX Series differential, gauge,

and absolute pressure transmitters with

optional code /SU2 are applicable for use

in hazardous locations

• No. IECEx CSA 05.0005

• Applicable Standard: IEC 60079-0:2000,

IEC 60079-11:1999, IEC 60079-15:2001

• Ex ia IIC T4, Ex nL IIC T4

• Ambient Temperature: –50 to 60°C

• Max. Process Temp.: 120°C

• Enclosure: IP66/IP67

Note 2. Entity Parameters

• Intrinsically safe ratings are as follows:

Maximum Input Voltage (Vmax/Ui) = 30 V

Maximum Input Current (Imax/Ii) = 200 mA

Maximum Input Power (Pmax/Pi) = 0.9 W

Maximum Internal Capacitance (Ci) = 10 nF

Maximum Internal Inductance (Li) = 0 µH

• Type "n" ratings are as follows:
