Instructions specific to hazardous area installations
Model numbers covered: 2130***C*I***, 2130***N*I***
(“*” indicates options in construction, function and materials)
The following instructions apply to the equipment covered by certificate number
Sira 05ATEX2130X:
1. The Intrinsically Safe (I.S.). approved version of the 2130 may be used in a
hazardous area with flammable gases and vapors with apparatus groups IIC, IIB,
and IIA, and with temperature classes T1, T2, T3, T4, and T5.
The temperature class of the installation will be determined from the higher of the
process or ambient temperature.
2. The equipment may be used in a hazardous area with flammable dusts.
3. It is a special condition of the certification that the temperature of the electronics
housing is in the range of –50ºC to +80ºC. It must not be used outside this range. It
will be necessary to limit the external ambient temperature if the process
temperature is high. (See “Technical Data” below).
4. Suitably trained personnel shall carry out installation in accordance with the
applicable code of practice.
5. The user should not repair this equipment.
6. If the equipment is likely to come into contact with aggressive substances, it is the
responsibility of the user to take suitable precautions that prevent it from being
adversely affected, thus ensuring that the type of protection is not compromised.
Aggressive Substances: e.g. acidic liquids or gases that may attack metals or
solvents that may affect polymeric materials.
Suitable Precautions: e.g. regular checks as part of routine inspections or
establishing from the material’s data sheet that it is resistant to specific chemicals.
7. Technical Data:
a. Coding: II 1 G D, Ex ia IIC T5-T2, Ex iaD 20 (T85°C to 265°C) IP6X
b. Temperature:
2130***C*I*** and 2130***N*I***:
Minimum ambient air temperature (Ta) = –50°C
Minimum process temperature (Tp) = –70°C
c. Input parameters: Ui:15V, Ii:32mA, Pi:100mW, Ci:12nF, Li:60µH
d. Materials: Refer to part numbering identification chart.
