Use 

This module is intended for use in conjunction with the EC 900 and/or CU 900. The module itself is 
used for electrical isolation of the interface signal and for power supply. The various intrinsically 
safe circuits are used to operate intrinsically safe field devices in areas subject to explosion 
hazards. 
The applicable laws or regulations concerning the use or intended use of the device have to be 
complied with. 

The data sheets of the ISS 900 include the electrical data of the EC type examination certificate 
and shall be deemed parts of the operating instructions. 
 
 

Installation and commissioning in areas subject to explosion hazards 

Installation and commissioning are to be carried out by specially trained and qualified staff only. 
The device has been designed in accordance with the IP 66 degree of protection as per EN 60529. 
External heating up due to solar radiation or other sources of heat must be avoided. 
The workmanship of the installation of the intrinsically safe circuits has to comply with the 
installation regulations in accordance with EN 60079-14.  
When other intrinsically safe field devices are interconnected with the intrinsically safe circuits of 
the associated EC 900 devices, the relevant maximum values of the field devices and associated 
devices have to be observed with regard to explosion protection. 
 
The EC certificate of conformity and/or EC type examination certificate have to be observed. It is of 
particular importance that the "Particular conditions" possibly contained therein are complied with.
